Underground refurbishment, equipment maintenance, engineering studies and permitting bring the Lexington mine closer to renewed operations.
Channel sample results from the face of previous underground workings auger well for plans to re-start southern British Columbia’s Lexington mine, Golden Dawn Minerals TSXV:GOM stated June 11. The company released several dozen assays from a campaign that’s collected 339 samples so far. Four of the best composite results showed:
- - 30.18 g/t gold and 4.93% copper (37.57 g/t gold-equivalent) over 1.8 metres
- - 26.67 g/t gold and 1.77% copper (29.33 g/t gold-equivalent) over 2.3 metres
- - 13.41 g/t gold and 2.08% copper (16.54 g/t gold-equivalent) over 3.9 metres
- - 17.04 g/t gold and 3.42% copper (22.16 g/t gold-equivalent) over 2.6 metres
The grades bolster confidence in the 2016 resource and would help reduce dilution of mill feed during trial mining, anticipated to begin later this year, the company stated. Having produced a PEA for its Greenwood properties last year, Golden Dawn hopes to re-start some of the former mines without de-risking at the feasibility level. The 15,400-hectare portfolio includes 31 historic mines. Processing would take place at the company’s nearby Greenwood mill, a 212-tpd facility that’s expandable to 400 tpd.
Using a base case cutoff of 3.5 g/t gold-equivalent, Lexington’s resource shows:
- - measured: 58,000 tonnes averaging 6.98 g/t gold and 1.1% copper (8.63 g/t gold-equivalent) for 16,100 gold-equivalent ounces
- - indicated: 314,000 tonnes averaging 6.38 g/t gold and 1.04% copper (7.94 g/t gold-equivalent) for 80,200 gold-equivalent ounces
- - inferred: 12,000 tonnes averaging 4.42 g/t gold and 1.03% copper (5.96 g/t gold-equivalent) for 2,300 gold-equivalent ounces
Under a previous operator between April and December 2008, the mine produced 5,486 ounces of gold, 3,247 ounces of silver and 860,259 pounds of copper.
Recent work suggests possible extensions to the northwest of two potential parallel mineralized zones near Lexington’s Main zone. Golden Dawn also sees a “one-kilometre-long trend of favourable host rocks” stretching from Lexington into the former Lone Star mine just across the border in Washington state. “The favourable stratigraphy also extends over three kilometres to the northwest through the historic Lexington, Mable and Number 7 mines, where minimal past exploration drilling was done,” the company stated. Previous sampling shows further potential around the nearby City of Paris former mine, Golden Dawn added.
The company continues its extensive work on Lexington’s mine infrastructure, equipment, engineering studies and permitting.
Earlier this month Golden Dawn closed a $734,700 first tranche of a private placement offered up to $5.4 million. Last month the company issued shares to repay $160,339 in debt to Lind Asset Management.
