Resources and Energy Group (ASX:REZ): Maiden Mineral Resource Established at Gigante Grande East Menzies Gold Project, WA

Resources and Energy Group (ASX:REZ)

• Data review of a 6km long gold mineralised system at Gigante Grande reveals initial Gigante Grande Maiden Gold Resource
• Maiden Inferred Mineral Resource of 1.39 Mt @ 0.91 g/t Au for 40,700 oz (JORC 2012)
• Mineralisation remains open to the northwest and at depth, highlighting a pathway for potential further resource growth
• This maiden resource provides confidence in the prospective economics of Gigante Grande and includes 33,500oz at 1.02g/t Au from the lower saprolite supergene, and in situ granite-hosted mineralisation
• The Inferred Resource is constrained within an optimised 700m long, 300m wide and 120m deep open pit shell generated under the JORC 2012 reasonable prospects assessment
• The majority of the inferred resource is defined by 80m spaced drill sections with a limited number of holes testing for in situ mineralisation below lower saprolite supergene mineralisation

Resources & Energy Group Limited (ASX: REZ) (REZ or the Company) is pleased to advise that ERM Consultants completed the maiden Inferred Mineral Resource Estimate at Gigante Grande, which consists of 1.39M tonnes at 0.91g/t Au for 40,700oz (JORC 2012). Gigante Grande complements existing high-grade prospects at East Menzies, giving REZ both scale and grade pathways across its project portfolio.

REZ initiated the resource evaluation to provide confidence that the existing areas of lightly tested mineralisation at Gigante Grande would meet economic benchmarks. This confirmation of the inferred classification, and the scale of the pit shell generated, provides REZ with optimism that an economic large-volume low-grade resource can be discovered at Gigante Grande.

The evaluation of the economics at Gigante Grande forms an essential part of the East Menzies Project data review. It will assist REZ in determining the forward exploration strategy and where to find the best value for the exploration budget.
