Compressed Air Magazine, Vol. 26 : August, 1921 (Classic Reprint)
Excerpt from Compressed Air Magazine, Vol. 26: August, 1921 While the company does not attempt to fore cast 1921 results, it is understood that its cur rent production is running at the rate of from 400 to 500 ounces of platinum per week, and from 50 to 100 ounces of gold. The region under review is tropical and torrential rains occasionally cause heavy ﬂoods. After every ﬂood new values are found, show ing that enrichment is still in progress from the mother lode up in the mountains. But the greatest values lie against the bed rock from ten to 30 feet below the bottom of the rivers. Only modern dredges can reach this gravel, and the bed rock is soft enough to be cut - the buckets digging into it from six to eight inches, bringing up all possible values with a minimum of waste.
