Patriot Gold Announces Results Of Preliminary Economic Assessment For Moss Mine Project Results Support Strong Potential Economics Including PHASE II Pre-Tax Internal Rate of Return of 117.9%

LAS VEGAS, April 10, 2013 /PRNewswire/ -- Patriot Gold Corp. (OTC: PGOL) or ("Patriot Gold" or the "Company"), a developing gold and silver production and exploration company, today announced the results of a Preliminary Economic Assessment ("PEA") for the Moss Mine Project, located in the historic and active Oatman mining district near Bullhead City, Arizona.

Based on the recently announced updated resource estimate and an independent technical report co-authored by CDM Smith, Inc. ("CDM") and Metal Mining Consultants Inc. ("MMC") dated March 13, 2013 (the "Technical Report"), the PEA provides an evaluation of the economics of open pit mining and heap leach processing in Phase I and Phase II production for the Moss Mine Project.

Phase II Preliminary Economic Assessment Highlights*:

  • Mine life of five years, 5,000 tpd, 42,000 AuEq oz/yr
  • Pre-tax IRR of 117.9%
  • Pre-tax payback of 15 months
  • Pre-tax NPV @5% $110 million
  • Capital expenditures $26.6 million
  • Capital/average annual AuEq oz production $633/oz
  • Cash Costs/AuEq oz $490/oz
  • Metallurgical recoveries of 75-85% for gold and 55-77% for silver

*All figures are in USD unless otherwise stated, are based on a gold price of $1,500/oz and predictions that 100% of the Phase I and II mineral resource will be minable.

"We are pleased with the outcome of the Preliminary Economic Assessment which not only supports the strong economic potential of the Moss Mine Project, but also provides sound guidance to the next phases of operations," said Bob Coale, CEO of Patriot Gold. "We believe that there continues to be upside in maximizing results from the in-field operations during the Pilot Plant operations phase (Phase I), from possible pit expansions as a result of the mine exploration programs and of course, possible Mine Life Extension or Expansion (Phase III). With the PEA results guiding our way, we remain very optimistic on the Moss Mine Project outlook and look forward to keeping our shareholders informed on our progress throughout the next critical phases of operations."

The Three-Phase Mine Development Plan, as outlined in previous news releases, is designed to move the Moss Mine Project forward in a defined and thoughtful manner - from conceptual design and laboratory test work to on-site pilot plant testing (Pilot Plant - Phase I) and then onto operations (Phase II). Phase II is independent from Pilot Plant - Phase I, and will only proceed if Phase I is successful. Phase III is conceptual only, will depend on the success of Phase II, and so is not included in the PEA. Phase III would involve mine life extension and/or expansion of production volumes.

A summary of the key parameters and results of the PEA follow.

*Gold equivalency is based on a silver:gold ratio of 50:1 and assumes 100% recovery of all metals.

*Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources estimated will be converted into Mineral Reserves estimates.

*Mineral resource tonnage and contained metal have been rounded to reflect the accuracy of the estimate and numbers may not add due to rounding.

*Resources were based on 36,805 meters of drilling in 658 exploration drill holes and 530 meters of channel sampling. There were a total of 7,677- five meter composite samples used in the estimation of gold and silver. MMC used Inverse Power Distance (ID3) as the preferred estimation technique for the Moss Mine Project.

*MMC capped gold assays, prior to compositing 5 meter samples, at 17 grams per tonne and silver at 140 grams per tonne in order to limit the effect of high grade outlier grades in the estimation of mineral resources.

*MMC applied Industry Standards in the selection of the drill hole and assay information gathered from historic and current exploration programs in its determination of Measured Mineral Resources, Indicated Resources and Inferred Resources.

Resource Estimates for Phase III - Mine Life Expansion / Extension:

The anticipated operating period for Phase I is 15 months and for Phase II is five years, including development and construction. As previously stated, Phase II will only proceed upon the successful completion of Phase I.

Pilot Plant - Phase I and operations - Phase II measured and indicated resources encompass 265,000 of the total 654,000 ounces gold equivalent of global resources estimated by MMC. Upon the completion of Phase II, 389,000 oz AuEq will remain. Extending mining and processing operations onto unpatented land by mining along strike and to depth has the potential to significantly extend the life of the mine. This will be the subject of further investigation concurrent with Phase II operations. This investigation will incorporate permitting, technical, economic, and financial elements into one or more pre-feasibility and/or feasibility studies.

It should be noted that the Phase I and Phase II resources described are physically constrained to that which can be reasonably extracted by limiting mining and related facilities to patented - or private - land. The conceptual Phase III mine plan would be pursued without the physical constraints of limiting operations to patented land and will require normal course approvals from various US governmental departments and mining authorities.

Based on development of the initial resource solids containing the Phase I and Phase II resources, the mining extraction recovery rate of the in-situ resource is anticipated to be 100 percent.

Metallurgy:

Overall metallurgical data shows that ore from the Moss Mine Gold-Silver Project is readily amenable to agglomeration/heap leach cyanidation processing. Column test recoveries obtained from the bulk samples, finely crushed using rolls crushers and agglomerated using cement as a binder, ranged from 75% to 84.6% for gold and from 61.3% to 76.6% for silver. Recovery percentages are summarized in the table below:

Gold extraction was still in progress when column leach tests were terminated for purposes of completing the PEA and is expected to increase further with a longer leach cycle. Preliminary data from an ongoing column leach test indicate that the low grade mineralization will be amenable to agglomeration/heap leach cyanidation processing after roll crushing to a 95%-1/4" feed size. Use of industrial scale high pressure grinding rolls (HPGR) has the potential to improve liberation and yield higher recoveries.

The favorable results from the labatory metallurgical testing provide the basis for proceeding with the proposed field testing Pilot Plant - Phase I. Metallurgical data from the Pilot Plant program will be collected and analyzed for use in the design of operations - Phase II. Both higher grade and lower grade mineralized rock is expected to be tested in the Pilot Plant. Although positive results have been obtained to date, additional metallurgical test work will be required. Consequently, recoveries used in the PEA have been conservatively scaled back to 75% for Au and to 55% for Ag.

Exploration:

The Preliminary Economic Assessment recommends a continued exploration program to further delineate the mineralization at the Moss Gold-Silver Project. The limits of mineralization are still open at depth and to the west. The recommended drilling program includes additional drilling of 2,200 meters and associated costs are outlined in the table below:
