Galane Gold, listed on the TSX-V, has announced that prospective drives in its Tau underground mine, part of its Mupane operation near Francistown in Botswana, have led to the discovery of the potential extension of the Tau orebody at depth.

As part of the company’s recent review of historical exploration data, anomalous mineral intersections were observed as they were structurally displaced from the main Tau orebody and sub-outcropping beyond the interpreted Western dyke limit of the Tau orebody. A prospect drive was mined at the 820RL level (170 m below surface) to investigate the anomalous mineral intersection, and a mineralised zone (C Reef) was intersected.

Since the first intersection of the C Reef, a total 265 m of on reef development has been completed on three consecutive levels to determine the strike extent of the reef. At 820RL the strike extent was found to be 60 m; at 800RL the strike extent increased significantly to 135 m; and at 780RL Galane is currently mining along strike and a total of 70 m of strike has been exposed.

On the 820 and 800 levels, the C Reef widths varied along strike from a minimum of approximately 2 m up to a maximum of 7 m; from the development channel sampling, the intersected grade on the 820 level was 4,78 g/t and on the 800RL level 2,51 g/t. At 780RL the intersected grade is 3,66 g/t for the 70 m of exposed strike length. Further to this, at 780RL the C Reef has also widened significantly to a width of approximately 15 m.

To date, a total of 19 380 tonnes of ore has been extracted from the C Reef horizon at an average mined grade of 3,44 g/t.

The ore mineralisation characteristics of the C Reef are similar to those of the main Tau orebody; being a ‘disseminated style’ of mineralisation in well bedded, silicified quartz rich parts of the graphitic iron formation.

An exploration programme is being planned to start in 2017 to investigate if there is a down dip and the possible extent of the C Reef strike beyond the current mined area within the active underground working areas. There has yet to be sufficient exploration on the C Reef to extrapolate that the C Reef extends beyond the current mined area.

Galane Gold CEO, Nick Brodie commented: “This could prove to be a significant discovery and of potential importance for the long term future of Mupane once more studies and economic analysis can occur and be reported on. We had planned to start looking for the potential extension of Tau at depth in 2017 and so this was a positive surprise to intersect the potential extension so early and therefore be in a position to incorporate it into our current mining plan. If through further exploration and analysis we confirm that this is the extension of the Tau ore body at depth, it will be a further vindication of management's decision over two years ago to commence the underground operation.”
