High Grade Results at M1 Prospect 9m at 7.8g/t Au Including 4m at 16.9g/t Au from 8m Ending in Mineralisation
Highlights
- RC drilling at M1 prospect intercepts shallow oxide mineralisation
- Drilling provides potential to add ounces and increase grade to heap leach starter project
- Follow-up RC drilling planned to commence in October
Managing Director Richard Hyde commented:
“9m at 7.8g/t Au from only 8m at the M1 prospect shows there is potential to add ounces and grade to our heap leach starter project from nearby targets. M1 mineralisation will be incorporated resource inventory later this year.
“First pass drilling is in progress at the M2 and M3 prospects. Follow-up drilling at M1 will commence in October after the current wet season.”
RC drilling at the M1 prospect has intercepted shallow oxide mineralisation along strike from historic high-grade gold mineralisation at depth (Figure 1 and 2). Shallow first pass RC drilling focussing on oxide mineralisation has been completed with an Aircore rig drilling to blade refusal; as such TAC0891 ended in quartz veining returning 9m at 7.8g/t Au including 4m at 16.9 g/t Au from 8m. It is expected that oxide mineralisation from M1 will exhibit similar metallurgical characteristics to M5 oxides, and will be amenable to heap leach processing.
None of the gold mineralisation at the M1 prospect is currently included the project resource inventory. M1 mineralisation will be modelled and incorporated in a resource update later this year, and subsequently added to the mine schedule. Any additional higher grade oxide tonnes will have a positive impact on the project economics. First pass shallow RC drilling targeting oxide mineralisation at M1 has been completed, with initial results including:
- TAC0856: 10m at 1.04g/t Au including 1m at 5.04g/t Au from surface
- TAC0864: 5m at 1.01g/t Au from 26m
- TAC0865: 15m at 0.73g/t Au from surface
- TAC0887: 10m at 1.44g/t Au from 8m, including 2m at 4.92g/t Au*
- TAC0891: 9m at 7.8g/t Au from 8m, including 4m at 16.93g/t Au*
- TAC0933: 2m at 0.84g/t Au from 8m*
- TAC0991: 4m at 0.83g/t Au from 20m*
* denotes ended in gold mineralisation
Follow-up RC drilling is planned to commence in October after the current rainy season. This drilling will properly test mineralisation beneath historic artisanal workings and recent strong auger results with deeper >50m RC hammer and diamond core drilling. An updated cross-section of through M1 and a summary plan showing results from recent drilling is shown below in Figures 1 and 2, with results presented in Table 1.

The company is fully funded by Macquarie Bank (ASX, TSXV: 22/12/14) to complete a Feasibility Study for a heap leach starter project by Q3 of this year, which will incorporate any positive results from ongoing exploration programs. Follow-up RC drilling is underway and results will be reported as they are received by the company.
2015 PFS Highlights
West African Resources Limited completed an updated Pre-Feasibility Study report for an oxide heap leach starter project on its Mankarga 5 Gold Project, Burkina Faso in May 2015 (ASX, TSXV: 15/5/15, 29/5/2015). It was prepared in accordance with the requirements of both the Australian 2012 JORC Code and Canadian NI 43-101. The report is filed on SEDAR and on the Company’s website. A summary of the base case is stated below assuming a 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
- Probable 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:
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.
Production targets for the proposed heap leach starter project referred to in this announcement were first released to the ASX and TSXV on 23 February 2015. They are preliminary and there is no certainty that the production targets, or the forecast financial information derived from the production targets, will be realised. All material assumptions underpinning production targets or forecast financial information derived from production targets continue to apply and have not materially changed.
