Kalium Lakes says it has awarded a contract to design, supply, install and commission a 7.5 MW gas fired power station for its Beyondie sulphate of potash project (BSOPP), in Western Australia, to Clarke Energy.

The scope of the contract includes three Jenbacher 616, 2.5 MW gas reciprocating engines, a Kohler KV440C2 black start generator, high and low voltage switch rooms, auxiliary equipment and the power station controls system, according to Kalium Lakes.

Gas for power generation will be supplied from Kalium Lakes’ owned and operated gas lateral that will also be built as part of the project for the stage one 90,000 t/y SOP production capacity.

The project aims to commence production at 90,000 t/y of SOP, before ramping up to 180,000 t/y of SOP for domestic and international sale. An initial mine life of between 30-50 years is anticipated for a project designed to be a low cost, long life and high margin producer, Kalium Lakes says.

According to the potash developer, the scope under this contract has already commenced with early works to de-risk the project schedule and enable early contractor involvement for optimal integration with the power generation requirements of the project.

Clarke Energy has also provided several smaller, diesel generators for the project from its signature Kohler brand, which will provide power to the village and the remote brine transfer pump stations, Kalium Lakes said.

Kalium Lakes’ Chief Development Officer, Rudolph van Niekerk, said: “Not only has Clarke Energy worked with us to find a technically viable solution for our project, it has gone the extra mile to also achieve the WHS Accreditation which is a requirement for this contract under Kalium Lakes’ funding from the Northern Australia Infrastructure Facility.”

Earlier this month, Kalium Lakes’ board made the final investment decision on the project, allowing development to move forward.

Jaylon Environmental Systems is to supply and install the evaporation pond liner at Kalium Lakes’ Beyondie sulphate of potash project (BSOPP), in Western Australia, as part of a contract agreed between the two parties.

The contract includes the supply, management of delivery and installation of 1 mm HDPE liner covering a total evaporation area of approximately 400 ha for the Stage 1 BSOPP 90,000 t/y sulphate of potash (SOP) facility.

The BSOPP project aims to commence production at 82,000 t/y of SOP in 2020, before ramping up to 164,000 t/y of SOP for domestic and international sale. An initial mine life of between 30-50 years is anticipated for a project designed to be a low cost, long life and high margin producer, Kalium Lakes said.

Earlier this month, Kalium Lakes secured gas supply and transport for Beyondie SOP project following deals with APA Group and Shell Energy Australia.

In 2017, Jaylon successfully completed the supply and installation of the liner for the BSOPP’s 10 ha pilot scale ponds, according to Kalium Lakes. “Jaylon has now submitted the most competitive and compliant offer for the full project works, resulting in this A$15 million ($10.3 million) major contract award,” the company said.

The scope under this contract has already commenced, with an initial order of A$1 million worth of liner placed in May 2019 as part of early works and first deliveries to site already completed. The balance of the contract scope will commence following a final investment decision (FID) by Kalium Lakes, due shortly.

Kalium Lakes Chief Development Officer, Rudolph van Niekerk, said: “The use of Jaylon during the pilot scale trials continued to validate Kalium Lakes’ de-risking strategy, where we work collaboratively to develop bespoke, low cost and fit for purpose solutions for the BSOPP.

“The use of an evaporation pond liner has been a much-debated topic. For Kalium Lakes, the cost of the supply and installation of the liner represents less than 7% of the project’s total capital cost but results in an increased SOP process recovery of more than 15%.

“Our lined pond design provides a pond system constructed on trafficable, off lake surfaces, allowing for harvesting by heavy machinery months, if not years, ahead of the alternatives.

“With lined ponds there is virtually no leakage of the high value concentrated brines, delivering excellent recovery rates, a smaller pond area, less brine pumping, low operating costs and an extended mine life. It simply is a ‘no brainer’,” he said.

Stuart Olson to help construct Western Resources’ Milestone Phase I potash project

Western Resources’ wholly owned subsidiary, Western Potash Corp, has entered into a lump-sum agreement with Stuart Olson Prairie Construction to become the General Contractor for the Milestone Phase I potash project, in Saskatchewan, Canada.

Stuart Olson is one of the largest and most respected construction services companies in Canada, according to Western Resources. “Their unique approach to doing business, as well as extensive construction and industrial services proved a perfect partner for the project,” the company said, adding that the company will be drawing a large proportion of its trades from the local area.

Milestone Phase I will be the newest and most innovative, environmentally friendly and capital efficient new potash mine in Canada, according to the company. The plan is to produce 146,000 t/y of potash over a 12-year period.

Using advanced drilling techniques, the project intends to initially target the high-grade potash bed, with selective dissolution preferentially leaching the potash to the surface. “This means that any salt is left underground and there is no tailings pile at the surface, thereby reducing the water consumption by half,” Western Resources explained. The potash is then crystalised naturally in a pond due to the temperature change, resulting in much lower energy consumption and a capital cost proportionally less than other solution mines, according to the company.

The project has already completed the early work to prepare the site including an access road, site clearing and piling foundations, water well, water pipeline and power infrastructure. The civil work of the crystallisation pond has also been completed, with the site now ready for the start of full construction with Stuart Olson.

Stuart Olson’s General Contractor scope will include the construction of all above ground facilities, including concrete, steel and pipework, installation of equipment, electrical and control system work, building work and site finishing. Its team will mobilise to the project site in June, with an anticipated maximum workforce of around 100 people on site.

“With their heritage in Western Canada and diverse experience, they have the skills, experience and resources to complete the project safely on budget and schedule,” Western Potash said.

Bill Xue, Chairman of Western Potash, said: “The management and Board of Directors are very excited to partner with Stuart Olson to build this innovative and efficient new mine in Saskatchewan. The project will benefit from the strength and experience of Stuart Olson, and we look forward to the next milestone, the start of production in mid-2020.”

BCI Minerals says it has appointed GR Engineering Services as the lead engineer for the Mardie salt and potash project definitive feasibility study (DFS) on the northwest coast of Western Australia.

As lead DFS engineer, GR Engineering will be responsible for coordination and integration of the process and engineering design packages for the ponds and crystallisers, salt plant, sulphate of potash (SOP) plant and port facilities. It will also prepare and verify the DFS level capital and operating cost estimates and will undertake the design and supervision of pre-final investment decision site works and supporting infrastructure during 2019.

BCI said: “GR Engineering is a reputable Perth-based engineering group with significant experience in study management, engineering design and construction of resource projects in Western Australia and globally, both as engineering, procurement, construction and management and EPC contractor.

“Members of the GR Engineering team nominated for this engagement have appropriate experience in salt operation and sulphate of potash study management.”

Following completion of a prefeasibility study during the June 2018 quarter, BCI commenced the Mardie DFS. As well as improving design accuracy and further de-risking the project, BCI is aiming for the DFS to improve on the PFS development plan and business case in a number of key areas, including:

  • Increasing the production capacity to 4 Mt/y salt and 100,000 t/y SOP;
  • Establishing the tenure, approvals and designs for a fit-for-purpose export facility at the Mardie site, which will eliminate haulage costs to the Cape Preston East Port site, and;
  • Establishing test ponds and completing construction of project support infrastructure to bring forward the target date for first salt and SOP production.

The site works GR Engineering will initially carry out include a 135-ha trial pond, seawater intake pumps, circa-20 km upgrade of access roads, initial accommodation camp and power generation.

BCI’s Managing Director, Alwyn Vorster, said: “We are focused on delivering a high quality DFS that will place BCI in a strong position to reach a final investment decision by the first (March) quarter of 2020. GR Engineering’s technical ability and project management strengths will make them a valuable partner to BCI as Mardie is progressed towards full project construction.”

BCI’s areas of focus in the period to June 30, 2019, include:

  • Appointments of process design engineers (ponds, two plants and port);
  • Geotechnical drilling programme of pond, plant and port areas completed;
  • Construction of small-scale trial evaporators completed;
  • Port tenure negotiations with the Pilbara Port Authority(PPA);
  • Environmental Review Document submitted to the Environmental Protection Authority(EPA);
  • Construction of the 135-ha trial pond and supporting facilities (camp, roads, power, pumps) commenced;
  • Funding discussions with Northern Australia Infrastructure Facility and other entities progressed;
  • Product offtake potential developed, and;
  • Significant potential investor/financier briefings.

BCI said all activities until the final investment decision in Q1 2020 – estimated at A$25 million ($17.8 million) – will be funded from BCI’s existing A$36 million cash and the ongoing quarterly royalties from Iron Valley, the company said.

Australian Potash close to sulphate of potash milestone at Lake Wells

Energy minerals, Industrial minerals, Mineral processing, Mineral project development, , , , , ,

ASX-listed Australian Potash says it is poised to become the country’s first producer of sulphate of potash (SOP) from field evaporated salts after its pilot plant facility received 3 t of the final potassium-rich harvest salts from the Lake Wells pilot evaporation programme.

This announcement, made at the end of December, should lead to the company producing SOP from the project, in Western Australia, this month, according to Managing Director and CEO, Matt Shackleton.

“One area of focus for Australian Potash’s project team over the past 12 months has been to develop and refine the site evaporation model,” he said. “Understanding the chemistry of the salts that are produced through the natural evaporation cycle is crucial to planning both the commercial scale development and SOP processing strategies.”

“In January 2019, we plan to produce Australia’s first field evaporated SOP, which will be of enormous value to Australian Potash and our MOU (memorandum of understanding) offtake partners, as we will be able to detail the chemical composition of the SOP we can produce.”

Shackleton said 2019 was set to see the commissioning of a greenhouse SOP-MOP (muriate of potash) trial managed by the University of Western Australia’s School of Agriculture and Environment. “The trial will also be supported by field trials across at least five sites, examining the effect of SOP versus MOP,” he added.

Australian Potash expects to publish a definitive feasibility study on the Lake Wells potash project, around 500 km northeast of Kalgoorlie, in the second half of 2019. This will build on the results of a scoping study, which showed a stage one production rate of 150,000 t/y of “premium-priced” SOP (years one to five), a stage two production rate of 300,000 t/y of “premium-priced” SOP (years six to 20) and a pre-production capital expenditure of $135 million for stage one and $125 million for stage two.

STRABAG wins MTS contract for Sirius UK polyhalite project

Sirius Minerals has varied its existing mineral transport system (MTS) tunnelling contract with STRABAG AG to include the engineering, procurement and construction of the fit-out of the system at its polyhalite project in Yorkshire, England.

The MTS fit-out scope includes the fit-out of the MTS conveyor, the maintenance railway, electrical and communications infrastructure, and all other services in the tunnel essential to the operation of the MTS.

Sirius said the price of the MTS fit-out was in line with the company’s capital re-estimate announced on September 6.

The MTS will carry the company’s mined polyhalite from 360 m underground at the Woodsmith mine site to the materials handling facility at Wilton, Teesside, on a 37 km underground conveyor system. The tunnel will be constructed by three tunnel boring machines and the conveyor system in the MTS will be designed to handle 20 Mt/y of throughput. It will also contain maintenance rail and services, including a 66 kV power feeder from Wilton International industrial complex.

More than 50% of the MTS fit-out price is on a fixed rate or lump-sum basis, with the remainder based upon estimated prices to be converted into fixed prices prior to completion of stage two financing. The proposed schedule for the MTS fit-out is in line with the company’s overall project schedule, Sirius said.

This is a significant step forward for the project, with Sirius saying it has now completed its procurement for the major construction packages related to the stage two senior debt financing process.

Chris Fraser, Managing Director and CEO of Sirius, said the company’s efforts were now focused on the successful execution of its financing plan to fully finance the construction of its polyhalite project.

As previously announced, the company expects the capital funding requirement of the project to be $3.4-$3.6 billion (previously $3bn), with a $3 billion senior debt financing being the appropriate level of debt.

Given the timing of completion of the final procurement contracts, final lender commitment letters are expected to be received in December and January. The company is targeting financial close of stage two financing in the March quarter.

Sirius awards more contracts for North Yorkshire polyhalite project as capital costs rise

Construction firm STRABAG and engineering group Jacobs have become the latest recipients of contracts for the Sirius Minerals’ owned North Yorkshire polyhalite project in the northeast of England.

STRABAG, which had already been awarded a design and build contract for the first drive of the mineral transport system (MTS) tunnel between Wilton and Lockwood Beck, near Teesside, has been contracted to construct drives two and three. Jacobs, meanwhile, has been given an engineer, procurement and construction contract for the materials handling facility (MHF) at Wilton.

These announcements came as Sirius updated its capital cost estimate for stage two of the project, which is expected to see the mine expand from 10 Mt/y of polyhalite to 20 Mt/y.

This has seen the stage two capital requirement go from $3 billion in November 2016 to $3.6 billion today.

The majority of the cost increase is associated with the MTS (pictured), which Sirius said reflected its own increased understanding of the “geotechnical characteristics of the strata within which the MTS will be excavated”.

This followed further ground investigation and seismic work that led to a refinement of the parameters set out in the geotechnical baseline report upon which the tunnelling contract was determined.

Chris Fraser, Managing Director and CEO of Sirius Minerals, said the cost increase reflected “an optimisation of the MTS tunnel design and a significantly improved risk allocation for Sirius to support the senior debt financing”.

The MTS cost increase is driven by a combination of the following factors:

  • Optimisation of the tunnel design including an increase in the planned internal diameter of the tunnel from 4.3 m to 4.9 m and an increase in lining thickness from 250 mm to 350 mm;
  • A decrease in advance rates as compared from 25 m/d to 17 m/d, and;
  • A commercial risk allocation which transfers construction and delivery risk to STRABAG.

The MTS includes a 37 km tunnel for a conveyor system to transport the polyhalite from the mine near Whitby to Wilton on Teesside for processing. STRABAG will construct the tunnel by using a Tunnel Boring Machine and the company expects to use a high-capacity conveyor belt system capable of transporting 20 Mt/y of polyhalite at 7.5 m/s.

The MHF will be constructed and managed by Jacobs’ UK subsidiary, with the EPC contract agreed on a target price basis, with financial incentives for completing the scope of work under budget, and financial penalties should completion be late or the cost be above the target price.

The plant has been scoped to include 7 Mt/y of granulated and 3 Mt/y of coarse product in its first phase of development but with a footprint for up to 20 Mt/y of granulated product.

Sirius said its procurement process for the project is nearing completion for the major packages and it is in the final stage of negotiations for the outstanding scopes of work.

Included in this is the MTS fit out, which includes the supply and installation of the MTS conveyor and the associated power supply, and the port facilities which includes construction of the outload circuit, wharf and product storage facility.

Sirius has identified STRABAG as its preferred contractor for the MTS fit out and is in advanced negotiations for provision of port facilities.

As the upfront capital for stage two of the project has increased, Sirius has developed a construction programme that defers the initial costs associated with the port facilities and has amended the scope of work to include temporary truck and train transportation of product from the storage facility at Wilton to the port.

“This enables the construction of the overland conveyor to be deferred until such time as it can be funded through operating cash flows, currently assumed to be 2025,” Sirius said.

While capital costs may have increased in this latest update, the company’s operating cost estimates have actually dropped from $32.6/t in stage one (10 Mt/y) to $29.4/t, and $27.6/t in stage two (20 Mt/y) to $27.4/t.

Sirius has already raised $1.2 billion for mine construction at the project, which is expected to produce first polyhalite in 2021, reach 10 Mt/y production in 2024, expand to 13 Mt/y in 2026 and grow further to 20 Mt/y in 2029.
