Follow-up Of New Targets Identified In Early 2021
Panthera Resources Plc (AIM: PAT) has commenced a follow-up 150 line kilometre Gradient Array Induced Polarisation (IP) survey at the Kalaka gold project in Mali.
This survey follows the successful initial 167 line kilometre IP survey in early 2021 in the south of the licence area.
The previous IP survey in early 2021 delineated several high order chargeability anomalies.
One of these, the K1A gold prospect, has been drilled by previous explorers and is coincident with disseminated sulphides that represent the alteration system associated with a large, low-grade gold deposit with drill intercepts including:
- 249.3m @ 0.54g/t Au from 52m (to end of hole) including 8m @ 3.17g/t Au from 107m;
- 191.8m @ 0.52g/t Au (to end of hole); and
- 176.4m @ 0.49g/t Au from 24m (to end of hole)
The chargeability highs are all considered to be excellent exploration targets.
Several of the IP anomalies have higher chargeability responses than those seen at the K1A prospect, suggesting a higher sulphide content and hence possibly more intense alteration.
One target in the far south is a high order and is close to a zone of extensive artisanal workings targeting the base of laterite.
It is interpreted that the workings are targeting slightly transported gold mineralisation shedding from mineralisation directly associated with the chargeability high.
Managing Director, Mark Bolton, said that while several direct drill targets have already been delineated, some of the high order anomalies remain open due to being proximal to the edge of the previous survey.
The current programme will cover the interpreted extensions of these zones. Subject to the onset of the wet season, this survey will be completed before defining drill targets that are planned to be drill tested immediately after the wet season later this year and will enable all targets to be ranked and the highest priority targets selected for drilling.
“The IP geophysical technique has worked exceptionally well as a direct targeting tool across our West Africa projects,” Mr Bolton said.
“The direct correlation of the large K1A gold mineralisation system with a well-defined IP chargeability high, and the delineation of several additional, discrete chargeability highs, some with associated artisanal workings, geochemical anomalies and previous broad spaced RAB drill intercepts, is very encouraging.
“While direct targets already exist, we have elected to extend the IP survey to close off several high order anomalies near the edge of the existing surveys, allowing for the best targets to be selected for drill testing later in the year. The survey is expected to take around six weeks to complete and results will be reported as soon as they are available.”
