Jungo Mine
Jungo is located approximately 50 miles northwest of the town of Winnemucca, in northwestern Nevada.
The Jungo property lies between the historic Sleeper Mines and Allied Nevada Gold Corporation’s Hycroft Mine in Humboldt County, Nevada, and southwest of and across the valley from Newmont’s Sandman project. The Company has no direct association with any of these nearby mines.
The Hycroft Mine historically produced in excess of a million ounces of gold and recently announced that it plans to go back into production with the recent discovery of at least 5 million ounces of additional reserves.
The Sleeper Mine produced approximately 1.7 million ounces of gold, much of it from very high-grade near-surface veins. Recent exploration is finding new areas of strong ore-grade mineralization below the historic mine pit and along newly identified mineral structures outside the historic exploration area.
The Jungo property contains extensive exposures of brecciaed and silicified Paleozoic sedimentary rocks in contact with Tertiary volcanic rocks to the north and east. Surface samples from the property were anomalous in gold and silver, with several samples assaying better than 0.1 opt gold, and one sample greater than 0.6 opt. The apparent southwestern end of a siliceous gold system was exposed in the northern of two surface trenches completed by Dutch in March of 2007. Very limited exposures suggest that the possible hot springs silica associated with a minimally eroded volcanic vent extends for at least 2,000 feet northeastward under shallow alluvial cover.
Three additional trenches were dug in 2010. Trench JTP-3 was sited 1020 feet north of the 2007 trenches and was dug in an easterly down-slope orientation to cut across the lower margin of the eastern hillside of the Jackson Mountains. This new trench exposed altered Pretertiary meta-sedimentary and meta-igneous rocks that have been locally intruded by younger sialic shallow igneous rocks. All of the rocks have been fundamentally shattered and sheared.
Trench JTP-3 exposed the apparent continuation of the silicic gold-bearing volcanic vent that was seen in the northern 2007 trench. The JTP-3 trench interval from 140 feet to 270 feet contained the apparent vent zone, with erratic blocks of altered older metamorphic rocks mixed with and locally dominated by younger highly silicic gassy volcanics. The vent is gold bearing. The trench interval from 200 to 210 feet assayed 0.048 opt gold and 0.5-ounce silver. The interval from 240 to 250 feet contained 0.076 opt gold and 2.6 ounces silver. The adjacent interval from 250 to 260 feet assayed 0.017 opt gold and a half-ounce silver.
Trench JTP-2 was dug approximately 400 feet north of JTP-3. The eastern margin of trench JTP-2, the interval from 10 to 60 feet, averaged 0.028 opt gold and 0.67 opt silver. Within this zone, the 50 to 60 foot interval assayed 0.087 opt gold and .71 opt silver.
Trench JTP-1, located 400 feet to the north of JTP-2, contained measurable gold, up to 0.007 opt, with 0.7 opt silver, but appeared to be located west of the projected gold zone. Alluvial cover at the projection of the gold zone was too deep to trench.
All of the trenches contained evidence of abundant oxidized sulfides, shearing and silicification. Trench JTP-3, from 210 to 240 feet, contained locally visible copper oxides. The copper oxides are interpreted to be associated with an older period of mineralization, suggesting at least two distinct periods of mineralization.
The trenches appear to be near the southwestern end of a Tertiary volcanic mineralization event, although outcrop samples containing up to 0.1 opt gold were taken in strongly oxidized shattered metamorphic rocks several hundred feet to the south of the 2007 trenching, suggesting the mineralization may continue in both northeast and southwest directions.
Many of the 2007 and 2010 trench intervals were anomalous in gold and silver over a much broader width than the reported values. The geology suggests to Dutch Gold Resources that the property may have multiple gold zones downhill and to the northeast, that are hidden under colluvial cover. The geology of the trenches also suggests that the trenches exposed the lower temperature top of a gold system that could become substantially stronger deeper in the system.
