Vertex to Incorporate TOMRA Laser Sorter into the Reward Gold Plant – with Refurbishment and Build on Target

Vertex Minerals (ASX:VTX) (Vertex or the Company) is pleased to announce that Gekko has incorporated pre-concentration of gold ore into the flow sheet and plant design for the Hill End Project. This comprises the inclusion of a TOMRA ore sorter. Gekko will design and manufacture simple conveyances to and from the proposed ore sorting unit, with the ore unit comprising a separate module to the crushing and gravity recovery circuit.


  • Vertex identified that pre-concentration of ore using TOMRA Laser Sorter technology should have a significant impact on the sustainability and profitability of the mining operation at Reward.
  • Gekko has incorporated ore sorting into the Reward flow sheet and plant design being refurbished/built at their Ballarat factory.
  • By processing only high-grade ore, energy and water consumption are greatly reduced leading to lower operating costs and reduction in carbon footprint.
  • Importantly, preconcentration allows the rejection of barren crushed rock. This greatly reduces the mass of ore to the remaining process and greatly reduces the volume of process sand residue. The rejected material is transported back underground to fill the mined voids. This provides a significant cost advantage and has many ESG benefits.
  • 94kg of sample from the low-grade stockpile at Reward Gold Mine (Reward) was sorted. The following results are reported;
    • Head grade to Sorter weighted average grade (WAG) = 3.70 g/t gold,
    • Ore grade WAG after sorting = 16.22g/t gold (337.20% increase on grade),
    • Ore/waste split after sorting = 19.31kgs Ore vs 74.54kgs Waste (79% mass reduction),
    • Gold lost to waste fraction = 0.03grams/t (>90% efficiency)

Refer to VTX ASX Announcement 26th July 2024

  • Previous scoping test results from TOMRA suggested that the barren country rock that is mined with the gold bearing quartz veins can be efficiently detected and removed from mined material. This leads to significant increase in head grade reporting to the gravity section of the processing plant.
  • Refurbishment of the plant is well underway, and Vertex anticipates that the plant will be re-installed at Hill End later this year. The Company anticipates production will commence in January 2025.

Demobilisation of equipment from the Morningstar and Hill End mines has been completed, and refurbishment of this equipment is underway at Gekko’s factory in Ballarat.

The ore sorting technology can separate high-grade gold bearing quartz ore from the barren sedimentary country rock before it enters the processing stream. This significantly reduces the quantity of material that requires further processing to recover gold. Vertex believes that the application of ore sorting technology at Hill End can achieve more than a 50% reduction in the ore processing volume. Benefits include:

  • Reduction in energy consumption.
  • Reduction in water consumption.
  • Reduction in the process residue that requires dry stacking on surface.
  • Processing plant will only need to be run on a day shift basis.

Commenting on the results, Executive Chairman, Roger Jackson, said“We are very pleased with how Gekko have been able to integrate the Sorter into the Hill End Gravity plant. Further we are very thrilled to see the plant starting to take shape in the Gekko Ballarat factory. We are very much looking forward to its installation and commissioning later this year”.

Vertex Minerals Limited  Reward Gold Mine and Company Update

Vertex Minerals Limited Reward Gold Mine and Company Update

Perth, Australia (ABN Newswire) - Vertex Minerals Limited (ASX:VTX) (OTCMKTS:VTXXF) is pleased to announce a further update on the Reward Gold mine start up.

HIGHLIGHTS

- All major components are now installed and fitted at the Reward Gold Mine Gravity Plant.

- Electrical fit out is well underway.

- Piping and water reticulation is ongoing.

- Tails lines are being laid to the dry sand stack location.

- Plant power up is planned for mid-December.

- General Manager and other key personnel have commenced employment.

- Ore Sorter structure is under construction and will be installed in January

- The plant will be commissioned on stockpiles located at the plant prior to the Ore Sorter installation.

- Road infrastructure upgraded.

- Portal entry and ore handling area refurbished and expanded.

- Vertex on track for January commissioning of the plant.

Mobilisation of the Gravity Plant from Ballart to site commenced earlier this month (as announced 13 November 2024), with all major components now onsite, installed and fitted at the Gravity Plant. Fitout of ancillary services (including electrical and water) is well underway, with completion and initial powering-up scheduled for mid-December 2024.

All Civil Works for this stage, including the upgrading and refurbishment of Road Infrastructure, portal entry and the ore handling area are also complete.

Ore Sorter and Forward Plan

Compelling results from Ore Sorting testwork (including a 337% increase in grade and 79% mass reduction) as announced on 25th July 2024, resulted in a decision to incorporate pre-concentration into the flow sheet and design for the Hill End project (as announced 11 September 2024). Construction of the Ore Sorter structure has commenced, with installation expected in January 2025. Installation of the Ore Sorter is not expected to delay plant commissioning, with initial processing of existing stockpiles located at the plant location to commence prior to installation and commissioning of the Ore Sorter.

Corporate and Financial

On 7 November 2024, Shareholders voted to approve the second tranche of the Company's 2-tranche share placement announced in mid-August 2024. All funds for the second tranche have been received and allotment is expected shortly.

The Company's Annual General Meeting (AGM) is scheduled for 29 November 2024 and resolutions include approval for the conversion of loan funds received under the capital-raising announced in October 2024. Various option issue approvals were granted in the 7 November Meeting and are being sought at the AGM and a prospectus for the issue of those options is being prepared.

On 27 May 2024 the Company announced that it had signed a terms sheet with Ocean Partners for a US$10M Prepayment Facility, subject to conditions precedent. Following on from the revised mine design and Gravity plant flow sheet, because of the decision to utilise an ore sorter, the capital expenditure required to develop the mine was significantly lowered. A facility of this size is no longer expected to be required by the Company and the parties have agreed that the proposed arrangement will not be completed, with no penalty to the Company. The Company is in negotiations with several parties in relation to a significantly smaller debt or prepayment facility.

Commenting on the progress, Vertex Executive Chairman Roger Jackson said: "We are very excited by the progress that has been made with the Gravity Gold plant installation at our mine ready Gold project.

The installation is well ahead of the time we had scheduled, which has helped recover the time lost due to weather with the civil construction. We are hopeful we can now power the plant up for testing in just a few weeks. We then can commission the plant with the gold ore stockpiles we have sitting at the plant.

I would commend Gekko and our Hill End team for their efforts with this installation."
