Alahiné encompasses an area of 64km2. A soil program was successful in delineating broad zones of gold anomalism along the eastern side of the licence and a significant number of single and multiple-station highly anomalous sites across the licence.
As defined by soil sampling during 2018 and 2019, there are three areas with significant gold anomalism extending over approximately 8 km in length. Additionally, twelve single station anomalies with >1000 parts per billion (ppb) gold and 8 anomalies with 500 to 1000ppb gold elsewhere in the licence must be further progressed. The very high gold values (>1000ppb) are not the result of contamination from artisanal activities. All soil samples were collected from depths of 200 to 300mm beneath the ground surface are an accurate reflection of the natural abundance of gold in the soil at a given sample location.
There are also substantial areas of lateritic cover which may conceal zones of structurally hosted vein mineralisation and supergene enriched or basal laterite hosted gold, in which investigation works will follow.
The Phase 2 program has focussed on:
- Follow-up of mineralised intercepts from the Phase 1 drilling program,
- Follow-up of the best soil-Au anomalies not yet tested, and
- Investigation of intense artisanal mining activity.
The Phase 2 program has focussed principally on shallow supergene gold resources within the weathered zone, but high gold values (eg. 21.40 g/t Au in hole AH21ARC065 and 11.56 g/t Au in hole AH21ARC075) encountered at Air Core refusal hints at deeper potential. Similarly, intense artisanal activity recovering high grade gold from shallow depth implies a gold source nearby. Potentially deeper, unweathered portions of that source are an important target.
Very similar geology has been encountered over the strike length tested. Deep but variable weathering ranging from 50 to 100m vertical depth has been encountered. The nature of the lateritic profile is unclear at present, but appears to comprise auriferous lateritic gravels overlying a well-developed mottled zone which gives way to intensely bleached saprolite, saprock then fresh rock.
The supergene gold content of the near surface lateritic gravels is variable, but values of 1m at 51.73 g/t in hole AH21ARC094 and 1m at 96.00 g/t in hole AH21ARC095 are significant.
With a strike length in excess of 4km and with drill traverses spaced at 500m intervals, numerous anomalous responses remain untested.
