WR1 General Discussion, page-28718

Some very interesting points made by @neometals on the PMT board, providing further data and perspective on the Winsome/Patriot discussion that has taken over both boards (I am a shareholder in both companies, plus Azimut, south of Adina). I have been trying to wrap my mind around what an open pit mine on the Adina property would look like, so found the discussion really helpful. Is there anyone on this board who could share how the most economic open pit could be designed? Trying to educate myself in a basic way on mining enginering....

"Stacked pegmatites present additional challenges and much higher opex (much higher waste/ore ratios). Below is the Adina deposit from the MRE. Half of the resource is in the top pegmatite (main zone) and half the resource is on the lower pegmatite (footwall zone), these zones are separated by ~100-150m depth. I challenge WR1 posters to draw an open pit shell around the two ore bodies, since comparisons are being made on the suggestion that WR1 will mine their current 59 Mt resource. Waste/ore ratios will be significantly higher at Adina, no getting around that. They could potentially make a small open pit and mine the main zone at shallow depths, thus the resource is <25 Mt of mineable material (perhaps attempt underground mining for the footwall zone). Or make a larger open pit to tap the main and footwall zones, but there will be a ton of waste they must process. Considerations they are no doubt thinking about on an opex basis. The deeper thinner slivers of the main and footwall zones that are steeply dipping will likely not be mined."
