Timberline Gold is a mineral exploration and resource development company focused on gold and copper discoveries in north-central Nevada. Timberline’s projects are focused within the world-class mining jurisdiction in the famous Battle Mountain-Eureka Trend. The company’s flagship project is the Lookout Mountain Project which contains a high-grade gold zone as part of a >500 K oz (M&I) resource which is open for expansion.
Location of the Eureka Property South of Eureka, NV, and the
Ruby Hill/Archimedes Mine
Timberline is working on the Eureka project, a gold project located on the south end of Nevada’s Battle Mountain – Eureka Trend, and immediately south of the two-million ounce Archimedes / Ruby Hill mine complex. The project includes Timberline’s Lookout Mountain resource area along with a pipeline of earlier-stage targets that feature past gold production, historic gold estimates, and/or drill-indicated gold mineralization. Timberline acquired the Eureka property, including Lookout Mountain, in its 2010 acquisition of Staccato Gold.
Gold mineralization at Eureka is of the Carlin-type, a class of gold deposits first identified and best known from Nevada where they may contain multi-million oz resources and/or reserves. Timberline’s discovery to-date at Lookout Mountain includes an NI43-101 resource at Lookout Mountain and an associated high-grade zone, and several sites of drill indicated gold mineralization.
Replacement deposits of lead-silver-zinc-gold mineralization were discovered in the Eureka district in 1864 with substantial production primarily from 1870 to 1890. Gold mineralization that contained no base metals was discovered in 1904 at Windfall Canyon, about 3.5 miles northeast of Lookout Mountain. The Windfall-type mineralization differed from other mineralized bodies in the Eureka district in that it consisted of low-grade gold shoots with indistinct assay walls. After discovery of disseminated gold deposits in Nevada’s Cortez district during the 1960s, Windfall received renewed exploration interest in the gold-only mineralization, resulting in mining beginning in the early 1970’s with ultimate production of approximately 130,000 oz of gold from three aligned open pits. Follow-up exploration in the district into the 1980’s led to production of approximately 18,000 ounces from the Lookout Mountain open pit by Norse Windfall Mines, Inc, a consortium of Norwegian, Swiss and American Companies.
[FYI, Lookout Mountain was initially mined by the Norse Windfall Mines Group (with management consulting assistance provided by Campbell, Foss & Buchanan, Inc. (C,F&B) based in Houston, Texas) for the near-surface gold oxide ore in the 1980s. The group constructed a substantial haul road costing approx. $800,000. (1980s $) to transport the ore to the heap-leach pads and electrolytic processing mill located in New York Canyon to the north, which produced very high-quality gold dore (with a gold price at ~$300.00/oz). NMWI encountered the deep sulfide gold mineralization below the gold oxide ore but did not develop the resources because the project would require substantial funding for roasting the sulfide ore, etc. The project was offered to Battle Mountain Gold at the time.
