Aurvista Gold adds greenfields exploration to resource expansion at Abitibi project

by Greg Klein | September 12, 2017

Successful financing doesn’t rule out cautious spending for Aurvista Gold TSXV:AVA. Having raised $10.1 million in July, the company spent the summer reconsidering the Douay project’s strategy. Working with Aurvista’s geological consultants, a newly appointed technical advisory committee developed an approach incorporating both brownfields and greenfields exploration for the recently expanded 33,170-hectare property on Abitibi’s Casa Berardi deformation zone. Work continues on sampling, re-logging previous core, and reviewing geological, geochemical and geophysical data.

Aurvista has another winter drill
program slated for this year.

To cut helicopter-borne costs, diamond drilling has been deferred to winter. But the committee also recommended a property-scale reverse circulation program “or similar top-of-bedrock sampling program to provide critically important geochemical data,” Aurvista stated.

Douay’s brownfields area hosts two types of gold mineralization, the company added. Seven zones from both areas contributed to last April’s resource update with an inferred total of 83.33 million tonnes averaging 1.05 g/t for 2.81 million gold ounces at a 0.5 g/t cutoff.

Higher grades hosted in altered mafic volcanics can be found in the Douay West zone, with its inferred 4.47 million tonnes averaging 2.36 g/t. Altered porphyritic rocks offer lower grades, such as the Porphyry zone, with its inferred 72.16 million tonnes averaging 0.96 g/t.

The resource remains open along strike and plunge, providing excellent expansion potential, the company emphasized. But Aurvista also sees potential in Douay’s relatively unexplored area for VMS, mafic, porphyry and other styles of mineralization.

Indications of Douay’s future might come from the past as well. A huge relogging program has been underway to simplify the project’s geological model. Still to be completed are about 27,000 metres out of a 220,000-metre archive dating to 1976. Oddly enough, a lot of that core was never assayed for gold. The team intends to prepare about 18,000 samples for lab analysis.

Once targets have been refined, Aurvista plans to spend the bulk of its treasury on diamond drilling both greenfields and brownfields targets, with the rigs resuming their work this winter.

In July the company released final assays from Douay’s previous 59-hole, 23,965-metre program.
