Enegex (ASX: ENX) has secured new gold targets to strengthen its strategic tenure position in the West Yilgarn metals province of Western Australia. The exploration licence applications are consistent with its aim to secure and test high-value gold and copper targets in an area where it has considerable operating experience.
Rocky Ridge Gold Prospect
At the company’s large Perenjori Project, a new exploration licence application covers the Rocky Ridge gold prospect, across an area of significant gold anomalism first identified by a subsidiary of Dominion Mining during 2007-2010, ahead of its takeover by Kingsgate Mining Ltd in 2010.
Dominion carried out widespread regional sampling throughout the wheatbelt of WA, and Rocky Ridge was a strong gold target to emerge from this work.
Rocky Ridge is situated on the central and western part of a curved aeromagnetic and gravity trend extending more than 20km and is defined by auger gold anomalism over 6.5km of strike. Gold grades commonly exceed 100ppb and are contourable over wide areas at >20ppb Au. The prospect represents a significant regional gold anomaly.
Dominion completed detailed auger sampling, a grid of shallow RAB and aircore drilling, and eight RC holes. Drilling focused on a 1.5km portion of the auger anomaly, outlining significant and widespread near surface gold underlain by zones of >0.20g/t Au anomalism in bedrock
Much of the Dominion RAB and aircore drilling was shallow (average hole depth 29m), reflecting a stripped weathering profile. Despite limited depth penetration this work returned drill results to 7m @ 2.52g/t Au EOH, 7m @ 1.14g/t Au EOH and 6m @ 0.98g/t Au indicating potential for commercial grades, and several traverses have consecutive drillholes ending in anomalous gold.
Since 2010 the area has been held and explored by a private company. Information on that stage of work will be compiled when it becomes available on Open File at the Geological Survey of WA (GSWA).
The orientation and style of mineralised structures remains to be determined, but the wide distribution of near-surface and oxide gold mineralisation points to exploration potential. Enegex said it sees an excellent opportunity to locate new and stronger bedrock gold mineralisation along the broader Rocky Ridge anomalous trend and will undertake detailed data compilation and on-ground geological work to firm-up future drill targets
Three Springs
The company has also secured a large new exploration licence application over a series of aeromagnetic features interpreted to represent folded greenstone and gneiss. The area is largely unexplored for gold besides a local auger sampling grid designed for nickel-copper- PGE exploration. Importantly this grid was also assayed for gold and returned zones of raised anomalism aligned with aeromagnetic features, and spot results to 151ppb Au. Anomalism is open to the edge of sampling in several locations, pointing to immediate follow-up potential.
The remaining portions of the tenement appear to be underlain by similar geology and therefore warrants field reconnaissance and first-pass geochemical sampling. This generally comprises soil or auger samples collected alongside access tracks and fence lines.
