• Acquisition of large, highly prospective Miradani Project, adjacent to the Asanko Gold Mine
• Miradani Project sits on an existing mining lease, which will enable potential mineral resources to be accelerated to production
• Historic trenching results include individual 1.5m trench samples assayed up to 47.3 g/t, which indicate significant grade intersections
• Based on historic trenching and extensive artisanal workings, huge potential to increase Asanko’s resource base within trucking distance of the processing facility
• Three main targets identified, Miradani, Central, and Tontokrom, extending over 800m, 320m and 850m respectively, consisting of multiple mineralized zones of up to 37m each in width
• Drilling program on Miradani, Central and Tontokrom to commence in Q4 2017
• Targeting maiden Mineral Resource Estimate in H2 2018
Vancouver, British Columbia, September 22, 2017 – Asanko Gold Inc. (“Asanko” or the “Company”) (TSX, NYSE American: AKG) is pleased to announce it has acquired ownership of the Miradani Mining Lease (the “Miradani Project”), which is adjacent to the Asanko Gold Mine (“AGM”) in Ghana, West Africa (see Figure 1) from AngloGold Ashanti. Acquisition costs of the Miradani Project, which bear standard Government of Ghana royalty interests, are not disclosed and are not material.
Covering an area of approximately 15 km2, the Miradani Project is on an existing mining lease (valid until May
2025) which will enable potential mineral resources to be accelerated to production. The northern boundary of the concession is located approximately 5.5 km south of the AGM’s processing plant on the NE-SW Asankrangwa structural corridor. The underexplored Asankrangwa Gold Belt is about 7 km wide and over 50 km long. The area is highly prospective with multiple geochemical anomalies aligning with the structures interpreted from the airborne VTEM and magnetic surveys completed by Asanko in 2015. Asanko holds the largest land package on this Belt and it hosts all of the Company’s 5.1 million ounces of reserves (see Figure1).
Three significant initial target areas along the main structural trend, Miradani, Central, and Tontokrom, have been identified. A phased drilling campaign is expected to commence in Q4 2017, with a view to completing a maiden Mineral Resource Estimate in H2 2018. Historical trench and soil geochemistry data, along with recent mechanized artisanal mine workings, indicate that each target area consists of multiple parallel mineralized zones, individually ranging between 3m and 37m in width. Individual 1.5m trench samples assayed up to 47.3 g/t.
Commenting on today’s announcement, Peter Breese, President and CEO, said “The Miradani Project is a very exciting exploration project with huge potential to increase our resource base and contribute to our future growth. Located next to our current operation and within trucking distance, the Miradani Project comes with the advantage of being on an existing mining lease, which means that we will be able to accelerate the development timeline from resource delineation to production.
Historic trenching indicates there are at least three main zones of mineralization across the project area and the extensive artisanal workings confirm gold is present. We have identified three drill ready targets which we will start to drill in the coming quarter and we look forward to updating the market further during H1 2018.”
The Asankrangwa Belt is defined by NE-SW trending primary and secondary lineaments providing conduits for gold bearing fluids and sites for metal deposition. The Miradani Project is underlain by the lower Birimian system (metasediments) of the Kumasi Basin generally consisting shallow marine of siltstones, sandstones, shales and volcaniclastics, and are intruded locally by sizeable mica-rich granitoid plutons. The metasediments are regionally metamorphosed to greenschist facies and sometimes host disseminated sulphides and carbonates. Pyrite, the most prevalent sulphide, is most often oxidized to limonite or leached out leaving cubic casts. Metasediments of the Kumasi Basin have well developed schistosity parallel to bedding and striking northeast usually between 25° - 35° and often dip steeply to either northwest or southeast.
Gold deposits found on the Asankrangwa Gold Belt are shear zone hosted orogenic gold deposits. Gold mineralization is generally free gold within quartz carbonate veins hosted within marine sediments and smaller granitic intrusions coincident with the structural corridors. Deposits generally occur at or near intersections of deep crustal primary and secondary shear zones, or in flexures in the shear corridors. The structural architecture and controls on mineralization of the Asankrangwa Belt has been extensively studied and interpreted by Asanko. This understanding forms the basis for all prospectivity studies and exploration targeting.
Major primary shear structures pass through the Miradani Project and the target areas are located at the intersection of secondary structures. These primary structures are parallel to similar structures hosting all of the other AGM deposits. The SW (Miradani), Central, and NE (Tontokrom) portions of the Miradani Project are highly prospective and contain extensive historic gold in soil anomalies and fall at areas of structural complexity. In addition to the Miradani targets, multiple other high priority exploration targets have been identified in areas of coincident structural complexity and geochemical anomalies (see Figure 2). Three walk up drill targets have been clearly defined from historic trenching and soil geochemistry results as well as intensive mechanized artisanal mining.
