Lupaka Gold Corp. Increases Resource Gold Ounces and Substantially Improves Grade at Crucero Gold Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 27, 2013) - Lupaka Gold Corp. ("Lupaka Gold" or "the Company") (TSX:LPK)(LMA:LPK) is pleased to report the Company's updated National Instrument 43-101 ("NI 43-101") compliant Indicated and Inferred mineral resource estimates for its 100% owned Crucero project located in southeastern Peru. The updated resource estimate has been prepared by Tetra Tech WEI Inc. ("Tetra Tech"), formerly Wardrop Engineering, of Vancouver, Canada (see Table 1 below).

The Company reports an indicated resource of 31.4 million tonnes at 1.01 gold grams per tonne (g/t) capped grade for 1,017,999 gold ounces at the A-1 Zone within the Crucero Gold project. In addition, the Company reports an inferred resource of 37.2 million tonnes at 1.00 g/t capped grade for 1,190,526 gold ounces at the A-1 Zone. Both the inferred and indicated categories now have a gold grade of 1 g/t or higher as a result of the 2012 drill results. As the Crucero mineralized zone continues to grow both in size and confidence levels, the Company has changed from the inverse distance squared method used previously, to the more conservative and appropriate ordinary kriging method for resource estimation. Using the more conservative methodology, estimated inferred gold ounces increased by 84% and inferred grade improved by 45% as compared to the last resource update completed March 5, 2012, primarily due to the inclusion of the 2012 drill results. The new estimation method did however result in estimated indicated ounces decreasing by 11% and indicated grade decreasing by 2%.

Eric Edwards, President and CEO of Lupaka Gold, commented, "We are extremely pleased with the growth in both gold ounces and grade of the A-1 Zone resource as announced in today's updated resource estimate. The A-1 resource is the cornerstone of what we believe is a district-style mining camp at Crucero. We are excited to continue testing additional anomalies at Crucero as we focus on increasing the total resource."

The following table summarizes resources estimated at a 0.4 g/t threshold (cut-off), effective as at February 27, 2013:

Tonnes Au
Au OZ*
Indicated 31,403,987 1.12 1.01 1,127,533 1,017,999
Inferred 37,170,436 1.15 1.00 1,370,729 1,190,526
* - Gold grades capped at 17 g/t 1 Troy Ounce = 31.10348 grams

Resource estimates generated at varying threshold (cut-off) gold grades are presented in Table 1 at the end of this news release.

Mr. Edwards continued, "The A-1 Zone is continuing to grow, and continuing to show that the resource has a distinct higher-grade core clearly visible in the cut-off grade sensitivity table. The A-1 Zone remains the only zone significantly drilled of the 11 known exploration anomalies currently identified at the Crucero Gold Project. This year, we plan to focus field work and drilling on new target anomalies that have not been drilled previously. With our current geological understanding of the A-1 Zone, we look forward to an exciting exploration year ahead."

This updated resource estimate includes the assay results from all 72 holes drilled (totalling 22,959 metres) within the A-1 Zone, including the 18 holes drilled in the A-1 Zone (7,579 metres) during the 2012 exploration program that was completed on December 31, 2012.

2013 Resource Estimate Methodology

The updated resource estimate in this news release has been prepared by Gregory Mosher of Tetra Tech. Mr. Mosher is a Qualified Person for the purposes of NI 43-101. The geological interpretation of the A-1 Zone has not been substantially modified from the model used in previous resource estimates: the zone has been modeled as a single geological solid that represents a grade shell that contains gold values generally greater than 0.1 g/t. This grade represents a natural and reasonably sharp boundary between unmineralized and continuously mineralized rock, although minor intervals with a grade of less than 0.1 g/t gold have been incorporated within the solid. These lower-grade intervals were not physically excluded from the geological solid by modification of the boundaries of the solid because it is improbable that they could be effectively segregated during mining and as well, the block model interpolation process accounts for these intervals and they can subsequently be identified and discounted on the basis of grade thresholds applied to the resource tabulation.

During 2012, Lupaka geologists carried out lithological logging of most of the holes that have been drilled in the A-1 Zone. This work enhanced the previous understanding of the geological control of the distribution of gold within the Zone but has not resulted in a modification of the geological model used for resource estimation because gold distribution is not sufficiently constrained by lithology to permit the adoption of a lithological model without significant sacrifice of resource of potential economic significance.

On the basis of the operating costs and cut-off grades used in a number of open pit gold mines in Peru and elsewhere, a lower grade threshold of 0.4 g/t gold is considered reasonable for this type of deposit in this type of location. The resource at this lower limit is considered as the base case and is highlighted in Table 1. Using ordinary kriging and at a lower threshold of 0.4 g/t, the A1 Zone is estimated to contain an Indicated resource of about 31.4 million tonnes with an average, capped grade of 1.01 g/t gold (approximately 1.02 million Troy ounces) and an Inferred resource of about 37.2 million tonnes with an average, capped grade of 1.00 g/t gold (approximately 1.2 million Troy ounces). For the current estimate, the capping level was re-assessed to take into account the additional data acquired, and a capping level of 17 g/t gold continues to be appropriate. Bulk density measurements of three core samples from drill hole CR-01 were made by SGS Analytical Laboratories in Lima. The average bulk density of these three measurements (2.86, 2.82, and 2.93) is 2.87.
