Ashanti Gold Project Update on Anumso, Ghana
12.10.2017 | GlobeNewswire
Broader and New Mineralized Zones Identified; High Au Recoveries on Gravity (72%) and Bottle Roll Tests (99%)VANCOUVER, Oct. 12, 2017 - Ashanti Gold Corp. (“Ashanti” or “AGZ” or the “Company”) - (TSXV:AGZ) is pleased to provide an update at its Anumso project (the “Project”) and announce exciting new target discoveries made from its recently completed and assayed soil grab samples. Ashanti’s new soil sample results, testing previously underexplored areas, have encountered multiple parallel mineralized zones which are in aggregate up to 480m in wide in certain areas of the mineralization on the Project. Ashanti is set to apply its analysis of this new data to guide further exploration on the Project by trenching and drilling. Additionally, preliminary metallurgical test work on Anumso material show very encouraging results with high levels of gold recovery.

Tim McCutcheon, CEO, commented: “New opportunities for gold mineralization and the understanding that the material at Anumso has favorable gold recovery characteristics is great news for the Company.”
Soil Sample Program Identifies New Target Zones at Anumso
A soil sampling program consisting of approximately 1200 samples collected at 20m intervals along lines 200m apart along 10.3 km of strike exposure of Banket conglomerate was conducted in August to September, 2017. This program revealed multiple mineralized zones of mineralized Banket conglomerate (Figures 1 and 2). These zones are reflected in soil samples containing in excess of 30 ppb Au with 24 samples containing more than 100 ppb Au. Additionally, the most prolific portion of mineralized stratigraphy was not tested with drill holes historically and the strongest gold in soil results on several sample lines have never been tested in the subsurface (Figure 3) with any drill holes.
Figure 1. Map of the Anumso Mining Lease showing the location of soil sample lines and gold values for each sample. Results indicate the presence of multiple lines of mineralization over aggregate widths of up to 480 m rather than a single stratigraphic unit that hosts gold.

Figure 3. Detailed view of orientation soil line across the mineralized zone previously tested with historic drill holes. The gold values in soil samples exceed 100 ppb over a width of >70m in an area untested by historic drilling for >200m along strike. Note other lines of anomalism which remain to be drill tested.
Preliminary Metallurgical Test Work for Anumso Mineralized Material
The Company is very pleased to announce positive results for initial metallurgical studies on oxidized and unoxidized mineralized samples from Anumso. Samples were shipped to Blue Coast Research in Parksville, B.C. Canada for grindability and gold recovery tests. Two composite samples consisting of 41 kg of oxidized material grading 1.07 g/t Au and 158 kg of unoxidized material grading 1.46 g/t Au were submitted for tests to determine grindability, gravity recovery, and cyanide leach recovery of gold. Basic cyanidation testwork was conducted on six additional variability composites that ranged in grade from 0.29 g/t to 5.36 g/t.
Cyanidation tests were conducted as standard 48 hour bottle roll tests. During these tests 1000 grams of sample was added to a bottle along with water to 40% solids. Sodium cyanide (NaCN) was added according to the test protocols, generally at 1.0 g/L of solution. Kinetic checks were conducted after 2, 6, 24 and 48 hours to measure gold recovery and reagent consumption.
Results are very encouraging. Bond Ball Mill Work Index tests indicate the oxidized and unoxidized material is soft to moderately hard (Table 1). Excellent gold recovery by cyanidation (Table 2) was observed. An initial Extended Gravity Recoverable Gold (EGRG) test was conducted on the unoxidized composite which indicates that up to 72.9% of the gold may be recoverable by gravity methods. These are initial tests and further work to optimize process conditions and evaluate variability is planned.
