Marvel Gold has drilling underway to test major karst target at Lakanfla Gold Project in Mali

The Lakanfla Gold Project is in the Kenieba inlier of western Mali, adjacent to the northern section of the gold-rich Senegal Mali Shear Zone and southeast of the tier-1 Sadiola gold mine.

Extensive artisanal working to the northwest of Target Zone-1 at the Lakanfla project

Marvel Gold Ltd (ASX:MVL) has started a drilling campaign at Lakanfla Gold Project in western Mali aimed at proving the existence of a karst and identifying the potentially mineralised areas of the gravity lows.

The program of about 3,800 metres will be carried out using a multi-purpose reverse circulation (RC)/diamond drill rig, which has been mobilised to the project.

Artisanal workings

Lakanfla hosts a significant number of active and historic artisanal gold workings which are coincident with major geochemical and gravity anomalies.

There is evidence of ground collapse at surface, indicative of karst (or cave-like) voids at depth within carbonate rock units.

Subject to the results, it is likely that follow-up drill programs will then be required, using the information gathered in this first phase, to vector in on potentially economic concentrations of gold mineralisation.

“Excited” by exploration potential

Executive director Chris van Wijk said: “We are incredibly excited by the exploration potential at Lakanfla and look forward to our maiden drill program to test the karst theory.

“We have designed this program to confirm that dissolution processes have taken place and to maximise the chances of intersecting mineralisation around the 7-kilometre strike of the gravity lows surrounding the granite intrusion.

“Lakanfla’s proximity to Sadiola means that any discovery will be economically significant for Marvel shareholders.”

Review of historical data 

The company has undertaken a review of historical geophysical data including the results of gravity, magnetics and induced polarisation surveys.

These datasets have been reprocessed to further refine planned drill targets.

Best targets are interpreted to demonstrate:

  • Proof of karst development, such as gravity lows at or near to the granite-carbonate contact;
  • A thickened overburden evidenced in historical drilling, indicative of karst-collapse; and
  • Targets proximal to shear-zones which may have yielded primary gold and enhanced groundwater flow and subsequent supergene processes.

Marvel plans to use RC drilling to better handle the variable lithologies expected, including areas of loosely consolidated material and voids.

Looking ahead 

Additionally, the company believes the larger diameter should maximise the amount of sample collected.

First results from the drill program are expected towards the end of November and into December.
