Global Minerals Releases Positive Preliminary Economic Assessment of Its Strieborna Silver-Copper Project

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Dec 12, 2014) - Global Minerals Ltd. (TSX VENTURE:CTG)(DFPM.F) ("Global" or the "Company") is pleased to announce the results of a positive Preliminary Economic Assessment ("PEA") for its 100%-owned Strieborná silver-copper-antimony deposit in Slovakia ("Strieborná" or the "Project").

The PEA envisions an underground mine and conventional flotation milling operation with an initial seven year mine life. Mining output is modeled at 300 tonnes per day ("tpd") for the first two years, increasing to 500 tpd starting from year three. Over the life of mine ("LOM"), the Project is estimated to produce an annual average of 1.4 million silver ounces and 4.1 million pounds of copper. Cash cost per ounce of silver, after copper by-product credits, is $10.82 per ounce.

PEA Highlights (all amounts in US dollars unless otherwise indicated)

  • Base Case is stated assuming $20/oz silver and $3.00/lb copper as long term metal prices.

  • Pre-tax NPV (5%) of $11 million, IRR of 12.4%, and payback of 4.7 years.

  • Post-tax NPV (5%) of $5 million, IRR of 8.3% and payback of 5.1 years.

  • Pre-development capital costs of approximately $25.3 million, including contingency.

  • Average silver cash costs (net of by-product sales) of $10.82/oz silver (see Non-U.S. GAAP Performance Measurement below).

  • Post-tax LOM free cashflow generated is approximately $14.9 million.

  • Average annual production in the initial 5 years is 1.4 million ounces of silver and 4.3 million pounds of copper.

  • The study contemplates mining 983,000 tonnes of mineral at average grades of 307 gpt Ag and 1.3% Cu.

  • LOM production of 9.5 million silver ounces and 28 million pounds of copper.

  • LOM average silver and copper recovery in concentrate of 98%.

  • Silver-copper concentrate with average grades of 6,570 gpt silver and 27.8% copper

The following table summarizes the main economic outputs of the discounted cash flow.
