Rimrock Gold Corp. (the "Company"), is pleased to announce that it has completed an initial geological mapping and geochemical sampling program on the Rimrock gold-silver property in Elko County, Nevada.
The new geologic mapping has shown that the Rimrock gold property contains a large-scale, multiple-fault dilation zone gold-silver target situated just north of the Hollister Mine.
The principal epithermal Midas style gold-silver target was validated and even augmented by the new geologic mapping and sampling. Seventeen new samples were taken and analyzed, to further investigate alteration and mineralization seen on the property. These new detailed sample data show anomalous gold (to 13 ppb Au), silver (to 0.87 ppm Ag), antimony (to 5.5 ppm Sb), arsenic (to 39.5 ppm As), mercury (to 327 ppm Hg), selenium (to 6.5 ppm Se), and thallium (to 3.45 ppm Tl), which could be associated with Midas and Carlin-style gold-silver deposits along certain major fault structures on the property. These were surface spot rock chip samples taken well above the zone where anomalous gold values would be expected to occur. More detailed geochemical data from this program may be found in Rimrock Gold 's upcoming 10Q report.
The "Dilation" target was formulated based upon new geologic mapping and geochemical sampling by Rimrock's chief consulting geologist. The "Dilation" was formed when the northeast-trending IC Fault "jogged" to the east, forming a dilated rhomboidal shaped block in the jog area, which allowed hydrothermal fluids to more easily migrate upward and cause mercury-arsenic mineralization and alteration at the ground surface. Two small-scale mercury mines are situated in the southwestern part of this "Dilation" fault intersection block at Rimrock. The Dilation target at Rimrock shows highly altered, faulted, silicified felsic tuffaceous volcanic rocks at the surface, overlain by post-mineral rhyolitic flow domes similar to those near the Hollister Mine. The altered rocks locally show significant amounts of opaline silica and local mercury minerals, and local veining that crosscuts these rocks.
Newmont drilled several very shallow rotary drillholes in the project area in 1984 searching for near-surface disseminated gold mineralization. The "top elevations" of epithermal Midas-Hollister type gold-silver targets at Rimrock likely start at 150 to 300 metre depths below surface. The main zone of ore grade gold-silver mineralization at Midas is at least 500 metres in height, below the "top elevations". Local small poddy bodies of mineralization may occur above this "top elevation" level as at Midas. Rimrock Gold 's exploration efforts are focused upon discovery of deeper Midas and Hollister Mine style gold-silver mineralization, 125 to 300 metres below the surface. The elevations of ore zones at Hollister will be used to help guide exploration on the Rimrock property.
The Rimrock property is strategically located in a highly-mineralized epithermal gold-silver district, 16 Km southeast of Newmont's high-grade Midas Mine and 7 Km northwest of the Hollister Gold-silver mine of Rodeo Creek Gold. The Rimrock property also lies directly on the prolific Carlin Trend break that boasts numerous world-class sediment-hosted gold deposits. Excitingly, the Paleozoic rocks at Rimrock have been domally uplifted to be present at surface immediately west of the property boundary. Consequently, the rocks with Carlin-style gold potential could be much closer to the surface than at Hollister or at Midas. Anomalously elevated Carlin-only trace element thallium was found in three samples at Rimrock. This represents a geochemical leakage-upward anomaly of thallium and arsenic. The Company is now focused upon the discovery of relatively shallower Midas style gold-silver deposits.
"We are very excited to have completed the initial geological mapping and geochemical sampling work on the Rimrock property and discovering a significant new gold-silver target. Our plan is to analyze the data, initiate geophysical surveys, and commence a preliminary drill program this summer," stated President and CEO, Jordan Starkman .
Rimrock Gold is a diversified mineral exploration company focused on identifying, acquiring, advancing, and drilling high-grade Gold-Silver metal exploration projects in Nevada, and lithium exploration projects in Quebec. The company is managed by experienced and successful board members and advisors. The Company's main exploration assets comprise a 100% interest in the Rimrock, West Silver Cloud, and Pony Spur gold-silver properties in Nevada. In addition, the company owns the Abigail property in Quebec, comprising 177 map-designated cells totaling 9,400 hectares located in the James Bay, Quebec region of Canada, along with 12 map-designated cells just north of the Abigail property named Lac Kame and 25 map-designated cells named EM-1 totaling approximately 1,960 hectares.
