|Location and accuracy||This prospect of uncertain boundaries consists of 521 claims covering about 16,000 acres near Tarnis Mesa, an informal name that probably refers to the hills that occupy most of section 10, T.31 S., R. 41 E. The coordinates are arbitrarily on the top of hill 535, which presumably is the top of the mesa.|
Geologic descriptionIn 2009, Geohedral LLC with financial backing from the Beard Company staked 521 claims totaling about 16,000 acres in the Tarnis Mesa area (which probably refers to the unnamed low hills in section 10 that rise above the coastal plain) (Beard Company, 2009 [Annual Report]). These claims were contiguous to the claims they had staked the previous year along the coast (YA013). The Tarnis Mesa claims were believe to have significant quantities of iron, titanium, gold, silver, platinum, and palladium in black sands in elevated marine beach terraces. In 2009, Geohedral drilled 30 holes up to 27.1 feet deep and another 30 holes 3 to 6 feet deep (Beard Company, 2009 [gold discovery]). As reported in a press release: 'Preliminary evaluation of the assays indicates that the unconsolidated materials above the bedrock in the Tanis Mesa area contain appreciable amounts of gold and silver, averaging 0.30 oz/ton of gold and 0.75 oz/ton of silver. The 400 claims of primary interest are projected to produce 34,800,000 troy ounces of gold' In 2010, the Beard Company commissioned an independent analysis of the samples and reported that 'Geohedral's mining claims failed to indicate commercial quantities of gold or silver in any of Geohedral's present claims and have shown significantly less magnetite and ilmenite within the Black Sands area than was documented previously.' (Beard Company, 2010).
