  • (Local) Host rocks have been silicified, jasperized, argillized, and decarbonatized. Of these, silicification is the most common alteration within the orebody. Chainman Shale and Pilot Shale are argillized and silicified.

Comments on other economic factors

  • There has been no known production reported for the Pan deposit. Reserves in 1989 were reported as 241,000 ounces of gold. In 1998, drill-indicated and inferred reserves were 10.86 million tons of ore grading 0.022 opt Au. A study by Mine Development Associates in 2003 increased previous estimates to include 17.9 million tons of material grading 0.019 oz gold per ton in the indicated category with 8 million tons grading 0.016 oz gold in the inferred category, for a total resource of 47,000 ounces of gold.

Comments on development

  • In 1978, Lyle Campbell, a Nevada prospector, staked the property under a joint venture arrangement with Amselco, a subsidiary of British Petroleum. Over the next eight years, the partners drilled 85 reverse circulation drill holes outlining a low-grade resource at what is now known as the North Pan zone. Hecla Mining explored the property briefly in 1986, but most of the exploratory drilling occurred between 1987 and 1992 under a joint venture between Echo Bay Mines, now part of Kinross Gold, and Alta Gold. During this time over 250 drill holes were completed in the North Pan area and the South Pan zone was discovered. By 1998, the property was under the control of Latitude Minerals. The junior completed a resource study, which outlined two potentially mineable resources totaling 254,000 oz of gold and drilled over 60 holes in the North and South Pan areas, as well as drill testing several new target areas dubbed Syncline, Red Hill and Horseshoe. In 2002 Latitude relinquished the property and in 2003, Castleworth picked it up from Latitude in a deal to acquire 11 properties in Nevada, including the Pan project. In mid-2006, Pan-Nevada Gold Corp. announced that recent drill results at the Pan Project include 0-20 feet @ 0.010 opt Au (236); 0-55 feet @ 0.026 opt Au (237); 0-35 feet @ 0.011 opt Au (238) and 0-55 feet @ 0.039 opt Au (240).

General comments

Subject category Comment text
Deposit Mineralization occurs in sediments primarily in the basal portions of the Pilot Shale. At the North Pan orebody, mineralization is hosted within silicified Pilot Shale and jasperoid. At South Pan, mineralization is hosted within argillized limestone and shale. The Pan deposits identified to date are sediment hosted, epithermal deposits located primarily in the basal portions of the Pilot Shale. The Pan claim group covers a large alteration system, nearly four miles in length, centered on a regional-scale fold axis mineralized along its full length. The axis of this fold coincides with a N-S regional fault structure, which appears to be one of the conduits for the mineralizing fluids. The entire feature is also coincident with the Battle Mountain-Cortez Trend, which intersects the regional N-S structure from the N-W to S-E direction. As a result of the multiple series of faulting and good thicknesses of favorable host rocks (primarily Pilot Shale), Pan presents excellent potential for several additional discoveries of mineralization.
