West African gold explorer, Golden Rim Resources Ltd (ASX: GMR) has identified a major geophysical anomaly which it believes coincides with high-grade gold hits at the Kouri Gold Project in Burkina Faso.
Golden Rim reported that to date, 180 line km of the planned 500 line km survey (with 100m spaced lines) has been completed.
Initial data from the survey has outlined a strong, 1.6km long, IP chargeability-high anomaly at the Diabatou Prospect
Managing Director Craig Mackay said it is believed the IP anomaly is related to the pyrite mineralisation (up to 5%) that is associated with the high-grade gold mineralisation.
Previous drilling intersections within the IP anomaly at Diabatou include: 7m at 121.2g/t gold from 41m, including 1m at 783.8g/t gold; and 4m at 23.3g/t gold from 67m, including 1m at 65.7g/t gold.
The company recently commenced a 9,200m RC drilling and 4,000m diamond drilling programme (for a total of approximately 100 holes) at Kouri.
A diamond drilling rig is currently on the third hole at the Diabatou prospect which will test the new IP anomaly. It is located 60m along the interpreted southwest strike extent of the high grade gold mineralisation intersected in a previous RC drill hole (7m at 121.2g/t gold from 41m, including 1m at 783.8g/t gold from 44m, and 3m at 7.2g/t gold from 56m).
The first two diamond drill holes completed at Diabatou intersected multiple zones of granite- hosted quartz-pyrite mineralisation, with visible gold observed in one of the hoes.
Mr Mackay said a second rig (for RC drilling) will be utilised for the next few weeks to test the southern portion of the IP anomaly at Diabatou and then the northeast strike extent of the 1.4Moz Mineral Resource in the new Goueli Permit.
A major auger drilling programme comprising 3,750 holes (total of ~15,000m) is also underway. Drilling is initially being conducted at the Diabatou prospect and will then extend to systematically cover various target areas in the company’s newly acquired Margou Permit.
