Precious metals explorer Oar Resources (ASX: OAR) has commenced a maiden diamond drilling program at its high-grade Douglas Canyon gold-silver project in the prolific Walker Lane district of southern Nevada.
The 1,000 metre campaign will comprise an initial two holes targeting known near-surface mineralised structures.
An additional two holes based on first pass observations will be positioned to test down-dip depth extensions.
Drilling will target outcropping high-grade gold-silver epithermal veins, where previously-reported surface outcrop samples include 18.0 grams per tonne gold and 398g/t silver; 16.2g/t gold and 495g/t silver; and 14g/t gold and 423g/t silver.
General manager (geology) Tony Greenaway said the maiden program would focus on standout targets within the Douglas Canyon project area.
“Based on exceptional high-grade results delivered in our outcrop sampling program as well as the project’s location in the prolific Walker Lane district, we see Douglas Canyon as a promising gold exploration opportunity,” he said.
“We are excited by the potential of [our identified targets] to deliver some strong gold intersections.”
Douglas Canyon is located in the Camp David/Mina district which is host to numerous high-grade, gold-silver epithermal projects.
The area immediately surrounding Oar’s acreage has become a major focus of exploration for companies including Fortitude Gold Corporation which commenced production in 2019 at the Isabella Pearl gold mine, 24km to the northwest of Douglas Canyon.
Isabella Pearl has an estimated reserve of 1.28 million tonnes at 3.88g/t gold for 159,000 ounces, with Fortitude targeting an annual gold production of up to 45,000oz.
Fortitude also owns the nearby Mina gold project (with drill intersections of 15.24m at 3.86g/t gold from surface) and the East Camp Douglas project (22.86m at 13.55g/t gold from 4.6m).
Gold mineralisation in the region is hosted in northwest-trending, shear-hosted epithermal quartz veins similar to those mapped from surface at Douglas Canyon.
The Walker Lane district is believed to host several million-ounce deposits and has been ranked the third best mining jurisdiction in the world.
