Desert Gold's exploration methodology has yielded tangible results in Rwanda. The Byumba Concession, started as a grassroots project in February 2008, has yielded Rwanda’s first ever compliant gold resource statement. The 2008 – 2009 drilling campaign outlined a Canadian NI 43-101 and SAMREC compliant inferred resource of 265 000 oz Au at an average grade of 1.5g/t gold.
Modelling of the 2008 – 2009 drill data provides an inferred resource of 265 000 oz Au. Higher grade zones of mineralisation occur within broad low grade envelopes. The mineralised zone is hosted within fairly steep dipping bedding parallel zones. Using a 0.5g/t cut-off shows 14 higher grade zones. These zones have strike lengths varying from 100m to 1600m. Drilling tested the mineralisation to a maximum vertical depth of 200m. The thickness of the higher grade envelopes vary in thickness from 1m to 8m with low grade separation between the shells varying from 3m to 15m.

Upside potential on the Byumba Project
Desert Gold believes that drilling of exploration targets down dip and along strike will increase the resource significantly. Mineralisation is open down dip and along strike. Gold grades increase with depth from 1.2g/t in the oxide zone to 1.7g/t in the sulphide zone. During the fourth quarter of 2011 four more holes were drilled along strike to the north – northwest. These prove mineralization to continue along on a north – northwest trend. Drilling to the north-northwest is continuing to increase the gold resource by following mineralization along strike.
