MRG Metals Limited (ASX: MRQ) announced that highly encouraging results including 42m @ 5.40 % THM were received from the most recent aircore drilling at its Nhacutse Prospect located within the Company’s Corridor Portfolio in Mozambique.
The company said that the latest results from further Infill/Delineation Aircore Drilling puts Nhacutse on track to deliver MRG’s stated exploration goal of +100 MT of higher value per ton than the foundation Koko Massava Resource.
MRQ reported that high-grade drilling success was achieved from surface at 10 Infill aircore holes into the Nhacutse High Grade Zone. MRG Metals said that the surface footprint of Nhacutse High Grade Zone is 8 km2, to a depth consistently over 30 metres and up to 42 metres, remaining open at depth.
Significant Total Heavy Mineral (THM) assay results included 20CSAC611 0 – 42m 42m @ 5.40 % THM including 0 – 36m 36m @ 5.99 % THM with highest individual 3m interval grade of 10.03% THM; and 20CSAC595 0 – 30m 30m @ 5.82 % THM.
The company said that its confidence increased in the 3 internal very high-grade zones – a combined surface footprint of over 2.5 km2, represents the potential to deliver over 100 Million Tonnes of heavy mineral sand (HMS) at over 6% THM.
Drilling at Nhacutse prospect
The company had carried out a drilling program at the Nhacutse prospect in late October /early November 2020, which consisted of 10 aircore drillholes for 342m, generating 114 samples for laboratory analysis. The drilling focussed on infill and delineation of the Nhacutse High Grade mineralised footprint.
The company has now announced the assay results from its most recent aircore drilling.
MRQ said that the drilling program has further confirmed the very high grade Total Heavy Mineral (THM) values within the Nhacutse High Grade target, in addition to further defining the outline of this area.
The company said that 7 of the 10 holes delivered average grades over the length of the holes of >4% THM, with the best results in 20CSAC611, 42m @ 5.40% THM, including 36m @ 5.99% THM from surface, with a highest individual intersection grade of the drilling program of 10.03% THM over 3m from 30-33m from the same drillhole; and 20CSAC595, with 30m @ 5.82% THM from surface.
MRQ noted that in 20CSAC594 the grade was 9.23% THM from 27-30m; in 20CSAC595 the grade was 8.09% THM from 27-30m and in 20CSAC596 the grade was 7.23% THM from 27-30m, clearly indicating the high-grade zone remains open at depth.
Assay THM% results for 10 Hole Infill/Delineation Drilling at Nhacutse are as shown below.
Increasing confidence in 3 very high-grade zones
The company said that the drilling also allowed growing confidence in 3 very high-grade zones situated within the high-grade footprint. MRQ said that the 3 zones have a combined surface footprint of over 2.5 sq km, representing the potential to deliver in excess of 100 Million Tonnes of very high grade mineralised sand assaying over 6% THM.
On track to deliver exploration goal
The company said that the latest results from further Infill/Delineation Aircore Drilling puts Nhacutse on track to deliver MRG’s stated exploration goal of +100 MT of higher value per ton than the foundation Koko Massava Resource
The company said that further work will include heavy liquid separation analysis for quantitative THM% data. MRQ said that additional mineral assemblage and ilmenite mineral chemistry analyses will also be undertaken on suitable composite HM samples to determine valuable heavy mineral components. The company said that TiO2 and contaminant test work analyses will also be undertaken as the project advances.
