Muscocho, the project operator, mined five bulk samples from five different areas of the mine. The test areas were chip sampled before and after blasting. All assaying and metallurgical testing was performed by Lakefield Laboratories.
Lakefield concludes that the average gold grade of the five samples after gravity separation and cyanide leach extraction, was 0.393 oz gold per ton — or 81% higher than the uncut chip sample average for the same five samples, which was 0.217 oz gold.
Based on the positive results, the partners feel that mill head grades may be higher than that predicted, once the Magnacon mine enters production.
Reserves as determined for surface drill data, are estimated at 1,440,580 tons grading 0.245 oz gold. Based on underground work, the portion of the reserves being readied for production — 445,000 tons — grade 0.361 oz gold. The bulk sampling program was designed to assess the reliability of these higher grading reserves, which were evaluated by chip sampling.
At the site, construction of the mill is nearing completion. Also, a new hydro line and substation are expected to be ready by late March. Muscocho has also completed more than double the amount of underground development than was originally planned, in order to ensure that the mine is ready for production. At full capacity, the Magnacon mine will be capable of producing more than 60,000 oz of old per year.
