West African Resources Extends Mankarga 5 Trend by 1.5km with up to 0.63g/t Au in Auger Drilling
16.06.2015 | FSCwire
Perth, Australia (FSCwire) - Gold developer West African Resources Limited (ASX, TSXV: WAF) is excited to announce significant results from auger drilling along strike of the Mankarga 5 deposit, Tanlouka Permit Burkina Faso.Managing Director Richard Hyde commented:
“Auger drilling along strike from the proposed open pit has delivered strong results with a peak of 0.63g/t Au. The gold anomaly over this previously untested zone is similar in grade and tenor to auger results over the existing Mankarga 5 resource area.”
“RC drilling has commenced over the extension of Mankarga 5, and results will be reported as they are received by the Company.”
Mankarga 5
Auger drilling along strike to the northeast of the Mankarga 5 (M5) deposit has delivered strong results demonstrating the continuation of mineralisation along strike of the proposed oxide starter pit that the Company intends to treat by conventional heap leach processing (Figures 1 and 2).
Importantly the results from the recent WAF auger shows that the geochemical signature over known mineralisation is subtle and discreet with only seven samples greater than 160ppb Au within the proposed starter pit outline. Results along strike of the M5 resource demonstrate that there is significant potential to add more oxide tonnes to the heap leach starter project and extend the current PFS mine life of 7 years.
In total 245 auger holes, with an average depth of 5.3m, were drilled along strike of the M5 resource area on lines oriented northeast - southwest, on a 200m by 50m grid. Sampling returned a peak result of 635 ppb Au (0.64g/t Au) with other high tenor results of 228 ppb Au, 224 ppb Au and 218 ppb Au (Figure 2)
Mankarga 1
Mankarga 1 (M1) is the most advanced prospect and located approximately 500m northwest of the Mankarga 5 Mineral Resource (Figure 1). Infill auger drilling has been completed at the prospect. M1 has significant potential to add additional oxide tonnes to the proposed heap leach starter project. The major difference in this area is that mineralisation trends north-northwest, in contrast to Mankarga 5 which trends northeast. Regional sampling on sub-optimal northwest-southeast lines returned high tenor results including 661 ppb Au (0.66g/t Au), 380 ppb Au, 568 ppb Au, 301 ppb Au, 368 ppb Au and 297 ppb Au.
Results are imminent for detailed auger drilling completed on a 25m by 100m grid, oriented on northeast-southwest lines perpendicular to the main northwest mineralised trends as shown in Figure 1. WAF geologists have completed detailed prospect and structural mapping of the area and noted that the area comprises similar rock types and stratigraphy to M5. Mineralisation is hosted with steeply dipping quartz veining which has been subject to significant artisanal mining activity (Figure 3 & 4) with pits down to 30m depth. Significant results from historic drilling at Mankarga 1 are shown in Table 1 below. Results of infill auger drilling will reported as soon as they are received. A contract RC rig will will be used to test the area as soon as results are received.

2015 PFS Highlights
West African Resources Limited announced results of its technical and financial assessment of an oxide heap leach starter project on its Mankarga 5 Gold Project, Burkina Faso in May 2015 (ASX, TSXV: 29/5/2015). This assessment constituted a Pre-Feasibility Study (PFS) incorporating updated Mineral Resource, mining schedule, column test work and cost inputs. It was prepared in accordance with the requirements of both the Australian 2012 JORC Code and Canadian NI 43-101. A summary of the base case is stated below assuming 100% project at a gold price of $1,300/oz. All amounts are in US dollars.
- Production of 69,000oz pa for first 3 years, 49,000oz pa for life of mine, 7 year life of mine
- Cash costs $428/oz for 3 years, $635/oz life of mine
- All-in cash costs of $538/oz for 3 years, $749/oz life of mine
- Pre-tax IRR of 63% with 14-month payback, post-tax IRR of 50% with 16-month payback
- Pre-tax cash flow of $146m, post-tax cash flow of $118m after initial and sustaining capital costs
- Pre-tax NPV5% of $117m, Post-tax NPV5% of $86m
- Indicated Ore reserve of 440,000oz, life of mine strip ratio 2:1
- Potential to upgrade in-pit Inferred Resources currently treated as waste in mining schedule
- Nearby drill ready oxide targets with potential to add to the base case

Cautionary Note About Mineral Resources:
Mineral Resources that are not mineral reserves do not have demonstrated economic viability. Mineral resource estimates do not account for mineability, selectivity, mining loss and dilution. These mineral resource estimates include inferred mineral resources that are normally considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is also no certainty that these inferred mineral resources will be converted to measured and indicated categories through further drilling, or into mineral reserves, once economic considerations are applied.
