MRG Metals reveals high quality results from Corridor Heavy Mineral Sands Project portfolio

The results indicate a higher unit value assemblage occurs in heavy mineral sand on the eastern side of the Corridor tenements.

MRG Metals Ltd (ASX:MRQ) has revealed high quality mineral assemblage results from 16 composite samples within its Corridor Heavy Minerals Sand Projects in Mozambique.

Key results include:

  • Up to 68.29% combined Ilmenite / leucoxene, 2.17% rutile, and 2.91% zircon at the Nhacutse target;
  • 50.45% combined Ilmenite / leucoxene, 0.84% rutile, and 1.93% zircon at the Koko Massava East target; and
  • 46.50% combined Ilmenite / leucoxene, 0.75% rutile, and 1.78% zircon at Poiombo.

The composite samples were determined by Qemscan analysis, an integrated system comprising a scanning electron microscope and energy dispersing spectrometer plus proprietary software for data collection which is routinely used for determination of bulk mineral assemblage for heavy mineral sand samples.

“Highly prospective heavy minerals targets”

MRG Metals chairman Andrew Van Der Zwan said: “We continue to rapidly expand our knowledge and understanding of our massively endowed Corridor Sands Projects portfolio, which contains multiple highly prospective heavy minerals targets.

“Having returned our Maiden Mineral Resource Estimate of over 1.4 billion tonnes at 5.2% total heavy metal (THM) at Koko Massava back in April, we have turned our exploration efforts to assessing the exploration portfolio of surrounding targets with the aim of discovering even higher value per ton resources for optimization of a potential mine start-up.

“The significance of these latest results is staggering as the in-ground value of the best quality assemblage results reported is approaching double that of the Koko Massava combined sample at similar THM grade.

“Whilst we had previously stated that we are looking for grades of 7-8% THM as early mine life feedstock, if sand of the quality reported here from Nhacutse is found in quantity, the potential exists for this percentage to be lowered significantly.”

Given the significance of the Nhacutse result, MRG has retested the sample, with a further retest on a new split of the sample to be analysed shortly.

Ongoing analysis

A further batch of 16 composite samples for mineral assemblage characterisation obtained from the reconnaissance auger drilling, has been prepared and will also be analysed by Qemscan at CSIRO in the first half of August.

These samples are related to Zulene, Saia and Viaria targets on the Corridor South (6621L) tenement.

Samples will also be selected from very high-grade intersections in aircore drillholes completed at Poiombo target in March 2020 to determine relative assemblage value there.

Next steps

The new mineral assemblage results demonstrate a better value assemblage occurring to the eastern side of the tenements, further from the Limpopo River valley and significantly better than that reported for the Koko Massava Mineral Resource.

This important observation will be used as another prioritisation parameter in exploration targeting going forward and will be used to drive the selection of additional mineral assemblage samples.

MRG intends to use the data to develop priority targets for its upcoming aircore drill program.
