LUPAKA ANNOUNCES PIT-CONSTRAINED RESOURCE ESTIMATE FOR THE CURCERO GOLD PROJECT
SRK Consulting (Canada) Inc. has prepared a conceptual Whittle pit in order to apply an economic constraint on the resource estimate for Lupaka Gold Corp.'s Crucero gold project. An amended and restated National Instrument 43-101-compliant technical report titled "Technical report for the Crucero property, Carabaya province, Peru" dated Oct. 22, 2013, which contains the pit-constrained resource estimate, has been filed on SEDAR.
Eric Edwards, Lupaka president and chief executive officer, commented, "The new pit-constrained resource for the Crucero gold project is a substantial improvement in confidence and quality, and contains approximately 90 per cent of the total unconstrained estimated gold mineralization." The resource estimate has been constrained by a conceptual pit shell in order to confirm reasonable prospects of economic extraction as set out in the CIM definition standards for mineral resources and mineral reserves and NI 43-101.
The Crucero gold project pit constrained resource estimate tonnage and grade is as displayed in the table.
Threshold Au Au cap (i) Au Au cap
(troy (troy
Category (g/t) Tonnes (g/t) (g/t) ounce) ounce)
Indicated 0.4 30,919,873 1.118 1.009 1,111,494 1,003,041
Inferred 0.4 31,201,648 1.143 1.025 1,146,219 1,027,806
(i) Gold grades capped at 17 grams per tonne
One troy ounce is equal to 31.10348 grams
The mineralization excluded as outside of the conceptual pit lies at depth and has an average gold grade of 0.71 g/t Au, much lower than the average grade of the tonnage within the constraining pit shell.
SRK Consulting (Canada) Inc. of Vancouver, B.C., aided with the economic constraint of the resource. The updated indicated and inferred mineral resource estimates reported herein are contained within a resource-limiting open-pit shell along 750 metres of strike and 360 metres in depth.
Parameters used to establish the conceptual pit are set out in the table.
Parameter Value Unit
Gold price 1,400.00 U.S.$/oz
Mining operating cost (mineralized
material and waste) 1.50 U.S.$/t milled
Process operating cost 13.00 U.S.$/t milled
General and administrative 2.00 U.S.$/t milled
Overall pit slope 47 Degrees
Gold process recovery 90 %
Mining dilution 5 %
The amended technical report also expands and clarifies other disclosure identified by the British Columbia Securities Commission technical disclosure review disclosed in the company's news release of Aug. 20, 2013. Readers are cautioned that the conceptual pit shell for resource model disclosed in the table does not constitute an economic analysis of mineral resources. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
