Mine Valuations!
Alluvial Gold (nugget) prospecting/Creation of Bankable Geological reports, site visit and physical works for mine valuation.
We highly recommend this SDC 2300 MineLab metal detector for this purpose. This and the parent GPZ7000 detector. If we are picking nuggets weighing 0.05-0.1g, it is more economical and efficient to instead use a wash plant than to use a smaller detector, these two detectors are the proven economical threshold. We use the detector for ore grade quality control, pick 3 gold pieces, then load and haul that heap to the plant. Ensures, we pack only money.
How much gold resource does your site hold? We do bulk sampling by pitting of the pay dirt to the limiting bedrock. If the nuggets are >0.05g in size, the detector alone suffices to get per ton values. For smaller nuggets, this rubber mat would equally suffice. Larger plants are just variants and more efficient versions of the rubber mat. Extractive principle is the same.
Below is a practical mine valuation exercise: Sampled layer thickness = 0.5 meters, your riverbed length section= 1000 meters (1km), riverbed width = 5 meters; Gravel bulk density = 1.5ton/meter cube. Gold Ore reserve Volume =2500, tonnage 1.5x2500 = 3750 ton. Verified gold ore grade = 3g/ton
Then gross mine valuation = 3750x3 = 11,250g or 11 kilos of gold. No unnecessary complexity and theories. Simple, practical, straight forward, guaranteed and verified✔️
Simplicity and excellence. Abene Gold
