3.2 Ghana Geological Survey (early 1960’s)
The Ghana Geological Survey carried out trenching and diamond drilling around the deposit in the early
1960’s. A total of 11 holes were drilled below the workings down to 200m below shaft collar.
"Core losses
were considerable and the core size was probably only BX or BXT. The ensuing poor results have often been
considered as highly unreliable due to the poor core recoveries."
3.3 Atwima-Amanano Goldfields Ltd (1992) & Gencor (1992-1994)
Atwima-Amanano Goldfields Ltd. acquired the License in February 1992. Gencor Mineral Resources explored
the license on behalf of Atwima-Amanano Goldfields from October 1992 to March 1994. Apart from surface
geochemical sampling, the old stopes of the Bibiani North Mine were sampled. Gencor concluded that the
mineralisation at the Bibiani North Mine was related to quartz veins and disseminated sulphides in
metasedimentary and metavolcanic rocks. Gencor terminated this agreement with Atwima-Amanano
Goldfields Ltd in 1994
3.4 Echo Bay (Ghana) Limited (1994)
In 1994 Echo Bay (Ghana) Limited, a fully owned subsidiary of International Gold Resources, obtained the
exclusive option to acquire 100% of Atwima-Amanano Goldfields Limited after submitting a positive
feasibility study.
A blanket soil geochemical survey was carried out and striking soil anomalies were delineated over the
Bibiani North ore body (herein referred to as the Ekom Eya Permit). Ekom Eya Small Scale Permit, Bibiani, Western Region, Ghana PGS 143

Echo Bay (Ghana) Limited diamond drilled a total of 12 holes in early 1995. Seven holes were drilled into and
around the old Bibiani North Mine. The best results were 49.4 g/t over 2.2 meters and 19.8 g/t over 2.65
meters. These intersections clearly indicated that there are very rich gold shoots within the broad shear
zones.
The drilling indicated that there are high grade remnants left around the old workings together with the
possibility of a continuous ore body between the high grades shoots of around 5-6g/t. This could make
Bibiani North a viable prospect both as an open pit and an underground operation.
The remaining five holes intersected gold values less than 1 g/t, although these were drilled into the old
workings.
NOTE: Drilling into old workings is inherently difficult with substantial water losses whenever the old
workings are intersected, plus substantial core losses, so the above Echo Bay drilling campaign would have
only given an indication of the gold potential within this permit.
Two holes were drilled over VLF anomalies to the west of Bibiani
