Summary

  • MRG Metals Limited (ASX:MRQ) has identified a third high-grade target at Marao (6842L) HMS licence - the Maduacua Target, which displays the best visually estimated total heavy mineral (THM) grades discovered at Marao to date.
  • So far, the Company has completed 138 of the planned 391 (35%) reconnaissance auger holes at Marao.
  • Auger drilling at Marao continues on the reconnaissance grid, and mineralogical studies are ongoing from composite Heavy Mineral Concentrate (HMC) samples.

MRG Metals Limited (ASX:MRQ) is a significant heavy minerals sand (HMS) player with four high-calibre 100%-owned projects and another project under application in Mozambique. Located in the world-prolific HMS province, MRG’s Corridor Central and South Portfolio are developing well. The Marao project too has been making significant strides for the past few months.

The Marao (6842L) and Marruca (6846L) projects are contiguous and comprise 385km2 area. Last year, MRG doubled its Mozambique tenement size with the approval of these exploration licences.

After discovering the Magonde Target and the Mandende Target earlier this year, MRG has now discovered a third very high-grade HMS target at Marao-Maduacua. Maduacua is the highest grade of three HMS targets generated at Marao to date.

MRG’s recent milestone: Discovery of Maduacua

“Marao continues to prove itself as a dynamic project for MRG,” says Chairman Mr Andrew Van Der Zwan.

Maduacua is part of the latest results from the auger drilling reconnaissance program at Marao. The new very high-grade HMS target has a surface footprint measuring 3.5 sq km of grade >5%THM (visually estimated). Mineralisation at target is from the surface and remains open to the north, northeast and at depth.

In the latest auger drilling program at Marao, holes 21MUHA092, ‘093, and ‘094 drilled have demonstrated VIS EST grades of 3.2% THM, 3.7% THM and 3.6% THM, respectively. This has increased the area of the Mandende Target from >9 sq km to >11 sq km.

Twelve auger holes have demonstrated VIS EST THM grades of >3% THM per hole. These depict the excellent potential of Maduacua to be the next very high-grade deposit for MRG. Of these holes-

  • Two holes have VIS EST 4.0 – 4.9% THM
  • Five holes have VIS EST 5.0 – 6.0% THM
  • Hole 21MUHA126 with VIS EST 6.7% THM from surface to 13.5m
  • Hole 21MUHA131 with VIS EST 6.9% THM from surface to 13.5m.

Besides, individual 1.5m interval VIS EST THM grades as high as 9% THM was intersected. All the holes within the Maduacua Target were mineralised from the surface and still in mineralisation at the end of the drilling depth. Several holes had VIS EST THM grades of >5% at the end of drilling depth. 4 holes (21MUAC126, ‘130, ‘131 and ‘132) had VIS EST >6% THM at the final drilling interval.

“There is potential for an at surface resource in excess of 75 MT – before we have done any further follow up,” explains Mr Andrew Van Der Zwan. Notably, with previous assemblage analysis of VHM components greater than 50%, this is a potentially high-value discovery.

Other significant findings

Following suit of the previous two sets of results from Marao’s auger drilling program, the latest results from the auger drilling reconnaissance program have been equally impressive.

Key highlights of previous auger drilling programs-

The third set of results covers 53 reconnaissance grid (500m X 1000m spaced) hand auger holes for a total of 621.5m, besides the significant Maduacua target discovery.

A higher-grade core has been defined by two holes of >6%THM (VIS EST) and is surrounded by five holes of 5-6% THM (VIS EST). Results are demonstrated below-

What next?

MRG notified that other smaller targets to be followed up with additional drilling have also been generated. For instance, hole 21MUAC0121 returned VIS EST 6.3% THM from surface to 13.5m and is still open at depth.

Meanwhile, auger drilling at Marao is continuing on the reconnaissance grid. In addition, mineralogical studies are ongoing from composite HMC samples.

Initial mineralogical investigations were encouraging and showed up to 50.05% VHM content (Ilmenite, Altered Ilmenite, Rutile and Zircon) results from Scanning Electron Microscopy. A significant percentage of the HMC (up to 8.36%) is represented by Andalusite. The Zircon content of 3.12% is also relatively high compared to MRG’s Koko Massava deposit.

MRG has now completed 138 of the planned 391 (35%) reconnaissance auger holes at Marao. Further updates are likely to be equally exciting.
