Geology
The geology of Southwest Ghana is dominated by the Birimian Supergroup metasedimentary and metavolcanic rocks and various granitoid intrusions. Granitoid intrusions are subdivided into two types: Belt Type (Dixcove) granitoid and Basin Type (Cape Coast) granitoid. Belt type granitoids (ca. 2180 Ma, Allibone et al. 2004) possess a metaluminous character, are often tonalite to granodiorite and are confined to Birimian metavolcanic belts (Hirdes and Leube 1989). Basin granitoid (~2116- 2088 Ma, Allibone et al. 2004b) have a peraluminous character and higher K and Rb relative to belt granitoids, are mainly granodiorite, and associated with the central portions of Birimian metasedimentary basins (Hirdes and Leube 1989).
Within the Birimian Supergroup, northeast striking mafic metavolcanic belts are separated from intervening metasedimentary (dominantly turbiditic) basins by major faults. These faults probably controlled early syn-Birimian sedimentary basin down-faulting (Hirdes and Leube 1989). The two largest and best known of the Birimian metavolcanic belts are the Ashanti Belt and Sefwi-Bibiani Belt.
Dating of granitoid rocks (Belt Type granitoids) that cut the Birimian metavolcanic rocks constrains the age of these rocks as greater than ca. 2186 Ma. Detrital zircons in the Birimian metasedimentary rocks yield U-Pb ages between 2187and 2130 Ma, indicating deposition of both units occurred after 2130 Ma. Granitoid rocks (Basin type) that intrude the Birimian metasediments and Tarkwaian Group have U-Pb zircon ages of ~2116 to 2088 Ma, which indicates deposition of both sedimentary packages occurred prior to 2116 Ma. Allibone et al, (2002) suggest that the compression, polyphase deformation and metamorphism of all Birimian rocks happened contemporaneously with the intrusion of basin type granitoid rocks and probably reactivated the Belt bounding faults as thrust faults. U-Pb geochronology on ore-related titanite in the Ashanti deposit indicates that gold mineralisation occurred at ca. 2100- 2090 Ma(Oberthür et al. 1998), at the later stages of this event. Allibone et al, (2002) suggests that the last phase of deformation was predominantly sinistral strike slip faulting resulting in ore-hosting shear zones.
The Sefwi Belt is one of Ghana’s largest belts volcanic belts with prominent gold deposits on the northwest and southeast margins. The Belt consists of extensive mafic volcanic rocks and widespread Belt-type dioritic intrusive bodies, some of which host gold mineralization as at Newmont’s Ahafo Mine along the northwest margin of the belt. Here gold is being produced from 4 individual open pit operations. Along the southeast margin, the Mine and Miner occur along structures that form the sheared margin of the belt. Tarkwaian rocks occur along the margin of this belt near the Chirano Mine.
2022 Work Program
There are two types of mineralization and gold occurrences that are of economic interest on the property – alluvial and hard rock gold.
Alluvial Gold
Alluvial gold deposits form over time where a river runs, or has previously run through ground which is rich in gold. The erosive power of the water removes the surrounding rock due to its comparative low density while the heavier gold resists being moved. Alluvial gold usually takes the form of dust, thin flakes or nuggets. Our Kukuom property has several alluvial prospects that are currently being investigated for their economic potential.
Hard Rock Gold
Gold mineralization on the concession is dominantly concentrated in shear zones, hosted and often shown in association with foliated andesites, carbonated andesitic tuffs and cherts. This suggests intense hydrothermal alteration (silification and carbonatisation). Quartz veining is ubiquitous in the area. The carbonated andesitic tuffs host two small reefs in the area.
Summary
Our Kukuom Concession is therefore considered prospective for both alluvial and hard rock styles of gold mineralization.
Guskin’s priority 2022 work program includes further exploitation of a 247-hectare section with proven alluvial and hard rock gold occurrences.
Remote sensing surveys carried out over the property produced a strong priority target anomaly with a North to `South Axis measuring 1,170 meters and a West to East Axis 1,052 meters, or 1,230,840 sq/meters with an estimated 19’ thickness or approx. 6,293,109 tons of target material.
A three-phase work program is underway.
| Phase I | Removal of the lateritic overburden layer believed to contain approx. 0.8 gram / ton (on average) down to bedrock. Processing of the material to exploit alluvial gold which may fund continued hard rock studies. |
| Phase II | Hard rock exploration including a 17 hole drill program and further delineate hard rock targets either within or outside the confines of the known prospects. |
| Phase III | Expansion of the drill program outside the 247 hectare work session and begin exploratory drilling on high priority targets. |
