Exploration and gold deposit development company Glencar Mining has announced that the drilling programme carried out at its Komana West project, which forms part of the company’s Yanfolila project in southern Mali, is progressing well. A total of about 10 000 m of reverse circulation (RC) and diamond drilling has already been completed, and an additional 5 800 m of rotary air blast (RAB) drilling has been completed around the Komana West target.
Glencar Mining has two targets in Mali, the Yanfolila and the Sankarani projects. Glencar owns a 95% interest in the Yanfolila project, and is funding all exploration. In the Sankarani project, a subsidiary of gold mining giant Gold Fields is funding all exploration activities as part of a deal where the company can earn 65% interest in the licences, through expenditures of $12-million.
Glencar Mining CE Hugh McCullough says that the 250-km2 Komana West project was started in March 2005.
“This year, in the fifth phase of drilling, we plan to complete a total of about 17 500 m of RAB, RC and diamond drilling in, and around, the Komana West target. Glencar has already completed about 10 000 m of drilling at Komana West up to the start of the current programme, which means that the total at the end of phase 5, which is planned for May or June 2008, will be 27 500 m,” McCullough explains.
The RC and diamond drilling are designed to test the Komana West deposit at deeper levels and to explore areas marginal to the zone within which the recent preliminary independent resource estimate was calculated. Some infill drilling has also been carried out in parts of the resource model area where previous drilling density was inadequate.
McCullough says that the RAB drilling is testing outlying targets around the Komana West deposit and also on the adjoining Solona licence. Gold showings in the RAB drilling will then be followed up with RC drilling.
At this stage, McCullough says that target production cannot be established, as the company has yet to establish a mineral reserve on Komana West.
A diamond-core bore has also been carried out at the Komana East target, about 7 km east of the Komana West deposit.
The hole was drilled to obtain structural and geological data, which will assist in the design of the more extensive drilling programme planned for the Komana East target, during the first quarter of 2008.
Assay results are currently awaited for more than 4 000 samples, which have been submitted to the laboratory for assay. Glencar is hopeful that it will have sufficient assay results returned to enable it to make an interim announcement of the drilling results by the end of January 2008.
The company is also conducting airborne magnetic and radiometric surveys covering all five of the licences in both the Sankarani and Yanfolila projects in southern Mali. The area comprises a total project area of 1 250 km2. The aeromagnetic survey, with flight lines at 100 m and survey flying height at 60 m, will give additional detailed data on existing targets and will also help to define new, undrilled targets lying underneath laterite cover.
RAB drilling is also being carried out for geochemical purposes on the Bokoro licence in the Sankarani Project. The Bokoro licence forms part of the three-licence joint venture (JV) with the Gold Fields subsidiary.
“In each of the three licence areas making up the JV package, we drilled and received encouraging results. For instance, in Bokoro, the company achieved 21 m at 1,12 g/t; in Sanioumale 23 m at 1,45 g/t; and in Farasaba 43 m at 1,65 g/t,” McCullough says.
He says that results, thus far, have been encouraging for first-pass drilling programmes.
He comments that the company will establish a mineral reserve first, before settling on a production date.
Apart from the two targets in Mali, Glencar also has a 25-km2 licence near Tarkwa, in Ghana, which, McCullough says, the company has drilled with some very encouraging results, such as 3 m at 23,5 g/t and 12 m at 12 g/t. Glencar also has two gold licences in south-east Uganda, in the Lake Victoria Greenstone belt, but McCullough says that the company has not drilled there yet.
“Over the next five years, Glencar hopes to prove up a commercial resource ore reserve at Komana West, in Mali, and also to delineate at least two other targets with serious commercial potential in the Yanfolila and Sankarani projects. During that period, the company also hopes to advance the Komana West deposit towards commercial production, either independently, or in association with an industry partner,” McCullough concludes.
