Initial metallurgical results support Golden Dawn Minerals’ (TSXV:GOM) plan to put a southeastern British Columbia mine and mill back into production. A 16-kilogram composite sample from the May Mac mine underwent gravity and flotation at the company’s Greenwood mill, 15 kilometres away, with 98% recovery for gold and 97.7% for silver. Preliminary results suggest no major modifications to the mill would be necessary to process May Mac feed.
The past producer comprises one of several former mines proximal to the mill that Golden Dawn endeavours to re-open.
“Flotation cleaning will now be tested in order to make a higher-grade concentrate for sale,” the company stated. “Optionally, cyanide leaching results after 48 hours’ retention indicate approximately half the silver was recovered, and with a gold recovery of 90%.”
Meanwhile underground drilling continues at May Mac, with surface drilling planned for next month. The company has permitting underway to extend the mine’s #7 level for a bulk sample of up to 10,000 tonnes for processing at the Greenwood mill. Plans also call for a maiden resource this year. Earlier this month the company released the last of 19 holes from last winter’s program.
With a de-watering permit now in process for the nearby Lexington project, Golden Dawn hopes to begin trial mining in Q3 or Q4. The past producer has 96,300 gold-equivalent ounces measured and indicated, along with 2,300 ounces inferred at a 3.5 g/t gold-equivalent cutoff.
Included in the 2017 agenda is surface drilling at Golden Crown, which currently hosts 62,500 gold-equivalent ounces indicated and 13,100 ounces inferred, also using a 3.5 g/t gold-equivalent cutoff.
Golden Dawn has a modest program of geophysics in store for the KRR property, an 11,000-hectare package of 29 historic mines and 40 significant showings. The company announced a 43-101 on the recent acquisition in January.
With a final tranche of US$1 million now in hand, the company has collected the full US$4-million advance from a gold purchase agreement with RIVI Capital LLC.
Golden Dawn’s Greenwood camp portfolio lies about 500 kilometres east of Vancouver.
