Special K : Valiam

"Fertilisers are routinely added to soil to enhance plant growth and increase crop yields. They include three main macronutrients: nitrogen (N), phosphorus (P) and potassium (K). If any of these macronutrients were to become unavailable or inaccessible to agriculture, a global food crisis of unprecedented scale would likely ensue. 

Potassium is integral to plant growth and animal health, but it is a non-renewable resource. Unlike nitrogen and phosphorus, whose supply and recycling details are well-documented, little is known about the potassium supply and consumption cycle. Although potash, the raw material used to produce potassium fertilisers, is abundant, it is located in the northern hemisphere, meaning its availability in the tropics involves a high transport cost.

By 2050, global demand for grain is expected to have increased by 60%, while global cropland area will have increased by only 10%. Estimates show that crop production needs to increase by 25%-70% above current levels to meet 2050 demand, but emissions and nutrient losses must drop dramatically in order to restore and maintain ecosystem functions. Can countries work together to close yield gaps in the Global North and South in order to feed humanity by 2050, when the global population is expected to exceed 9bn?"

"In 2016, just over half of the UK’s food supply originated outside the country, including 30% from the EU, 5% from Africa and 4% from South America. After Brexit, if the UK’s food imports originate less from the EU and more from countries in the Global South, the gaps between nutrient outputs and fertiliser inputs could widen (Figure 2). 

The UK is effectively mining nutrients from soils in the world’s poorest countries, which have no local fertiliser production. This makes food supplies even more vulnerable – especially when factoring in ongoing pressures such as climate change, which pose a significant risk to global food security. There are, however, opportunities for countries with no local fertiliser production to establish it, especially where there are known deposits that could be mined.

In many low and middle-income countries, minimal fertiliser is used for growing crops. Zambia uses the most fertiliser in sub-Saharan Africa, for example, at 46.2kg per hectare. This figure pales in comparison to the amount used in EU countries – 160.1kg per hectare. Latin America and the Caribbean use 127.9kg per hectare, and North America uses 126.6 kg per hectare. Countries with low fertiliser production should not necessarily be raising their fertiliser input to the same level as those with high inputs, because overuse is undesirable for increasing yields over the long term. To sustain the global food supply, fertiliser inputs will need to increase, but potassium inputs may need to double to compensate for what is removed by crops. In addition, intensification of agricultural lands is likely to be required in order to feed the rapidly growing populations in the developing world."

https://www.youtube.com/watch?v=Q5ETfsjRjzA

"What can be done about this global challenge? Local potassium fertiliser production in the Global South is urgently needed to enable agricultural systems in developing countries to feed local populations. National governments need to support geological exploration of potassium-bearing minerals such as potassium feldspar in Malawi, Ethiopia and Eritrea. It’s clear that the problem of potassium deficiency and other mineral resources for agriculture are not merely a global trade concern, and that much work remains to be done.

Geologists, agronomists and soil scientists must drive forward scientific initiatives to identify new potassium-bearing minerals and explore conventional mineral-based fertilisers in developing countries. Agronomic knowledge also needs to increase to allow us to understand the potassium status of soils, especially in Africa. This approach has been pioneered in Brazil, where the use of novel locally derived ‘remineralisers’ is federally regulated.

In addition, new markets need to be developed for alternative potassium fertilisers – a process that requires scientists, policymakers and economists to work together. The UK and EU countries stand to benefit from working with the Global South to secure food supplies both locally and globally. They can do this by discovering and investing in innovations such as mineral recycling, alternative mineral resources and alternative farming practices that improve soil quality and maximise yields. 

Scientific and policy leadership from the UK could help the developing world reach targets for the UN Sustainable Development Goals, to make potassium consumption and production responsible and sustainable. We must understand the impact that local consumption has on the global market – not just for potassium, but also for the other minerals and nutrients needed to maintain a healthy diet."

"... formed by the eruption of some rather puny volcanoes along the Carmel crest some time during the Cretaceous, when dinosaurs were prowling the land, geologists say...

The carmeltazite was found within sapphires, Shefa Yamim adds. Both regular sapphires and carmeltazite are based on crystalline aluminum oxide, this is true. Carmeltazite’s specific formula is ZrAl2Ti4O11.

In color, carmeltazite is black with a tendency to reddish streaks and a metallic luster, though if one squints through various instruments one can discern dark browns and greens. And white spots (“It depends on the angle of light,” Taub observes). Internal reflections are absent, the geologists add in their characterization of it."

"More than 1,500 metres beneath the rolling beauty of the North Yorkshire moors, a rich seam of mineral wealth that stretches across hundreds of square kilometres could bring billions to the regional and national economies.

It’s not oil or gas that lurks there but a naturally occurring mineral called polyhalite, a substance formed more than 250 million years ago, which contains sulphur, calcium, potassium and magnesium, four of the six elements essential for plant growth.

It has the potential to revolutionise the world of agriculture. It’s an organic fertiliser whose extraction and refining creates practically no waste product. If things go to plan, it could be taken out of the ground and sent to market within the space of a day by 2021.

The mineral will be mined, taken over tens of kilometres on a subterranean conveyor belt, then ground down and processed at a site next to a deepwater port. From there it will be shipped across the globe to confirmed customers in Asia, the Americas and beyond.

With the world's population set to hit nine billion by 2050, the 21st century is going to be defined by the struggle to feed more and more people from shrinking agricultural land resources. Advancements in fertiliser technology are going to be at the forefront of that fight.

Sirius Minerals, a mining company formed in 2003, believes that with polyhalite – to be marketed as POLY4 – it has found a product that will potentially bring in more than £2.5bn of exports a year when the project is running at full capacity by the late 2020s and create thousands of jobs.

However, before Sirius can even take a single tonne from the ground, they will have had to embark on one of the most extraordinary extraction operations seen in the industry, one that will see the deepest mine in Europe sank and the longest tunnel in the UK built.

Three kilometres inland from the picturesque seaside town of Whitby, the main site of the project is at Woodsmith mine, below the North York Moors National Park, a protected expanse of more than 1,430 square kilometres of heather moors, pasture and woods.

The mine will consist of two shafts sunk to 1,520m, the level of the 70m layer of polyhalite. Remotely operated machines will excavate the mineral, and it will then be taken up to a depth of 360m, where the 37km conveyor belt will take it to the handling facility at Teeside harbour.

Whereas the mining of most ores creates more waste than finished product, the purity of the seam at Woodsmith means all that will happen to the mined mineral is that it will be ground down and turned into POLY4 granules, before being loaded on to ships.

To assuage local fears that the project would compromise the landscape, Sirius has committed to industrial standards which will see more records claimed in this, the first new mine to be sunk in the country for 40 years.

The headframes – structures which contain the winching equipment that operates the lifts in the shafts – will be entirely underground, a unique feat. Construction of the shafts will be a novelty, too: the initial 120m will be bored down, rather than blasted with explosives, a British first. And the machine drilling down to 1,500m has only been used twice before around the world.

The entire footprint of the mine when the site is fully operational will consist of a scattering of agricultural-style buildings – the entire site will also be covered by 7,000 hectares of woodland, allowing for the carbon emissions of the construction period to be offset.

As Maurice Rankin, general manager of corporate communications for Sirius, says: “Sustainability [has been] at the core of everything we do – sustainable mine design, with as low an environmental impact as possible and stringent mitigation measures where necessary.

“This has resulted in unique innovations such as the sunken headframes and the underground transportation system, which had never been done before anywhere else in the world, to create an essentially invisible mine that will disappear into the landscape, at the same time as providing economic opportunity for generations to come.”

The company is currently in the middle of a second round of financing. The initial stage raised $1.2bn (Dh4.4bn) in 2016, which has funded the advanced state that both the Woodsmith and Teeside sites are in.

By the end of Q1 in 2019, Sirius aims to have secured an additional $3.4-3.6bn – $1.5bn in commercial loans matched by the same figure in a loan guaranteed by the British government, with the excess likely to come from the capital markets."

In for a penny ...

"Sirius Minerals has unveiled the first of its 1,800 tonne tunnel boring machines (TBM) that will construct the company’s underground mineral transportation tunnel between Whitby and Teesside.

The 225-metre-long machine is undergoing final checks in Germany before being shipped to Teesside in the coming weeks, where it will be reassembled and start tunnelling in the second quarter of the year. Primary schools across Redcar and Cleveland have been given the opportunity to enter a competition to name the first machine.

The single-shield TBM will be operated by leading construction firm Strabag, who also worked on the 35 mile Gotthard Base Tunnel under the Alps. Initial excavations have already begun to prepare for the machine’s arrival.

The machine will bore the first of three planned tunnel drives which will make up the 23 mile tunnel from a new underground mine, near Whitby, to a processing facility on Wilton International in Redcar. Two other machines are planned to be launched in 2020 from Whitby and Lockwood Beck, near Guisborough, to complete the final 15 miles of the six-metre diameter tunnel. Workers will operate the TBM 24 hours a day, 7 days a week, lining the tunnel with concrete segments as it goes.

When complete, the tunnel will transport up to 20 million tonnes a year of polyhalite ore on a conveyor belt from the mine, to a purpose-built processing and shipping facility in the shadows of the old Redcar Steelworks, for distribution around the world. A tunnel was chosen as the transport solution to avoid impacting the local landscape and will have no impact on the ground above, sitting at an average of 250-metres below ground level.

Chris Fraser, Managing Director and CEO of Sirius said: “The assembly of our first tunnel boring machine represents an exciting milestone for the company and the region. With around 1,000 people currently employed across all of our sites, the team working to make this project a success continues to grow as we deliver this world class project. We expect to create hundreds more skilled construction roles in the coming months to help build our mineshafts, tunnel and mineral handling facility.”

Sirius expect to reach the polyhalite seam in 2021 and to be producing 10 million tonnes of fertiliser per annum by 2024, bringing about around 1,000 new long-term operational jobs."

"The funding package for the Woodsmith mine will now comprise three rather than two tranches, which will be drawn sequentially and linked to construction milestones.

The first portion is expected to be a $500m to $700m high yield bond, according to analysts, followed by $1.5bn of bank debt and a further $800m to $900m of loans guaranteed by the UK government’s Infrastructure Project Authority. Sirius said the new structure had been designed to reduce the risk to the UK taxpayer because the IPA debt would only be drawn once sales had started and the main construction risks had passed. However, analysts said the plan would result in higher financing costs, at least in the short term. Sirius has previously been looking to raise $1.5bn from government-basked loans.

“Each tranche of this new structure will be fully committed from the start and, whilst it may raise the cost of the debt for the high-yield bond, this could be possibly offset with lower rates for the IPA at the end of the construction period,” said Liberum analyst Ben Davis. Shares in the London-listed fertiliser mining group dipped 4 per cent to 21.5p, giving the company an equity market value of £1bn.

Woodsmith is the largest mine to be built in the UK for a generation. The highly ambitious project involves sinking two 1.5km shafts below a national park on the North York Moors to access a massive deposit of polyhalite. The ore will be extracted via the two mine shafts and transported to Teesside on a conveyor belt system via a 37km underground tunnel. It will then be granulated at a materials handling facility, with the majority being exported to overseas markets.

Its shares fell sharply in September after the miner said it needed to raise a further $400m to $600m of equity to cover extra costs associated with the tunnel. Sirius, a favourite of UK retail investors, has yet to secure the extra funding but supporters say Woodsmith is exactly the sort of project needed to make a success of the government’s Northern Powerhouse policy and was discussed during Prime Minister’s Questions last week.

“The Treasury department that is working on the investment guarantee does not have a Brexit mandate and is not being distracted by the unstable political landscape,” noted Mr Davis. “The collapse of two proposed nuclear plants, whose financing requirements are longer dated and more complex, only drives government harder to deliver investment in the North.”

Although polyhalite is a relatively unknown product, Sirius has secured commitments to purchase up to 8.2 tonnes a year of output from the mine, scheduled to open in 2021. The company did not announce any further offtake deals on Tuesday but said it was in advanced negotiations with a European partner. “Progress at Woodsmith appears to be largely in line,” said analysts at Numis. “However, the challenging elements of this very large scale build remain ahead and, over the short term, securing funding remains the key catalyst.”

"We understand the sale of the Sirius building is imminent and there are rumours that the Opal Towers developer Ecove is the government's preferred buyer," they wrote in an open letter to Premier Gladys Berejiklian.

"Such a sale would be a grave mistake and would provoke distrust in government processes and objectives."

So far so good..

"Analysts at Cazenove said that while the new structure "mitigates the projects' reliance on the IPA/UK government guarantee, the addition of the uncovered bond adds another degree of complexity which could put at risk the prior timing for financial close by Q1'19".

"It also puts upward pressure on the interest cost, where prior guidance (unchanged in today's release) is for an "all-in" cost of 6-7%. We reaffirm our view that the near-term equity thesis will be dictated by SXX's ability to secure the next tranche of financing, and as such look for additional procurement contracts and off-take agreements as focal points going forward."

Broker Liberum said: "Given its strategic importance to investment and jobs for the 'Northern Powerhouse' policy, it remains a priority focus for the government to see the work done. Following Theresa May's defeat on her Brexit deal, it was the Sirius Minerals project that was one of the first questions to be asked at PMQs.

"The Treasury department that is working on the investment guarantee does not have a Brexit mandate and is not being distracted by the unstable political landscape.

"If we are having problems raising finance for a gold plated tunnel it is time to do some value engineering.

On the west coast at Whitehaven, West Cumbrian Mining are proposing to access an offshore seam of high quality coking coal using the pair of adits (drifts) originally constructed in 1952 for Marchon's (Solway Chemical's/Albright & Wilson's) Sandwith Anhydrite Mine. Since discovering that the costs of dewatering the old anhydrite workings would be prohibitive their proposals have recently been modified but investigations have been carried out on these adits which are intact after 66 years. These tunnels do not appear to be fully lined, certainly not doubly lined.

https://www.westcumbriamining.com/company-news/west-cumbria-mining-successfully-completes-initial-underground-investigations-sandwith-anhydrite-mine-drift-inspection-works/

These do not appear to be fully lined tunnels but are intact after 66 years

Why do we persist with our over-engineered fully lined "channel tunnel" when we are expecting it to be driven in a competent low permeabilty Redcar Mudstone?

There may also be advantages from an alternative "D" tunnel design in that both conveyor and maintenance railway may be floor mounted with only cables and pipework hung.

From document 40-STR-WI-230-EN-00004.C/HRA
Hydrogeological Risk Assessment – Phase 5 – MTS – Drive 1 – Wilton to Lockwood Beck
(page 38 of 49)

“the competent Redcar Mudstone Formation bedrock is of low permeability and is likely to be of very low storage coefficient. Therefore, the reduction of groundwater pressure around the tunnel is likely to occur rapidly and recharge through the mudstone will be very slow “

So, how necessary is a (thicker) lined tunnel?

"competent" - doesn't deform easily/will withstand loading (as with the main mine design in polyhalite).
"low permeabilty" - groundwater seeps slowly.
"low storage coefficient" - initial flows likely to be low.
"recharge slow" - unlikely to deplete aquifer.

The comparable Kielder Water scheme tunnels, (35 miles upstream from Wilton) were post lined at 200mm (in order to carry the water rather than physical integrity?) and have been in service for forty years. Many of the Durham deep coastal coal mine main roadways had no lining and in service for over a hundred years??

I am not a geologist or a tunneller merely a small investor wanting the best outcome for this project.

"on 20th February there is a Royal Town Planning Institute meeting in York (£35 + Vat) which will cover both Sirius and Fracking [There was what appears to have been a very interesting Enquiry into the Minerals Plan in North Yorkshire held early in 2018 in Northallerton in front of Mrs Ord (There were submissions from Sirius): The conundrum; do you prevent the exploitation of the natural gas (shale gas) by developing a fertilizer mine, or preclude the exploitation of a fertiliser mine by fracking for shale gas? From either does the seismic/deflection/subsidence impact the MOD's Fylindales radar...]

From the flyovers - What is the drilling rig doing back over the Production Shaft. It had an extended stay there to prove-up some of the geology and yet it is back?? But the evidence of concrete placement and spoil out bodes well for progress by "Bessie" the VSM on the MTS shaft.

Hope there's something in the above to provide interest and amusement while we await the St2 RNS. I'm very impressed that Sirius put so much information out directly and that the phased planning documents are all uploaded by the authorities for open public access. Back in the 1970's there was little such easily available public information on the Kielder tunnels but nor was there any site security in Rogerley quarry, Frosterley, so as a teenager with a dim torch I was able to wander down the trial adit at the weekend and see what the tunnellers had been up to (good job there was no gas 'cos the ventilation fan wasn't running either!).

Now on to the local history of tunnelling in the 1970s. 35 miles as the crow flies upstream from Wilton is the Eggleston southern portal of the Kielder Water Scheme which involved 32Km of 3.5m diameter hard rock tunnels between the Tyne, (Derwent), Wear & Tees. It was predicated on supplying the burgeoning requirement for water by the chemical industry on Teesside. All paid for by the public purse. By the time it was completed improved efficiency of water usage and declining industry meant it was a white elephant. This was a comparable tunnelling exercise. For Woodsmith/Lockwood/Wilton read Eggleston/Frosterley/(Riding Mill). By comparison Sirius is to be an entirely privately funded undertaking...

Kielder water scheme: https://trl.co.uk/sites/default/files/SR676.pdf

Compare & Contrast with Sirius' proposed 70m pillar (must be very competent material this polyhalite) and the stall taken in 3 slices.

Historically sinking mineshafts has been a risky business both physically and financially. Read under Description in this museum reference for the sinking of Murton Colliery in 1838.... 3 tanneries working full time to keep up with the wear on the pumps from the running sand...

http://www.dmm.org.uk/colliery/m006.htm

So, 180 years and 40 years on is our (German!) technology going to deliver the shafts and tunnel so much quicker???

When we moved from the proposed polyhalite slurry pipeline to the underground conveyor in a tunnel it was stated that this was a "mine roadway" not to be confused with a lined Crossrail or Channel Tunnel. However, it has morphed into just that. Will someone confirm why this has to be? Is it the hydrogeology in the Redcar Mudstone? I do not recall the Durham coastal pits having extensive concrete segment factories? They went miles out under the north sea, mined longwall and the strata was allowed to collapse behind (see above). I've a suspicion that whilst there are undoubtedly some groundbreaking innovations there is a degree of belt & braces sneaking into this project with engineers/geologists/contractor organisations being driven more by protecting themselves from later criticism than exercising entrepreneurial flair. Bankers and risk, eh? What's that about the camel being a horse designed by committee?

Thank you to the posters who first spotted the Local Liaison Meeting at Sneaton Village Hall YO22 5HS 1 -2.30pm on Thursday 7th February. This presents a slight quandary as the previously booked Midlands Institute of Mine Engineering meeting starts at 4pm, 70 miles away at MRS Knottingley WF11 0BU "Technology applied to the high performance winding systems at Sirius Minerals" by Peter Hetherington and Sid Brady, both of Sirius. I'm intrigued how the LNG gas engines will be run. Even if there are not Fault Current issues it'll be Island Mode I guess to avoid depressing the voltage in Whitby when the winder operates... or are the power electrics so good these days that governors can react to maintain stable voltage when the heavy loads come on?"

Awesome ;-

"Sirius Minerals aims to become one of the world’s leading producers of multi-nutrient fertilizers. Their central purpose is to make a significant and sustainable contribution to global food security, one of the most important challenges facing the world today.

The Woodsmith Mine has been called the most mitigated mining project in the world. The project incorporates sustainable design and operations, minimal construction impact and energy efficient processes. Furthermore, Sirius Minerals have worked hard to safeguard and enhance the environment and support sustainable agricultural practices.

However, it is the firm’s commitment and desire to go above and beyond what was required by regulators and planning that impressed this year’s judging panel.
During 2018, mains power installation on site has almost eliminated the need for diesel generators, and in the coming months the installation of an LNG plant will offer cleaner, more sustainable power in the future.

Also, despite a simple granulation process that is free of chemicals and waste, designs have been optimised further – reducing power consumption by around 50%, lowering the thermal energy burden and removing the need for additional raw materials in the process.

Many, many environmental, landscape and ecology projects have been supported too. Locally sourced rare wildflower mix has been seeded; a wetland habitat established, and 7,000 hectares of carbon offsetting woodland will be created – that’s 10 million trees to you and me! Since just 2017, £700,000 of funding has been provided for local environmental projects."

If only we had an Eden project ... of the satellite variety.

MIME Winding Systems

"Midland Institute of Mine Engineering meeting at MRS Knottingley 7 February 2019:
Application of technology in the high performance winding systems at Sirius Minerals by Sid Brady & Peter Hetherington, both of Sirius. - rough notes E&OE

The design is near cutting edge consistent with proven technology except in two development areas (optical miscoil detection, Levelock skip/cage holding system, winder control & protection?).

For production operation the 2 x 66kV cables in the tunnel will bring power from Wilton

Lockwood Beck intermediate shaft will now start sinking in April.

Both main shafts are 6.75m diameter and the installed hoisting capacity will be capable of 13.4MTPA.

The Blair type winders from OLKO. Winder shafts cast in Czech Republic (at Vitkovice?)

Production shaft has a second winder capable of back-up hoisting of 12 men.

The service shaft is the downcast shaft and capable of delivering men & material from -43m to -1540m

Double Drum Blair type winders. Drums all 6m diameter.

Rope 56mm diameter type Tiger 6 x 28TS (triangular section strand)

Safety Concept is a twin PLC system with comprehensive self checking and monitoring with features to reduce scope for common mode failure (Peter described the system in arcane detail).
Comprehensive speed/distance monitoring & control with multiple checks for out of normal especially approaching bank.

Production winding cycle graphs were presented. A maximum short duration load rising to 17.3MW is drawn as the skip accelerates (MCR rating of the motor is 9.3MW but forced air cooling and insulation temperature monitoring allows this intermittent overload operation).

The skip sits on the bottom during loading (otherwise 1.5m stretch in rope). The winder takes up the tension slowly during initiation before driving to maximum acceleration.

OLKO are a young company (8 years) but many of the personnel are ex-Siemag.

Normally all winding uses electrical ******ation (regenerative?). Disc brakes are only for emergency and parking. They are applied by spring and held off by hydraulic systems that provide a comprehensively controlled sequence of application to generate constant ******ation. Sid described in detail the multi-redundancy in the electro-hydraulic systems that monitor the multi-calipers and apply the necessary hydraulic pressures to ensure each achieves the required braking effect irrespective of individual pad friction.These systems are certified and separately tested and approved by the German Mining Authority and independent certifying body (DMT?)

With the comprehensive rope management and avoidance of instantaneous shock loading rope ultimate safety factor may be reduced from the UK historical 5.5:1 to in this case 5.08:1. Sirius have examined best practice in South Africa where the deepest mines are now down to a 3.4:1 factor of safety. 140k cycles is typical rope life which would give 18 months at Sirius. They hope for more.

The floating drum (on the production shaft at least) is to have roller bearings (not plain) so that it may be declutched to bring skips to the surface not just the -360m level.

Experience of mechanical miscoil detectors in South Africa is that they provide inadequate indication that a rope has jumped. Sirius are therefore adopting an optical system that will “learn” the normal coil shape and initiate a safety trip in case of any abnormality.

There will be a WiFi Kinetic Mesh for comms & data.

To avoid movement of the skip during loading & unloading the Levelock system will be used. This will also be adopted for the service cage (?). The skips are rope guided which is unusual for this depth

For air management at the -360m level there is a bulkhead at bunker bottom and a plug of mineral is always left in the bunker (or shut-off slide for maintenance).

The two bunker outlet conveyors discharge onto either of two cross conveyors which feed the main tunnel belt. Tramp detection is fitted so that either of these cross belts will automatically stop while the problem is investigated before the stray material reaches the tunnel belt. The bunkers automatically switch to continue to feed the other cross belt and mineral transport is not interrupted.

During shaft sinking the 11kV 10MVA supply from the Northern Power Grid Spital Bridge substation in Whitby is supplemented by both the LNG power house with 4 x 1.5MW generators (with space for two more) and a “6 MW” battery. These are expected to operate connected (fault rating of Northern Power Grid switchgear at Spital Bridge must therefore be adequate?). Winder power consumption during shaft sinking is estimated at 3MW and the battery is there primarily to meet instantaneous winder demand.

The 11kV supply from NPG will be retained for emergency (rescue) supply in the event of loss of the 66kV from Wilton through the tunnel.

End of meeting notes.

Verulam cogitates how heavy engineering in the UK has been allowed to wither. All the heavy kit appears to be sourced from abroad. As my post of 21 January: When the similar 35km x 3.5m diameter hard rock tunnels for the Kielder Water Scheme were constructed 35 miles upstream from Wilton they used UK built TBMs. Not as sophisticated as the Herrenknechts but that was 40 years ago. And only a 200mm liner to contain the water. I still haven't found why we have moved from a “mine roadway” to Strabag's double thickness fully lined tunnel when we are expecting to be in competent low permeability Redcar Mudstone

Kielder water scheme: https://trl.co.uk/sites/default/files/SR676.pdf

Would love to have chapter & verse on the hydrogeology that demands Strabag's solution. Are we in danger of over engineering to the extent that shareholders' funds are exhausted..."

"The Sirius Minerals Foundation has announced another £215,000 for local community projects across the area. 

In its latest grant giving programme, seven charities from the Yorkshire and Teesside coast will benefit from funding to spend on education programmes designed to enhance local people’s skills, which is one of the core aims of the foundation.

The organisation is an independent charity funded by Sirius Minerals Plc - who has its headquarters in Scarborough - to create a lasting legacy from the development of the company’s multi-billion-pound polyhalite fertiliser mine being constructed near Whitby and Teesside. 

This is the second funding round for the charity, having distributed £300,000 to 80 projects throughout Teesside, east Cleveland, Whitby and Scarborough in December 2017.

The criteria for this funding round centred on skills development, with the Foundation deciding to award between £10,000 and £50,000 each to the following groups:

  • YMCA Scarborough ‘Youth Matters’ - The’ Youth Matters’ project is to build voice, capacity and engagement and also increase social mobility for up to 40 participants, aged 13-18 (and up to 25 for those with additional needs) across the North Yorkshire Coast Opportunity Area.
  • East Cleveland Youth Housing Trust – ‘Constructing Communities’, creating two 24-month construction-based apprenticeships for local young people. The Trust will be able to deliver more community-based projects and help increase the living options for those in housing need.
  • Coatham House in Redcar – ‘Reloved’ project offering 3 new apprenticeships for local young people in the catering and service trade working with the local college. The resources will help build capacity in terms of offering more work placements and volunteer opportunities offering accredited training to help clients progress into the world of work.
  • SASH in Whitby and Scarborough – ‘Improving Skills’ project to improve literacy and numeracy for young people at the risk of becoming homeless. In includes targeted and personalised support for each young person to obtain qualifications in both Maths and English.
  • Age UK – ‘Health, Wellbeing and Employment’ programme to help over 50s return to work in the area offering in-house group and 1-2-1 help with the main issues facing the older population.  The charity will be using a holistic approach to help these individuals move closer to the job market and look at all aspects of their lives.
  • Northern Regeneration CIC – Funding of the Construction Skills Village, to increase opportunities for people to gain construction skills by delivering a series of bespoke plant training and employment packages to support local individuals develop demand led skills in construction. This training will help support individuals to apply for demand led jobs in both the broader construction industry and Sirius Minerals mine when trained.
  • Community Furniture Store Ryedale in Scarborough – delivering a structured training programme to extend the work with people who are unemployed and face barriers to entering or re-entering work due to lack of skills and confidence.

David Archer, chairman of the Foundation commented:

"The Foundation has been deliberately designed to put money back into the community and ensure that local people benefit directly from the success of the mine. 

There can be no better long-term benefit to an area than having more people with better skills, so it seemed only right that we focus on this area this time around. 

The successful applicants impressed us with the thorough planning and clear focus of their programmes, which will create tangible outcomes that will make a real difference to people’s lives on the Teesside and North Yorkshire coast.”

The foundation has been given £2m in funding while the mine is under construction. 

Once the mine is complete, the foundation will be funded by an annual 0.5% cut of sales, which could be as much as £13 million per annum. 

Gareth Edmunds, External Affairs Director at Sirius Minerals and Trustees of The Foundation, commented:

“Sirius intends to continue to be an integral part of the community in North Yorkshire and Teesside for many decades, and the Foundation is an important way to help us give back to local people and provide a lasting legacy for the community. 

It’s great to see another round of hard working organisations benefit from this latest round of founding”.

"As an apprentice engineer with us, you will study for a nationally-recognised qualification while gaining paid, hands-on experience on one of the most exciting mining projects in the world. It's an exciting, multi-skilled apprenticeship programme which will focus on developing a sound knowledge of electrical, mechanical and instrumentation principles and putting those into practice....

Applications are open until April 2019, when successful candidates will be invited for a skills" assessment and interview."

TBM Arrival

"The first of three tunnel boring machines which will create a 23-mile (37km) long tunnel for the extraction of mined fertiliser has arrived.

Sirius Minerals plan to transport up to 10 million tonnes of polyhalite a year from Whitby to Redcar.

The main parts of the 1,800-tonne boring machine arrived on Teesside after seven days en route from Germany.

Children in Redcar and Cleveland will choose the machine's name when it starts boring later in the year.

Polyhalite is a naturally occurring fertiliser which will be taken by an underground conveyor belt from the mine near Whitby to a processing plant near the former Redcar steelworks..."
