Drilling commences at Hawiah Prospect in Saudi Arabia
KEFI Minerals (AIM: KEFI), the gold exploration and development company with projects in the Federal Democratic Republic of Ethiopia and the Kingdom of Saudi Arabia, is pleased to provide an update on exploration activities at the Company's Hawiah Exploration Licence in Saudi Arabia.
Drilling rig and team have been mobilised to Hawiah for a programme designed to test the extent of the gold mineralisation in the upper oxidised zone as well as for a significant subsurface copper-gold-zinc deposit.
This will be an initial 2,500 metre scout drilling programme along what is currently judged to be the most prospective portion of the gossanous ridgeline at Hawiah. Previous work has shown that this area is enriched in gold and has abundant secondary copper showings. Geophysical surveys have identified a strong and continuous anomaly under this ridge that indicates massive sulphide mineralisation is likely to be present 50-300 metre below the ridge.
Hawiah is located in Saudi Arabia's Wadi Bidah Mineral District which is a 120-kilometre-long copper-gold-zinc VMS belt where over 24 VMS occurrences were defined by the US Geological Survey and French Geological Survey over many years of research.
Hawiah is one of KEFI's higher priority prospects as the geological setting is analogous to other large VMS deposits in the Arabian-Nubian Shield that have well-preserved, mature oxidised zones enriched in gold at surface.
Initial surface exploration has confirmed that the main gossanous ridgeline is enriched in gold and the mineralisation has good continuity along strike and has abundant secondary copper showings. KEFI's Self Potential ("SP") and induced polarisation ("IP") geophysical surveys indicate it is underlain by a large and continuous conductive body.
In February 2015, KEFI completed a first-pass, wide-spaced trenching programme over the gossanous horizon. KEFI's trenches repeated all of the BRGM's trenches, as well as extending the known (4.5km) exposure to the south and to the north. All of KEFI's trenches contained anomalous gold, including 6m at 2.2g/t gold, 2m at 8.7g/t gold, 6m at 1.9g/t gold, 3m at 5.8g/t gold, 2m at 7.5g/t gold and 8m at 3.0g/t gold.
The southern area of the Hawiah ridgeline presents with the highest base metals in trench assay as well as the strongest geophysical responses. For these reasons, this area is the priority for the initial drilling program.
