Evolution Mining studying open-pit, underground expansion options at Cowal

Evolution Mining says it is embarking on a prefeasibility study to further expand its Cowal open-pit mine as part of a plan to build towards 350,000 oz/y of sustainable, reliable, low-cost gold production from the New South Wales operation.

Currently on the E42 stage H cutback, Evolution said during a recent site visit that there is potential to further the life of the open pit by accessing feed from the E41 and E46 satellite pits. The study looking into a possible expansion is due later this year, with the company saying it could provide long-term base load ore feed for the operation.

The mine produced 262,000 ounces in Evolution’s 2020 financial year.

The Stage H cutback the company is currently pursuing is expected to see increased ore volumes and grade mined in the first six months of this year, with the strip ratio to fall below 1:1 in its 2023 financial year, Evolution said. It also says an equipment strategy review is underway, with opportunities to “rationalise fleet” with reduced re-handling.

The haulage and loading fleet at Cowal currently consists of 20 Cat 789C dump trucks, three Cat 785C trucks, four excavators (one Liebherr 9400, one Liebherr 994B, one Liebherr 9200 and one Hitachi EX1200), plus three Cat 992G wheel loaders. It also has six hired Epiroc SmartROC surface drills at the operation, one Drill Rigs Australia GC600 drill rig, five Cat D10T tracked dozers and one Cat 834H wheel dozer.

The open-pit expansion is only part of the expansion story at Cowal, with a feasibility study underway on an underground operation. This is factoring in 3 Moz of resources and 1 Moz of reserves, with high-grade orebodies open at depth, the company says.

A second decline (Galway) is due to be developed at Cowal this year, with diamond drilling set to commence next month. The 14,300 m of planned drilling will, the company says, help confirm optimal grade control parameters and convert resources to reserves.

Evolution Mining also has a permit to increase processing capacity at Cowal to 9.8 Mt/y, with near-term incremental improvements targeting a circa-9 Mt/y rate.

The process flowsheet at Cowal includes primary crushing with a Metso Outotec 54-75 Superior MK-II gyratory, grinding with an FLSmidth 36 ft (11 m) x 20.5 ft (6.2 m) SAG mill and FLSmidth 22 ft x 36.5 ft ball mill, and screening with Schenck and Delkor screens. Sandvik H6800 hydroconecone crushers, Metso Outotec flotation cells, a Metso Outotec Vertimill, and Metso Outotec stirred media detritors also feature.

Evolution also said it is testing technology that uses glycine and cyanide during the cyanidation process of gold ore at Cowal for potential significant cost savings and environmental benefits.

Lab trials with the GlyCat™ technology from Australia-based Mining and Process Solutions have been completed successfully, it said, with the next phase being pilot plant trials to assess variability tests and long-term environmental impacts.

Metso Outotec gets to the core of hydrocyclone operation

To help ensure continuously optimal hydrocyclone operation, Metso Outotec is introducing CycloneSense™, a smart measurement system that, it says, provides direct, continuous and reliable online monitoring of the hydrocyclone air core.

“In order to optimise the process, hydrocyclones should be run so that the fraction of water returned to grinding is the smallest amount possible,” DSc., Professor Emeritus, Kari Heiskanen, a well-known expert in the field and the author of the book ‘Particle Classification’ says. “In order to do that, you need to know when you are approaching the limit of your hydrocyclone’s coarse discharge rate to avoid going too far and ending up with problems, such as roping,”

He continues: “CycloneSense allows you to see what is happening inside the hydrocyclone and helps to push the limits of the process.”

CycloneSense allows operators to visualise the performance inside the cyclone, facilitating continuous online measurement of the cyclone’s air core shape, size and location based on process tomography, thus helping to find and maintain the optimal operating point for the hydrocyclone, Metso Outotec says. In addition, the measurement system helps to detect and prevent potential problem situations, such as roping, where the slurry is not properly separated and, instead, some of the larger particles are sent to the overflow and directly to the next stage of processing.

Combining CycloneSense with the Metso Outotec PSI® particle size analyser allows easy optimisation of the cyclone cluster and grinding circuit, according to the company. Metso Outotec’s ACT Cyclone Control and Grinding Optimization is designed to take full advantage of the measurement data and to provide significant and continuous benefits to customers.

The CycloneSense measurement system is available for new Metso Outotec hydrocyclones and any existing hydrocyclone installations. As an optional service, Metso Outotec also provides Life Cycle Services with remote monitoring.

Roxgold lays Séguéla groundwork with Metso Outotec, Lycopodium contract awards

Roxgold says it has awarded a SAG mill order for the Séguéla gold project in Côte d’Ivoire to Metso Outotec as part of its efforts to advance the project through to construction in the coming months.

The move comes ahead of the release of feasibility study on the project next month, which will build on a 2020 preliminary economic assessment (PEA) that outlined an operation capable of delivering over 100,000 oz/y of gold over eight years at average all-in sustaining costs of $749/oz. This study also incorporated a single stage primary crush/SAG milling comminution circuit with 1.25 Mt/y throughput.

At the same time as selecting Metso Outotec for the SAG mill contract, Roxgold has awarded preferred contractor status to Lycopodium Minerals Pty Ltd and is currently negotiating the engineering, procurement, and construction (EPC) agreement with the company for the 1.25 Mt/y carbon-in-leach processing facility and other supporting infrastructure to be constructed at Séguéla.

The fixed price agreement increases confidence in the total capital cost for the project, as it is by far the largest scope at Séguéla, Roxgold said.

“With this agreement in the final stages of negotiation and several other key scopes now tendered and priced, approximately 65% of the pre-production capital estimate has now been fixed or finalised,” the company added. “This level of detail provides increased confidence around the pre-production capital estimate, which is expected to be in-line with the previous estimate of $142 million, as outlined in the PEA.”

In terms of progressing work on long-lead time items, Roxgold said it had awarded the plant site bulk earthworks tender, with a contract expected to be executed and works commenced in the June quarter to support the project critical path.

The company has continued to advance its early works program at site including upgrading of the site access road and construction of the accommodation village. Contracts were awarded for camp bulk earthworks and camp construction, with first concrete poured last month, it said.

Surveying has been completed for the 33 kV and 90 kV power lines to tie into the existing 90 kV transmission line running across the property, which is connected to the 225 kV ring main system around the country. These early work activities will enable a rapid ramp up to full construction upon completion of the feasibility study and mine financing in the June quarter of this year.

Roxgold says it has undertaken a competitive tender process and has conducted a detailed assessment of the contract mining proposals received. It is currently completing diligence on the shortlisted parties and plans to award the mining contract later this year to allow for contractor mobilisation, site establishment,and commencement of pre-production mining early next year.

John Dorward, President and Chief Executive Officer, said: “The Séguéla project has rapidly become a cornerstone asset for Roxgold, and we believe that the project will provide significant value to all our stakeholders.

“The feasibility study is on track to be announced in the second (June) quarter, which we believe will demonstrate the ongoing evolution of the Séguéla PEA with an enhanced mine life and project economics with the inclusion of the high-grade Koula deposit into the mine plan.”

SIMPEC awarded significant Cloudbreak crusher contract from Fortescue

SIMPEC’s relationship with Fortescue Metals Group continues to strengthen, with the engineering contractor set to replace two Metso Outotec Nordberg® C160 jaw crushers at the miner’s Cloudbreak iron ore operation in the Pilbara of Western Australia.

The WestStar Industrial Ltd subsidiary’s new contract for the Hopper 5 Jaw Crusher Replacement project is the first win directly from Fortescue but is far from the first time the company has stepped on site at one of its mines. SIMPEC has previously carried out work on its operations after being subcontracted by the likes of Central Systems, Energy Power Systems, ATCO and others.

The scope of the jaw crusher contract includes removal of all structural and mechanical items required to access the jaw crushers, followed by reinstatement on completion of the change out. It also includes maintenance works and modifications to the existing Hopper 5 hoppers, chutes and screens, SIMPEC said.

Worth A$2.1 million ($1.6 million), the vertical contract has commenced immediately, with works expected to be completed in April.

SIMPEC Managing Director, Mark Dimasi, said: “It has been a long-term goal of SIMPEC to work directly for Fortescue and to break into the field of sustaining capital works. By building our sustaining capital portfolio, SIMPEC aims to achieve a more stable cash flow as well as provide continuity for our workforce.

“This is a very proud moment for the team, and we look forward to successful completion of this project and what we hope will be a long-term relationship with Fortescue.”

Metso Outotec takes next sustainability steps with Planet Positive

Metso Outotec has introduced a new approach to sustainability that, it says, covers the environmental, social and financial aspects of the topic area.

Its ‘Planet Positive’ efforts enforce the company’s purpose to enable sustainable modern life, the company says, building on Metso Outotec’s commitments to limit global warming to 1.5°C, with targets validated by the Science Based Targets initiative.

To serve customers’ sustainability needs and to increase the size of its ecological handprint, Metso Outotec focuses on further growing its sustainable offering. The Planet Positive portfolio focuses on the most environmentally efficient technologies – of which there are more than 100 – in the company’s current portfolio, responding to the sustainability requirements of its customers in the aggregates, mining and metals refining industries. The customer requirements relate to energy or water efficiency, reduction of emissions, circularity and safety, it says.

Correspondingly, Metso Outotec focuses on minimising the environmental impact of its own operations and supply chain to diminish its ecological footprint. Already today, Metso Outotec’s handprint is significantly bigger than its footprint, it says.

Piia Karhu, SVP, Business Development at Metso Outotec, said: “We have a wide Planet Positive offering available for our customers and, with strong R&D focus, we continue to strengthen our sustainable offering for aggregates, mining and metals refining industries. We also have high targets for sustainability in our own operations and supply chain. There is a growing demand in our industry for environmentally efficient solutions.”
