Idaho Bureau of Mines Report ( highlights of 2 page synopsis) on War Eagle Mountain
- 3 primary gold and silver veins; “Oro Fino”, “Central” and “Poorman”.
- Oro Fino: over 12,000 ft., .5 to 25 ft. thick, grading .5 to 1.25 oz/ton….with 6 known associated veins.
- 40 other offshoots/veins associated with Oro Fino and Poorman veins.
- Another vein, Cumberland, produced very rich ore.
- Ore produced has averaged 2.52 oz./ton. (gold/silver combined).
- War Eagle production ratio was 1:14: 1 oz. gold to 14 oz. silver.
- Several large pockets of very rich ore, “hot spots”, are scattered throughout the mountain with grades of 25 oz. gold equivalent /ton….to 90-300 oz/ton.
- Estimates of reserves range from 500,000 to 3 million oz gold… confirmed by recent surveys …
- and with silver values added these reserves could reach 5 to 8 million ounces of gold equivalent. (rare precious metals analysis to be completed on assay samples re June 17th NR, ie; Rhodium in mineable concentrations).
- High grade veins are open at length and to depth in some areas.
- Considerable promise for future activity.
Idaho Geological (library) Report: highlights (thanks to ed86…2/27/09 posting on Stockhouse):
- prospecting laterally and at depth is justified.
- Average ratio form production reveal a 1:30 ratio of gold/silver. (differs with Idaho bureau Report of 1:14 ratio).
- Richest ore concentrations found where such veins as Oro Fin, Golden Chariot, Poorman and others were cross fractures intersected them…which require careful observation.
- Ore shoots (profitably extractable areas of veins) of up to 500 ft. horizontally, extend to the greatest depths mined (1500 ft.).
- Ore shoots are irregular and vary from lean to rich. It is possible that previous workings at depth was done in the most unpromising areas of the veins, without sufficient knowledge of such geological features as pitch.
- Previous operators “took out such ore as could be obtained wit a minimum of development work”. (remember that anything under 2 oz. gold was not considered economical at that time; up to 1933).
- “In fact, it is believed that never before or since has so little real exploratory work been done in so important a mining district”.
