The Kinsley mine may be<br \/>\nsomewhat unusual in its location in that it is at least 80 kilometers from the nearest<br \/>\nmodern gold mine and not apparently associated with any recognized regional gold-producing<br \/>\ntrend. Reconnaissance rock-chip and soil sampling of auriferous jasperoid<br \/>\noutcrops in the mid-1980s identified the gold anomaly in an area previously undisturbed<br \/>\nby mining or exploration activity. Several companies conducted exploration<br \/>\nprograms, which eventually culminated in Alta Gold Company putting the mine into<br \/>\nproduction in 1995. The mine produced approximately 150,000 ounces of gold<br \/>\nbetween 1995 and 1999. Average ore grades were commonly between 0.03 and 0.05<br \/>\nounce per ton.<br \/>\nThe dominant structure in the Kinsley mine is a wrench fault zone, approximately<br \/>\n750 meters wide, which strikes N60\u00b0W and is bounded on the north and south<br \/>\nby near-vertical left-lateral (?) strike-slip faults. Within the fault zone is a system of<br \/>\nanastamosing shears that bound rotated blocks of varying size composed of Cambrian<br \/>\nstrata. Gold production occurred from at least five distinct stratigraphically<br \/>\ncontrolled deposits in these rotated blocks. Anomalous gold does not occur in the fault<br \/>\nzones between the blocks. Selected members of at least six stratigraphic units of<br \/>\nMiddle Cambrian age host gold deposits. From youngest to oldest, these are the Notch<br \/>\nPeak Formation, Windfall Limestone, Dunderberg Shale, Big Horse Limestone, and<br \/>\nan unnamed sequence of limestone and siltstone. The most prolific gold producing<br \/>\nunit is the Dunderberg Shale, a sequence of thin-bedded calcareous siltstone, limestone<br \/>\nand shale.<\/p>\n","protected":false},"featured_media":4769,"comment_status":"closed","ping_status":"closed","template":"","meta":{"pmpro_default_level":""},"product_cat":[154],"product_tag":[],"_links":{"self":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product\/2385"}],"collection":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/comments?post=2385"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/media\/4769"}],"wp:attachment":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/media?parent=2385"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product_cat?post=2385"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product_tag?post=2385"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
