You don't get it. DGRI is claiming to be a "real" mining company, yet has done no exploration work on their Nicaraguan "gold mine" before buying equipment? You cite the example of the placer mine in Uganda - my understanding is that the mine in Nicaragua is supposed to be a hard rock mine. You don't "shovel dirt and pan out the gold" to explore a hard rock mine. You map the geology, you sample the outcrops, and you drill. It takes months, sometimes years to get this stage done and from what I can tell, they have not even started. And then you take the data and prepare a feasibility study to see if it makes sense economically to mine the deposit. No evidence whatsoever that any of this has occurred.
A few high-graded samples off of ore piles, and a single sample sent to a dubious metallurgical lab say nothing about the ore grade, tonnage, or other factors that go into the equation. Appears to be a total sham in my opinion.
