Explaining Mining Mathematix
Any smart chaps care to explain how these mining metricss work here's an example from my favourite co. Aurcana...
"This is a significant acquisition for Aurcana as the 800 tonne per day La Negra mine and mill have been well maintained and the "skarn-hosted" polymetallic deposit has historically reported grades of approximately 160 grams/tonne silver, 2.83% zinc, 0.94% copper and 0.91% lead, contained in approximately 1.2 million tonnes."
"The exploration potential at La Negra is considered to be very good, both around existing ore zones and also at depth. Penoles developed a very detailed exploration model outlining potential blocks, location and number of holes to be drilled and a budget. In the La Negra district a general metal zonation has been recognized whereby lead -- zinc rich "manto" type bodies overlie silver rich lead -- zinc "chimney" type bodies. At greater depth the copper content increases significantly as seen on the Cristo Rey 2 level where stopes have historically reported grades of up to 353 grams/tonne silver, 5.69% copper and 1.26% zinc. Penoles reported diamond drilling results from 90 metres below the Cristo Rey 2 stope that graded 323 grams/tonne silver, 5.79% copper and 2.37% zinc over a width of 7.8 metres. Readers are however cautioned that this potential grade is an estimate and further due diligence and work is required by Aurcana to verify the grade and widths."
