THE DRILL SERGEANT: Emmerson Resources (ASX: ERM) declared the initial results from the first three diamond holes completed at the company’s 100 per cent-owned Mauretania project at Tennant Creek as, “exceptional”.
Emmerson Resources carried completed Drill hole MTDD003 that intersected 15 metres at 45.2 grams per tonne gold from 92m, including 4m at 158g/t gold.
The hole was ultimately abandoned in mineralisation due to ground conditions.
The company indicated it had identified visible gold in the lower section of a second hole, MTDD004, and visible supergene copper minerals malachite and azurite identified in the bottom section of the final hole, MTDD005.
Assay results from MTDD004 and MTDD005 plus the remaining lower section of MTDD003 expected later this month.
“This early assay result from our first diamond drill hole at Mauretania demonstrates the exceptionally high-grade nature of the mineralisation at shallow depths and given its association with hematite, provides exciting potential for discovering further similar mineralisation across the Tennant Creek Mineral Field,” Emmerson Resources managing director Rob Bills said in the company’s announcement to the Australian Securities Exchange.
“On a comparative basis, this early result from our 100 per cent-owned Mauretania project suggests the previous program of RC drilling underrepresented the gold grades.
“Furthermore, the indicative grades at Mauretania exceed those seen during similar stage drilling at our recently commissioned Edna Beryl gold mine, which has a mined head grade of approximately 30 grams per tonne gold.
“The diamond drilling at Mauretania is part of a two-stage exploration program with the next stage consisting of deployment of a Sub-Audio Magnetics geophysical survey to map out the strike extent of the mineralisation.
“We thank the Northern Territory Government for awarding collaboration funding to trialling this new technology and look forward to seeing the results.”
Emmerson indicated the trial SAM survey at Mauretania will commence in mid-June 2019, aimed at mapping the extent of the sheared ironstone that hosts the high-grade gold mineralisation.
SAM technology has been developed for simultaneously mapping of electrical and magnetic responses and is a high definition, ground-based technique that has applications to shear hosted gold and copper.
In addition to the Mauretania testing, Emmerson will also apply SAM to the Black Snake – Three Thirty area within the company’s Southern project area.
The results of the SAM survey and the remaining assays from the May 2019 drilling program will be used by Emmerson to plan the next phase of drilling at Mauretania.
