Dumbwa A Tier-One Exploration Target • A near surface, low strip, large-scale exploration opportunity with very similar geology and mineralization to Barrick’s Lumwana Mine • Continuous high-grade copper-in- HISTORIC DRILLING soil anomaly for over 20 km along strike and ~1 km wide with peak values u
Slide 14: Vegetation-rich environment outside the soil anomaly
Outside of the 20 km copper-in-soil anomaly, Dumbwa is a vegetation rich environment, as seen here 14
Slide 15: Copper clearings over the soil anomaly
However, over the soil anomaly, exists vast “copper clearings”, which are a stark indicator of an underlying mineralized copper system. Soil toxicity, caused by the copper rich environment prevents most vegetation from growth 15
Slide 16: Bedrock exposure of high-grade sulphides
A large bedrock exposure of high-grade sulphides exists in the centre of one copper clearing at Dumbwa. One of only a few such surface exposures across the property 16
Slide 17: Surface samples of 3.0% Cu and 1.8% Cu
Samples taken by Dr. Bonel in this location resulted in 3.0% Cu and 1.8% Cu respectively 17
