Key Points:
- REZ has received approval to commence a trial vat leach and bulk sample program at the East Menzies Gold Project.
- The Maranoa deposit will provide the ore for the trial, with an initial 5,000 tonnes to be processed and the first gold pour expected within two months.
- REZ’s shares rose by 8% following the approval, reflecting investor confidence in the project’s potential.
Resources & Energy Group Limited (ASX:REZ) has secured a key approval from the Western Australian Department of Mines, Industry Regulation and Safety (DMIRS) to launch a trial vat leach and bulk sample program at its East Menzies Gold Project. The approval marks a significant milestone in REZ's development strategy, with the Maranoa deposit providing the ore material needed for the trial. This initial phase of the project will pave the way for the company’s first gold pour, anticipated to occur within the next two months.
The trial involves processing approximately 5,000 tonnes of ore from the Maranoa site through a vat leach method. The ore is expected to have a diluted grade of around 4.6 grams per tonne (g/t) of gold (Au). Should the results from this initial testing phase prove successful, it will serve as the foundation for scaling up the operations to treat additional ore resources across the East Menzies Gold Project. Ultimately, REZ has a longer-term target of producing up to 51,000 ounces of gold from the region.
A Major Step for the East Menzies Gold Project
The East Menzies Gold Project has emerged as a core asset for REZ, with its Maranoa deposit playing a pivotal role in the company’s early-stage production efforts. The successful commencement of the vat leach testing program represents a significant opportunity for the company to optimize its extraction process and begin generating revenue. The trial vat leach will be a critical test of the project’s viability and will also signal the start of gold production, which REZ aims to achieve within two months.
The vat leaching process is a cost-effective method of processing gold ore, particularly for smaller projects or trial phases. By utilizing this technique, REZ aims to minimize upfront costs while still generating valuable data and, potentially, initial income from gold production. This revenue will, in turn, be reinvested into ongoing exploration activities to identify and develop additional resource opportunities at East Menzies.
In addition to the initial 5,000 tonnes of ore, the company has a broader plan to process 51,000 ounces of gold, underscoring the long-term production potential of the project. With this pipeline of projects, REZ anticipates sustaining production, allowing it to continue its growth trajectory and reinvest in exploration and expansion.
Geological Insights at Maranoa
The Maranoa deposit is characterized by its unique geological makeup. The ore is hosted in banded quartz-amphibolite rocks, with minor sulphides embedded within a broader envelope of sheared metabasalt, which also displays proximal biotite alteration. The quartz veins within the deposit feature centimetre-scale banding and are associated with coarse plagioclase and carbonate. Minor amounts of ilmenite, chalcopyrite, and pyrrhotite are also present, adding to the complexity and richness of the ore.
This geological profile suggests that the Maranoa deposit is part of a broader mineralized structure with diffuse shears, which appear to be aligned with the regional folding of the area. These findings further highlight the potential for ongoing exploration and discovery within the broader East Menzies region, as REZ seeks to unlock additional mineral resources.
Management and Market Reaction
REZ Group Managing Director J. Daniel Moore emphasized the importance of this latest approval, noting that it brings the company closer to achieving its first gold pour and realizing the full potential of the East Menzies Gold Project. Moore stated, “This crucial approval to commence mining operations at East Menzies – at the Maranoa deposit – represents a significant opportunity to advance our vat leach testing and achieve our first gold pour of this campaign. This is a major milestone for the company and our shareholders.”
The market responded positively to the news, with REZ’s share price rising by 8% at the time of writing on October 8, 2024. Investors are clearly optimistic about the company’s progress and the potential of the East Menzies Gold Project, especially as the trial phase approaches its first tangible milestone: the gold pour.
Looking Ahead
The commencement of the vat leach program at East Menzies represents just the beginning of REZ’s broader ambitions in the region. With the Maranoa deposit serving as the catalyst for early-stage production, the company plans to leverage its initial success to fund further exploration and expand its resource base. The long-term production goal of 51,000 ounces of gold signals REZ’s confidence in the project’s scalability.
