The 60 square kilometer Abansuaso Prospecting License, contiguous to and immediately south of Pelangio’s Manfo Project, covers the possible strike extensions of Pelangio’s Nfante, Nfante West and Nfante East mineralized zones. Pelangio’s Nfante West deposit, which sits at the southern end of the principal mineralized structure on the Manfo Project hosts a small portion of the total mineral resource at Manfo, estimated at 503,000 tonnes at 1.10 g/t Au (18,000 oz) in Indicated plus 663,000 tonnes at 0.80 g/t Au (17,000 oz) in Inferred categories. The total mineral resource estimate at Manfo currently stands at 3.97 million tonnes at 1.52 g/t Au (195,000 oz) in Indicated plus 9.67 million tonnes at 0.96 g/t Au (298,000 oz) in Inferred categories, hosted by the Nfante West, Pokukrom East and Pokukrom West deposits.
The Nfante West deposit, similar to the other deposits and mineralized zones at Manfo, is hosted in a metagranodiorite and is related to silica-sericite-dolomite alteration with associated quartz-dolomite veining plus disseminated pyrite. Weaker gold mineralization tends to be associated with hematite +/- sericite alteration. The mineralization at Nfante West dips steeply to the west at 70 to 80 degrees and is generally bounded by a brittle-ductile shear zone along the contact with mafic metavolcanics on the footwall side to the east. The Nfante and Nfante East mineralized zones are similar, weaker versions of Nfante West.
Diamond drilling of the Nfante West target by Pelangio in 2010 returned the best intercept in the first hole, SFDD-079, which returned 1.35 g/t Au over 70 meters (true width of 53 meters), including 3.03 g/t Au over 18 meters (true width of 13.5 meters). One of the follow up drill holes, SFDD-082, drilled at the southernmost end of the Nfante West deposit on Pelangio’s property boundary, returned 0.89 g/t Au over 41 meters (true width of 26 meters).
Anglogold Ashanti Limited, initially as Ashanti Goldfields Corporation, held the Manfo property (Subriso Prospecting License) from 2003 through 2005 and conducted conventional soil geochemistry surveys, trenching and 3,400 meters of RC drilling in 64 holes discovering most of the currently known mineralized zones on the Manfo Project. Some of their exploration work extended onto the current Abansuaso property along the Nfante West extension, with 4 trenches and 10 RC holes drilled on Abansuaso. Gold assay results from Anglogold Ashanti’s exploration on Abansuaso ranged from negligible (< 0.20 g/t Au) in two of the trenches and five out of the 10 RC holes drilled, up to high grade values in their southernmost trench SFTR015, which is located 900 meters southwest of Pelangio’s southernmost drilling and reportedly returned intervals of 4.03 g/t Au over 19 meters, 19.64 g/t Au over 5 meters and 14.32 g/t Au over 2 meters. An RC drill hole, SFRC011, designed to undercut the trench returned 1.04 g/t Au over 34 meters (true width of 27 meters) including 5.52 g/t Au over 4 meters (true width of 3.2 meters), and a second noteworthy RC hole, SFRC016, drilled 650 meters to the northeast, returned 1.52 g/t Au over 37 meters (true width of 32 meters) including 3.23 g/t Au over 6 meters (true width of 5 meters).
The data compiled from Anglogold Ashanti’s exploration activities comes from two reports filed with the Ghana Minerals Commission entitled: 1. Hebron Exploration and Mining Company Limited, Subriso Prospecting License, Terminal Report for the Period Ending July 2003 Prepared by Ashanti Goldfields Company Limited, and 2. Hebron Exploration and Mining Company Limited, Subriso Prospecting License, Technical Progress Report Fourth Quarter 2004, Prepared by Anglogold Ashanti Exploration. The second report contains the assay certificates for the RC drilling conducted by Anglogold Ashanti during this period, however the assay certificates for trench sampling are not in these reports. AngloGold Ashanti’s analytical work was conducted by Transworld Laboratories (now Intertek Minerals Limited), in Tarkwa, Ghana. Anglogold Ashanti’s sampling, sample preparation and QA/QC specifics are not known, however it is evident that their earliest efforts employed 24 hour 1 kg BLEG (Bulk Leach Extractable Gold, or “Bottle Roll”) for gold analysis, and they switched to 50g Fire Assay with AAS Finish for all gold analyses in 2004.
During the period from 2011 to approximately 2015, the Abansuaso property experienced considerable artisanal mining activity, at times utilizing heavy equipment, which resulted in a total area of approximately 18 hectares mined along three subparallel zones over a strike length of 1,500 meters and across a width of up to 800 meters. The artisanal miners worked oxidized elluvial (saprolitic) material and numerous hand-dug vertical shafts as deep as the water table (20-30 meters?) were excavated targeting quartz veining along the three mineralized trends, with processing by crushing and sluicing. Much of the mining activity was along the strike extension of the Nfante West deposit, with two mineralized trends apparent to the east, the easternmost of which appears to correspond to the strike continuation of the Nfante mineralized zone. The majority of the artisanal mining area has not been tested by drilling, and Pelangio has not sampled the mining stockpiles to verify gold tenor.
The historic artisanal mining activities and the previous exploration by Anglogold Ashanti have demonstrated the presence of three or more mineralized trends extending southwest from Pelangio’s Nfante and Nfante West prospects onto the Abansuaso property, identifying a high priority drill-ready exploration target area of approximately 2.5 kilometers in strike and 800 meters in width. Upon the finalization of the formal agreement with Supercare and necessary permitting, Pelangio intends to drill multiple fences of diamond and RC holes across the target area in order to rapidly assess the potential of the mineralized trends which were lightly tested by Anglogold Ashanti, possibly leading to resource definition drilling. A further 2.5 kilometers of strike of the trend to the southwest is covered by the Abansuaso property and will likely be evaluated with soil geochemical sampling as a first pass.
