Scorpio Gold Corporation – Mining Gold in Nevada

Scorpio Gold Corporation


Scorpio Gold Corporation (TSXV:SGN) is a Canadian-based gold producer with assets located near Tonopah within the prolific Walker Lane gold belt in south-west Nevada. The company is the 70% owner and operator of the Mineral Ridge gold mine and 100% owner of the advanced exploration-stage Goldwedge property.

Currently in its third year of commercial production at Mineral Ridge, Scorpio Gold produced a total of 39,160 oz. of gold in 2013. The company is forecasting 40,000 to 45,000 oz. of gold to be produced at Mineral Ridge in 2014.

Scorpio Gold acquired the Goldwedge property and processing facility in December 2012. The company is assessing its exploration plans as well as the potential for toll milling at the Goldwedge mill, which is currently permitted for 400 tons per day.


  • Record production of 39,160 oz. gold in 2013; a 22% increase over 2012.
  • Cash cost per oz. gold sold reduced to US$734 in 2013; an 18% decrease from 2012.
  • 2014 production forecast: 40,000 – 45,000 oz. gold.
  • Poised for production growth through development of satellite deposits.
  • Exceptional safety record; honored by the Nevada Mining Association with a second place award in safety ratings in the small surface mining category.



Mineral Ridge

Mineral Ridge is a conventional open pit heap leaching operation located 6 km northwest of the town of Silver Peak and 56 km west of Tonopah in Esmeralda County, Nevada. The project area encompasses 5,010 hectares (12,380 acres) and is host to multiple deposits at exploration, development and production stages. Prior to Scorpio Gold and dating back to the late-nineteenth century, the property historically produced ~575,000 oz. of gold, including ~170,000 oz. from open pit and ~405,000 oz. from underground mining operations.

Scorpio Gold acquired a 70% interest in the Mineral Ridge project in March 2010 and under the terms of the joint venture agreement is currently entitled to receive 80% of the cash flow generated.

Following major site rehabilitation and refinement of the heap leaching and processing operations, Scorpio Gold achieved commercial production status on January 1, 2012.


In 2013, total gold production increased by 22% over 2012 to 39,160 ounces. Increased efficiencies, higher production levels and higher head grades led to an 18% reduction in total cash cost per ounce of gold sold from US$890 in 2012 to US$734 in 2013.


Quarterly Production by Metal & Cost

All gold is unhedged, and there are no underlying royalties in areas currently being mined.

In September 2013, the Mineral Ridge Mine Operation was recognized amongst some of the major producers in Nevada for its commitment to worker safety, when it received a safety award by the Nevada Mining Association for its performance in the 2012 calendar year.

2014 Production Guidance and Operations Forecast

Scorpio Gold has forecasted 40,000-45,000 oz. gold for its third year of commercial production at Mineral Ridge based on a conservative approach that estimates total cash cost for 2014 at US$800-$850 per ounce of gold sold. Budgets for capital expenditure, development, and exploration are set at US$1.2 million, $5.9 million and $3.9 million respectively for 2014.

Key parameters for the estimated 2014 production forecast include:

  • An average throughput of 2,840 short tons (2,580 metric tonnes) per day
  • An average grade of 0.061 oz. of gold per short ton (2.09 grams per tonne)
  • A waste to ore ratio of 4.3 to 1 for the Drinkwater and Mary/LC producing pits combined

Mineral Ridge Deposits

The Drinkwater and Mary are the two main deposits currently in production. Five additional satellite deposits known as Brodie, Bluelite, Solberry, Oromonte and Wedge are located west and southwest of Drinkwater Pit and lie in close proximity to the leach pad. Mineral reserve and resource estimates have been reported for the Drinkwater and Mary deposits and an Inferred mineral resource has been reported for the satellite deposits.

Near-term production growth opportunities lie in the Mary-Mary LC pit expansion and four of the adjacent satellite deposits currently in the development pipeline. A new reserve estimate extending Life of Mine is expected in Q2 2014.

Goldwedge Project

The Goldwedge project is located 54 km north-northeast of the town of Tonopah within the Manhattan Mining District of south-central Nevada. Scorpio Gold holds a 100% interest in the project, with the property covering three separate claim blocks and encompassing the Goldwedge, Keystone and Jumbo gold deposits.

The Goldwedge project includes a fully permitted underground mine with over 600 meters of development and a 400 ton per day mill facility with gravity circuit. Scorpio Gold has nearly completed rehabilitation of the plant and surrounding infrastructure.

The Goldwedge deposit is situated on the southern periphery of the Manhattan Caldera, approximately 16 kilometers south of the 15 million oz. Round Mountain Mine. Historic mining in the Manhattan Mining District dates back to the nineteenth century, with district-wide gold production estimated at 566,000 oz. The largest gold production came from the Manhattan Mine East & West pits located within a kilometer south of the Goldwedge deposit, where Echo Bay Mines reportedly produced an estimated 236,000 oz.

Scorpio Gold recently completed a preliminary 3-D geological model of the Goldwedge deposit based on data obtained from previous operators. Once interpretation and modelling of the mineralized system has been completed and a budget is in place, the company plans to proceed with surface and underground core drilling programs.

Also included in the Goldwedge property are the Jumbo and Keystone deposits, located 3.8 and 4.3 km southeast respectively from the Goldwedge deposit. Scorpio Gold considers both deposits to have considerable exploration merit given their style of mineralization, location along strike of the regionally significant northwest trending Reliance Fault Zone and both have been previously mined on a small scale via open pit method.


In less than two years, Scorpio Gold brought the idle Mineral Ridge gold mine into production and has since achieved marked success in increasing year-over-year gold production while decreasing its total cash cost per ounce of gold sold. Scorpio Gold produced a record 39,160 ounces at Mineral Ridge in 2013 and is currently forecasting 40,000 to 45,000 ounces of gold to be recovered in 2014. Near-term opportunity for production growth lies in the Mary-Mary LC pit expansion and adjacent satellite deposits currently in the development pipeline. A new reserve estimate extending Life of Mine is expected in Q2 2014.

Scorpio Gold also owns 100% of the fully permitted Goldwedge mine and mill facility in nearby Manhattan, Nevada, where surface and underground exploration is planned in 2014 that could lead to future production opportunities.
