VRX Silica Limited has commenced a three-day drilling program at its 100%-owned Muchea Silica Sand Project (Muchea), located approximately 50km north of Perth, Western Australia. A tractor-mounted vacuum drill rig will drill a minimum of 100 holes to produce a five-tonne sample to be used in an additional pilot plant metallurgical test work program. The program will determine if selective mining and processing of the differentiated layers, identified in previous test work, can produce a higher-purity product, therefore significantly enhancing Muchea's project economics.

The company will also generate further samples for testing following overwhelming interest from potential offtake partners. Muchea Cleared Track: The drill program at Muchea will be undertaken along existing cleared tracks, with an approved Program of Work from the Department of Mines, Industry Regulation and Safety. VRX has previously undertaken an Aboriginal Heritage survey to clear the proposed program area.

Representatives of the Whadjuk People will accompany the drill crew. In March 20191, VRX conducted a drilling program of 57 50m-spaced air core holes. This drilling resulted in an updated Mineral Resource Estimate2 of 208 Million Tonnes (29Mt Indicated & 179 Mt Inferred) and a maiden Probable Ore Reserve3 of 18.7 Million Tonnes.

Analysis of the 2019 Resource estimates indicated that ore within 5m of the surface was consistently lower in contaminants than deeper material. Prior test work on the full column of ore resulted in a very high-grade silica sand product. The drill program announced will delineate the variation in these layers.

Muchea Drill Rig: Separate bulk metallurgical testing will be undertaken on composites representing these layers to determine if a higher-purity product can be produced by selective mining and processing of the differentiated layers. Near-surface, lower-contaminant ore may have the potential to produce a higher-value product, further enhancing the economics of this world- class silica sand project. The drill program will be contained within the current Mineral Resource Estimate area.
