In the press release, the Wings target is similiar to Atlantic Gold's Toukoy (Moose Rivers mine). This is among the most profitable mine in the world. Probably why it was bought out a year ago. I came across this article on kitco from 2019.

A good example is Nova Scotia, where a long history of small-scale high-grade underground mines never turned a profit. No one thought it was possible, but Atlantic Gold (TSX-V:AGB) has shown that open-pittable, disseminated gold is not only possible but a highly profitable business in Atlantic Canada. Its flagship Moose River Consolidated (MRC) project - the first open-pit gold mine in Nova Scotia - opened just over a year ago.
The mine plan entails a very low strip ratio (0.76:1), which means every there is very little waste ore to help keep costs low and gold production high. At full build-out AGB expects to produce about 200,000 ounces a year.
At AISC of $528 an ounce at today’s gold price of $1,250/oz, Atlantic Gold’s profit margin is a remarkable $717/oz. Unlike the gold majors at the top of the mining cycle, whose mantra was “more production”, AGB is running the MRC mine like a business - keeping costs in line with revenues. Moose River generated profits of $6 million in the third quarter.
Along with a low strip ratio, the other factors helping Atlantic Gold control costs are: the mine’s close proximity to labor, suppliers and the airport; a 1.5 g/t grade; and ease of gold recovery. In fact, Atlantic Gold is currently the lowest cost gold producer. The highest-cost mid-tiers have AISCs of between $1,200 and $1,300/oz.
Furthermore, As at 25 March 2019, the Atlantic Gold operation had a combined estimated 1.9 million ounces of gold in reserves at a grade of 1.12 grams per tonne. For full details, refer to the compliance documents at
