Dry Placers in Southern Baja
June 2003 by Edgar B. Heylmun, PhDThe southern tip of Baja California is dominated by the Sierra de la Laguna, a 70-mile-long mountain range that reaches elevations of 7,095 feet. The range is also known as the Sierra de la Victoria.
Bolivia’s plan to nationalize its natural gas industry and exert greater state control over all of its natural resources has North American mining companies fretting over their future prospects extracting the nation’s rich resources of gold, silver and tin.
Rich placer gold deposits were found in the Klondike district of Yukon in 1896, and a wild gold rush ensued. The district is east and southeast of Dawson (pop. 1,300), mostly along Bonanza and Hunker Creeks, and their tributaries.
Down around 10 or 12 inches I hit a large cobble that appeared to be one type of hot rock for this area. I thought bad things about the new technology until I checked the rock.
I love to see old-timer workings while I am out detecting for gold. For one thing, it assures me that gold came from there. Second, it tells me gold should almost certainly still be there.
While most small-scale prospectors and miners focus their energies on placer deposits, most large mining companies put their efforts primarily into hard rock mining. Although many miners may see these as two separate worlds that can never meet, a better understanding of hard rock mining for small operators can be very helpful in many ways.
...if you are out prospecting and find something that looks very much like a nugget but has an odd greenish-gray cast to it, don’t be too quick to simply toss it aside as junk.
I’ve been fascinated by iron minerals for many years. So let’s take a look at this very interesting and colorful element.
