Volcanic Gold Mines Inc. is pleased to report on the progress of exploration drilling at its Mandiana Project, as well as at the contiguous lands recently acquired under option from West African Mining Associates SARL in Guinea.
A total of almost 3,000m of reverse-circulation and diamond drilling, and over 6,000m of air-core drilling have now been completed at these projects. A high-resolution airborne magnetic survey over the projects, to be flown at 50m line spacing and low sensor clearance, is expected to commence during the month of June. The purpose of this survey will be to provide important targeting information associated with known mineralized trends.
Volcanic's reverse-circulation and diamond drilling is being conducted both within, and in the immediate surroundings of, the Inferred Mineral Resource (the "Mineral Resource") at the Yagbelen deposit at Mandiana, as previously defined by Sovereign Mines of Africa plc ("Sovereign"). As well as serving to infill the Mineral Resource, the purpose of drilling is to gain vital information on the geological controls on mineralization, as a basis for targeting further resource drilling activities later in 2017.
Reverse-circulation drilling of the Farabakoura target at the WAMA Project has also been advanced, its purpose being to confirm the high grade historic results announced by Volcanic on April 18, 2017 and described below. Air-core drilling is also ongoing at the WAMA Project, and has to date been deployed in exploration of strike and lateral extensions to mineralization to the north, east and south of the Yagbelen Resource, and in a similar fashion along a north-south axis characterized by artisanal working and high grade historic drilling intervals at Farabakoura. Drilling is being performed in a series of "fences" established at 100-200m intervals, along which inclined holes are drilled at 40-50m spacings. This rapid, low-cost approach to exploration has been designed to provide detailed and accurate information on near-term resource targets.
Drilling results are awaited, and will be reported upon in due course.
About the Mandiana and WAMA Projects
In January 2017, Volcanic acquired a 75% interest in the Mandiana Project. The remaining 25% interest in the Mandiana Project is held by SOGUIPAMI, a Guinean government-owned business entity formed to conduct mineral exploration projects. In April 2017, Volcanic entered into a binding letter agreement to earn-in to an 80% interest in the WAMA Project which adjoins the entire length of the southern boundary of, and lies within the same mineralized trends as the Mandiana Project.
The Mandiana and WAMA Projects are underlain by geology comparable to that of many other Birimian-age volcano-sedimentary sequences in West Africa, in which gold mineralization typically exhibits a strong relationship with major structural and hydrothermal zones. At both the Mandiana and WAMA Projects the gold mineralization associates with a network of quartz veins which appear to relate to such zones, and is located at major lithological and structural breaks. In the near vicinity and of very similar geological character is AngloGold Ashanti's Siguiri Gold Mine (Measured and Indicated Resources of 3.37 Moz Au and Inferred Resources of 2.14 Moz Au). Other significant gold deposits and mines in the neighbouring area include Hummingbird Resources' Yanfolila project, Avnel's Kalana property, and Avocent's Tri-K project.
Of key importance at the Mandiana and WAMA Projects is the presence of shallow but extensive artisanal workings in the project area, which are seen to follow the north-south mineralized trend common in known deposits in the vicinity. Limited drilling beneath such working by both Sovereign and WAMA led to the identification of bedrock gold mineralization. Many kilometers of artisanal workings on these trends remain to be drill tested.
Prior to cessation of work activities due to a shortage of market funding in 2013, Sovereign drilled 119 RC and diamond drill holes for a total of 16,624 meters at Mandiana, includingthe four zones (Yagbelen, Foulouni, Damantare and Woyondjan) that form the basis of the Mineral Resource calculation, as well as at other features. Results of Sovereign's drilling programs completed between 2011 and 2013 include:
- RCY07 - 28m @ 1.66 g/t Au from 103m
- RCY36 - 30m @ 3.15 g/t Au from 35m
- RCY37 - 40m @ 4.49 g/t Au from 150m
- RCY88 - 18m @ 1.93 g/t Au from 144m
- RCY89 - 12m @ 2.89 g/t Au from 73m, and 19m @ 2.58 g/t Au from 104m
- RCY114 - 28m @ 6.44 g/t Au from 168m with a top cut of 30 g/t Au
One of the most notable mineralized occurrences within the WAMA Project is the Farabakoura deposit. During 2014 and 2015 WAMA drilled 89 inclined RC holes beneath lateritic artisanal workings at Farabakoura, results1 of which include:
- FKRC003 - 7m @ 28 g/t Au from 64m (visible gold observed in RC chips)
- FKRC005 - 12m @ 39.1 g/t Au from 68m (visible gold observed in RC chips)
- FKRC006 - 6m @ 13.8 g/t Au from 74m
- FKRC035 - 4m @ 5.2 g/t Au from 52m and - 6m @ 13.9g/t Au from 68m
- FKRC037 - 3m @ 8.1 g/t Au from 77m
- FKRC071 - 7m @ 102.5 g/t Au from 62m (visible gold observed in RC chips)
- FKRC074 - 6m @ 16 g/t Au from 71m
- FKRC075 - 6m @ 5.7 g/t Au from 69m
- FKRC076 - 6m @ 17.2 g/t Au from 81m
- FKRC087 - 6m @ 64.8 g/t Au from 43m
The weathering profile at the property extends in places to depths in excess of 200m from surface, producing friable, oxides material which beneath the lateritic profile is very easy to dig.
