The test work shows that the A-1 Zone gold extraction is independent of sodium cyanide concentration in the range 500 to 1500 mg/L. Opportunity remains to further reduce the cyanide dosing and concentration regime and thereby reduce operating costs. Pre aeration with air was found to provide sodium cyanide consumption reduction and further work in this area is warranted. Sodium cyanide consumption of nominally 2 kg/t was determined when sodium cyanide concentration of 500 mg/L was tested.
Conclusions and Recommendations from the test work
The test work completed to date has suggested metallurgical performance is likely associated with arsenic and pyrrhotite minerals, and potentially antimonial minerals, and is a function of grind size and mineral liberation. As the deportment and location of these minerals is not defined, there is a need to understand this aspect and also the associated metallurgical behaviour by variability testing.
Additional variability test work is required to define comminution and metallurgical parameters with ore types and mineralisation in the resource in addition to providing engineering data such as settling characteristics, viscosity, materials handling and rheology. Use of oxygen for pre aeration, review of lead nitrate addition, application of reduced cyanide concentration and gold deportment evaluations all provide opportunity to improve extraction efficiency and project economics.
About the Company
Lupaka Gold is a well-financed, Peru-focused gold explorer with geographic diversification and balance through its asset-based resource projects spread across northern, central and southern Peru.
Lupaka Gold's flagship project is the Crucero Gold Project, its 5,500 hectare gold property is located in the northern part of Puno, a southern region of Peru. The Company holds a 100% interest through Minera Pacacorral S.A.C. in the Crucero Gold Project, containing an indicated resource of 1,017,999 gold ounces at 1.01 g/t and an inferred resource of 1,190,526 gold ounces at 1.00 g/t. Since commencing active exploration in April 2010, the Company has reported annual NI 43-101 compliant gold resource estimate increases for the Crucero Gold Project from 2011 to 2013 (see the Company's most recent technical report on www.sedar.com).
As a result of the Company's recent acquisition of Andean American, Lupaka Gold's assets also include the 100% owned Invicta Gold Project in the central Lima region of Peru, which has near-term underground gold, silver and copper development potential. Lupaka Gold also owns a 17% stake in Southern Legacy Minerals Inc., owner of the AntaKori copper-gold deposit located in the northern Cajamarca region of Peru.

The forward-looking information contained in this news release is made as of the date of this news release. Except as required under applicable securities legislation, the Company does not intend, and does not assume any obligation, to update this forward-looking information. Forward-looking information includes, but is not limited to, statements with respect to mineral resource estimates, future upgrading of mineral resources, that the structural geological interpretation report will help create future exploration targets, and related outcomes. Often, but not always, forward-looking information can be identified by the use of words such as "plans", "expects, "is expected", "budget", "scheduled", "estimates", forecasts", "intends", "anticipates", or "believes", or the negatives thereof or variations of such words and phrases or statements that certain actions, events or results "may", "could", "would", "might", or "will" be taken, occur or be achieved.
The forward-looking information contained in this news release is based on certain assumptions that the Company believes are reasonable, including, with respect to mineral resource estimates, the key assumptions and parameters on which such estimates are based, that the current price of and demand for gold will be sustained or will improve, that general business and economic conditions will not change in a material adverse manner, that financing will be available if and when needed on reasonable terms, that supplies, equipment, personnel, permits and local community approvals required to conduct the Company's planned exploration and development activities will be available on reasonable terms, that results of exploration activities will be consistent with management's expectations and that the Company will not experience any material accident, labour dispute, or failure of equipment.
However, forward-looking information involves known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking information. Such factors include, among others, risk that actual results of exploration activities will be different than anticipated, that cost of labour, equipment or materials will increase more than expected, that the future price of gold will decline, that the Canadian dollar will strengthen against the U.S. dollar, that mineral resources are not as estimated, unexpected variations in mineral resources, grade or recovery rates, risk of accidents, labour disputes and other risks generally associated with mineral exploration and unanticipated delays in obtaining or failure to obtain community, governmental or regulatory approvals or financing. Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking information, there may be other factors that cause actions, events or results to not be as anticipated, estimated or intended. There can be no assurance that forward-looking information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Readers are cautioned not to place undue reliance on forward-looking information due to the inherent uncertainty thereof.
