Mine History

Located in the state of Sonora, in northern Mexico, Lluvia de Oro was designed as a large tonnage, low-grade gold operation. The property currently includes one open pit, two heap leach pads and a gold recovery plant. Under Great Lakes Minerals Inc. the facility entered into production in May 1996, and was later operated by Santa Cruz Gold Inc. ("Santa Cruz") and finally by Compania Minera Lluvia de Oro S.A. de C.V.

The mine had an anticipated average production rate of 25,000 ounces per year from an initial reserve of 4.6 million tonnes grading 0.82g Au/t or 121,000 ounces. Santa Cruz had projected that the life-of-mine cash costs for the Lluvia de Oro Gold Mine would be in the range of US$235 per ounce.

Mining & Exploration

During 1997, 1.65 million tonnes of ore, with an average grade of 0.75g Au/t were mined and placed on the pad at an average cash cost of US$3.76 per tonne. As a result of El Nino, the project area received twice the average annual rainfall. Production for 1997 was 20,688 ounces versus the projected 25,000 ounces. Cash costs averaged US$299 per ounce, which was US$79 higher than the projected US$220 per ounce. The cash cost overrun was not only due to the shortfall in production but also due to increased mining (an extra 320,000 tonnes of ore were placed on the heap in an attempt to offset the negative impact of the excess rains).

Santa Cruz completed a drilling program in the 2nd quarter 1997 successfully expanding the existing proven reserves(a) by more than 60%. This 6,100 metre drill program was successful in adding 2.1 million tonnes grading 0.81g Au/t or 54,400 oz. Additional lower grading material, which may be mined and leached later in the mine life, added another 9,500 oz for a total of 64,000 oz. These reserves were defined along 300 metres of strike from the limit of the current open-pit.

The new reserves(a) increased the proven reserves(a) to 4.7million tonnes grading 0.81g Au/t, representing an increase of 64%. In addition to adding mine life to the operation, the reserves discovered in 1997 allowed for an increase in production scheduled for 1998 to approximately 28,000 ounces.

Drilling delineated an additional higher-grade resource(a) of approximately 4.5 million tonnes grading 0.95g Au/t along the same structure. Highlights from the drill program include three holes, all of which ended in "ore" and appear to have intersected a deeper, higher grading zone. These holes include:



hole L188, located approximately 60 metres on strike from the pit
limits, which intersected 15.2 metres grading 2.3g Au/t;

hole L194, on the next section, intersected 19.8 metres grading
1.8g Au/t; and

hole L202, approximately 200 metres from the current pit along
strike, intersected 7.6 metres grading 3.8g Au/t.


A deeper drilling program comprised of six holes was completed in the 3rd quarter 1997. Four of the six holes intersected good values including hole L239 which intersected 30 metres grading 1.5g Au/t, hole L240 which intersected 14 metres grading 1.62g Au/t, hole L241 which intersected 39 metres grading 2.29g Au/t and hole L242 which intersected 18 metres grading 1.33g Au/t.

The Company is currently in the process of conducting due diligence on the Lluvia de Oro gold mine and our engineering team is reviewing options for re-initiating mining, production, rinsing the leach pad and heap leach processing. Columbia will now commence a National Instrument 43-101 qualifying report on the Lluvia Property.

(a)The terms reserve and resource are as reported by Santa Cruz and do not necessarily conform to NI 43-101 standards.

Cautionary Note: The tonnages, grades, assays, drill intercepts, production figures and other technical data are taken from historical records prior to the implementation of NI 43-101. While the data is believed to have been acquired, processed and disclosed by persons believed to be technically competent it is unverifiable at present. The data source for the Lluvia de Oro is largely the 1997 Annual Report of Santa Cruz Gold Inc.

A qualified person as defined under NI 43-101 has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves. Columbia is not treating the historical estimates as current mineral resources or mineral reserves as defined in NI 43-101 and the historical estimate should not be relied upon.
