Birimian Gold defines mineralised extensions to Massigui gold zones
THE DRILL SERGEANT: Birimian Gold (ASX: BGS) has reported final analytical results from Reverse Circulation (RC) and Aircore (AC) drilling programs recently undertaken at the company’s Massigui gold project in southern Mali.
Birimian said the latest results had confirmed presence of extensive shallow gold mineralisation at the Viper and Koting prospects while supporting potential to define shallow gold resources amenable to open pit mining within the project.
Gold intersections in follow up RC drilling at the Viper prospect include;
20 metres at 2.27 grams per tonne gold from 44m, including 11m at 3.4g/t gold;
18m at 1.45g/t gold from 30m; and
3m at 3.56g/t gold from 44m.
Birimian said the drilling at the Viper prospect confirmed the presence of a geologically continuous zone of gold mineralisation extending in excess of 1.2 kilometres of strike.
The prospect has also been shown to host a number of high-grade gold zones, which the company has taken to indicate potential for open pit mineable gold resources.
“The current phase of RC drilling focused on the northern portion of the Viper mineralised trend to increase drill density and confirm grade continuity on drill sections spaced at 50 metre intervals adjacent to the high-grade zones intersected in the company’s earlier 100 metre-spaced drilling,” Birimian Gold said in its ASX announcement.
“Analytical results from this drilling have identified significant down dip extensions to higher grade mineralisation and confirmed robust grades between previous drill sections.”
Further broad mineralised intersections were also encountered in RC drilling carried out at Koting, which Birimian has interpreted to indicate extensions to near surface higher grade zones.
RC drilling highlights include:
26m at 1.54g/t gold from 20m;
17m at 1.21g/t gold from 7m;
9m at 2.41g/t from 128m, within 23m at 1.44g/t gold; and
2m at 4.19g/t gold from 138m.
Birimian explained that limited previous drilling carried out at the Koting prospect had returned ore grade intersections over very broad widths, however, the scale and tenor of the mineralisation it has identified to date suggests scope exists to define new gold resources which may be amenable to open-pit mining at Koting.
“The combined program of RC and AC drilling recently completed was designed test the strike and depth extensions of mineralisation to further define mineralised orientations and ore controls in advance of an anticipated infill drilling program,” Birimian Gold said.
“Analytical results from the RC drilling component of the program have returned highly significant shallow intersections which provide substantial encouragement for delineating open pit mineable resources at this location.”
