The Fox Spring Project
History
The Fox Spring Project of Grizzly Gold Corporation, located in Humboldt County, Nevada, is in the southern Jackson Mountains, and is approximately 150 miles northeast of Reno and 55 miles west of Winnemucca, Nevada. Geologically, the property and area is primarily covered by Quaternary alluvium. Where outcrop is exposed, much is sub-crop of weathered and decomposed Triassic/Permian intercalated and interbeded sediments of argillite, siltstone and limestone with zones of silicified/jasperoidal outcrops forming hill tops in the eastern and southern portions of the property.
In 1985, the WX Syndicate staked claims that encompass the area of the current LB portion of the property. Initial activity included soil and rock chip sampling, geologic mapping, and shallow trenching. WX’s trenching revealed clay alteration and favorable limey shale units with some gold values with consistent anomalous gold throughout the length of four trenches. A two-phase drilling program followed trenching. The two-phase program utilized conventional rotary and air track drilling methods.
Seven shallow open-hole rotary holes were completed for 1,080 feet in 1987. The holes targeted gold anomalous zones within fractured and limonite stained Triassic shale and phyllite. Anomalous near-surface gold values were intercepted in four of seven holes. An additional 26 shallow air track holes were completed in a rough grid pattern filling in between the two areas of trenching. In this instance, air track holes were utilized for geochemical sampling of the near surface gold values and were used as a targeting tool for deeper drill tests in the future. Drill logs and assays are available from all sampling and drilling completed by WX Syndicate.
In 1988, U. S. Borax staked ground that is now covered by the Vixen claims. Borax reportedly completed soil and rock chip sampling, geological mapping, and drilled five reverse circulation drill holes for 1,190 feet. The holes reportedly targeted a northwesterly structural zone within similar stratigraphy to that of the LB portion of the claims.
In 1992, Independence Mining Company controlled the LB Vixen ground as part of a larger exploration project in the Jackson Mountains comprising over 1,600 claims. Independence did not conduct work on the LB Vixen property.
In February 2006, Nevada Mine Properties II, Inc. staked 20 unpatented lode claims covering the former WX Syndicate drill area and extensions.
Recent Exploration
In January 2012, the results of a geochemical rock chip sampling were compiled and posted on a topographical base map. Three areas were recognized for an initial phase of soil sampling to identify potential drill targets.
In March 2012, Phase 1 of soil sampling was completed. The scope of Phase 1 covered approximately 580 acres on the property with a total of 205 soil samples collected. Results from Phase 1 displayed at least three anomalies and added 21 new claims that were staked and filed east and south of the original 61-claim block, bringing the total number of claims on the LB Vixen to 82.
Additionally, four rock outcrop samples were taken during a field trip to the LB Vixen to confirm the results on Phase 1 of soil sampling and conduct prospecting in anomalous areas. The results of the four rock outcrop samples displayed anomalous gold and silver as well as elevated pathfinder elements.
Phase 2 of soil sampling commenced in May of 2012. An additional 166 soil samples were collected for gold pathfinder element analysis.
A total of 50 rock chip samples have been taken on the LB Vixen property. The samples were scattered throughout the property where outcrop could be found. Three areas of mineralization were recognized as a result of the rock chip sampling. These three areas all exhibited characteristics of iron flooding and silicification forming jasperiodal outcrops in the Triasic/Permian sediments.
Assay results from the four Phase 1 drill holes on the LB Vixen property are extremely encouraging. All four widely spaced holes encountered gold mineralization demonstrating the possible existence of a large bulk tonnage, sediment hosted gold deposit on the LB Vixen property. Further study of the results will help determine the next phase of testing and target selection for Phase 2 drilling in 2013.
Four reverse circulation angle holes totaling 2500 feet were widely spaced along a zone of anomalous gold mineralization intermittently exposed over a length of roughly 9000 feet and width of nearly 2000 feet. Due to the general lack of outcrop exposure, the first phase of drilling was intended to help determine the overall extent and trend of mineralization. Mineralization was encountered in all 4 holes.
Future Plans
Further drilling, exploration and claim staking will be ongoing with encouraging results from Phase 1 Drilling.
