Capstone Mining Corp. is a Canadian base metals mining company with two producing copper mines, the Cozamin copper-silver-zinc-lead mine located in Zacatecas State, Mexico and the Minto copper-gold-silver mine in Yukon, Canada. In addition, Capstone has two development projects, the large scale 70% owned Santo Domingo copper-iron-gold project in Chile in partnership with Korea Resources Corporation and the 100% owned Kutcho copper-zinc-gold-silver project in British Columbia, as well as exploration at properties in Australia, Canada, Chile and Mexico. Using its cash flow and strong balance sheet as a springboard, Capstone aims to grow organically through continued mineral resource and reserve expansions and through acquisitions in politically stable, mining-friendly regions.

The mineral resource estimate reported herein for the Fireweed and Inferno North Deposits were estimated
, P.Geo. of Kirkham Geosystems Ltd. Mr. Kirkham is the Independent Qualified Person under NI 43-101 responsible for the mineral resource estimate and has reviewed the information in this release in respect of the mineral resource estimate. The database used to estimate the Fireweed and Inferno North deposits was inspected and verified by the author. The author is of the opinion that the current drilling information is sufficiently reliable to support estimating mineral resources. The mineral resources presented herein have been estimated in conformity with generally accepted CIM "Estimation of Mineral Resource and Mineral Reserves Best Practices" guidelines and are reported in accordance with Canadian Securities Administrators' National Instrument 43-101. Mineral resources are not mineral reserves and do not have demonstrated economic viability. In the opinion of Kirkham Geosystems Ltd., the block model resource estimate and resource classification reported herein are a reasonable representation of the mineral resources at the Fireweed and Inferno North deposits at the current level of sampling.
With respect to the mineral resource estimates, the analytical method for the copper and silver analyses is aqua regia digestion of the samples followed by atomic absorption spectroscopy. Gold is analysed by fire assay fusion with atomic absorption spectroscopy finish. Analyses are carried out by ALS Chemex in
. When visible gold is noted in drill core samples or regular fire assay values appear abnormally high, screen metallic assay method is used to determine the total gold content and gold content of different size fractions. This is considered industry best practice when dealing with coarse gold mineralization where a nugget effect is suspected. This determination is accepted as the most representative value and is used in the assay database for resource calculations. Blank and standard samples are used for quality assurance and quality control. Where more than two check samples assay outside expected ranges, the entire batch is re-assayed. After the completion of planned drill programs, random check assays will be carried out by Inspectorate-IPL of
