Exploration & Development
Mupane Gold Mining (Pty) Botswana holds prospecting licenses and mining licenses covering the entire prospective area of the Tati Greenstone Belt in Botswana. The Tati Greenstone Belt is part of the Zimbabwe Craton, a prolific area for gold production that has produced over 77 million ounces of gold historically.
In 2018 Galane signed a joint venture with B2 Gold on its prospecting licenses at Mupane. They key features are: -
- Earn in Agreement signed with B2 Gold on Prospecting Licenses for extensive exploration of the prospecting licenses
- B2 Gold to spend $4m over 3 years for 70% of the joint venture
- Targeting a 1moz+ resource
- Over 120 exploration targets have been generated from soil geochem and aero-magnetics work carried out
- Mupane will continue to focus on exploration on mining licenses which are not part of the JV, including Tau Deeps

Future Ore Sources and Current Exploration Targets
A Measured and Indicated resource of over 90,000 ounces was declared as of December 31, 2012. The gold mineralisation occurs in banded iron formation ("BIF") rocks hosted by other meta-sedimentary and meta-volcanic rocks equivalent to the Lady Mary formation of the Tati greenstone belt. The mineralisation is from surface, the BIFs forming a positive topographic feature. We have produced a conceptual mine plan, based on $1,400 gold, which could mine 680,000 tonnes of ore at an average grade of 2.16 g/t at a stripping ratio of 5.5. Our exploration program has identified a further 10km of strike and the current resource is based on a drill program that covered only 830 metres. The project is located 25 km to the west of the Mupane plant and is connected by existing gravel roads.
Map Nora (Shashe Mine)
Phelps Dodge commenced gold mining operations at Map Nora in the 1980s and continued into the early 1990s. Production was impeded by the refractory nature of the ore and failed due to metallurgical complexities. The metallurgy of such deposits is now far better understood and management is optimistic that a sellable concentrate from Map Nora could be produced
The Map Nora location features high grade shoots (>10g/t) that are continuous down plunge allowing for a Resource of the order of 100,000 to 150,000 ozs to a 300m vertical depth. The potential exists for 200,000ozs for every 300m vertical depth tranche.
Underground infrastructure, including headgear and winder, are in place and in good order to 340m vertical depth.
Matopi was a virgin discovery by Galane Predecessor company Gallery Gold in 1997 as a coincident Gold and Arsenic in soil geochemistry anomaly. Preliminary trenching and drilling show a large but low grade and discrete Ultramafic unit with uniform mineralization e.g. 35m @ 0.85g/t (including 4m @ 2.25g/t) and 41m @ 0.86g/t (including 16m @ 1.85g/t).
Orapa Road Anomalies
The Orapa Road Anomalies are a string of subtle Gold in soil geochemical anomalies sporadically developed over a strike length of 20 km and coincident with a strong linear aeromagnetic geophysical anomaly typical of a significant fault system. This group of anomalies potentially constitutes a classic case of gold 'leakage' up and along a structural system and could be indicative of significant gold mineralization at depth.
The Ore bodies that have been historically mined as open pits are open, with the grade typically higher, at depth. The nature of the ore bodies at depth will be studied in the context of the economic viability of underground mining. Planning has commenced for exploration drilling at depth for Signal Hill, Golden Eagle, Tau and Kwena.
We have also started exploration underground at Tau to try and confirm the extension of the ore body beyond the current known strike length. In addition, we have also commenced prospect drives to look for ore body extension and allow for depth extension drilling.
