ASX ANNOUNCEMENT
27 January 2021
NHACUTSE HIGH GRADE ZONE FURTHER DEFINED - ON TRACK TO DELIVER MRG’S STATED EXPLORATION GOAL
==> picture [461 x 11] intentionally omitted <==
Key Highlights
-
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
-
High grade drilling success was achieved from surface at 10 Infill aircore holes into the Nhacutse High Grade Zone - significant Total Heavy Mineral (THM) assay results included: (refer Table 1):
o 20CSAC611 0 - 42m 42m @ 5.40 % THM Including 0 - 36m 36m @ 5.99 % THM with highest individual 3m interval grade of 10.03% THM o 20CSAC609 0 - 42m 42m @ 5.08 % THM Including 0 - 39m 39m @ 5.39 % THM o 20CSAC594 0 - 30m 30m @ 5.58 % THM o 20CSAC595 0 - 30m 30m @ 5.82 % THM
-
The surface footprint of Nhacutse High Grade Zone is 8 km[2] , to a depth consistently over 30 metres and up to 42 metres, remaining open at depth
-
Confidence increased in the 3 internal very high grade zones - a combined surface footprint of over 2.5 km[2] , represents the potential to deliver over 100 Million Tonnes of heavy mineral sand (HMS) at over 6%THM .
MRG Metals Limited (“ MRG ” or “ the Company ”) (ASX Code: MRQ) is pleased to announce the assay results from its most recent aircore drilling at Nhacutse Prospect, located within the Company’s Corridor Portfolio in Mozambique. The program was carried out in late October /early November 2020 and 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. (Figures 1,2, 3, 4 and 5).
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 (Table 1).
MRG Metals Chairman, Mr Andrew Van Der Zwan said: “The results received from our latest drilling at the Nhacutse Project has continued to deliver excellent findings with consistent assays, averaging over 5% THM from surface to depths up to 42m that still remain open. This firmly puts Nhacutse on track to deliver our stated exploration goal of over 100 million tonnes of higher value HMS.
With a surface footprint of the high grade zone at Nhacutse currently standing at 8km[2] , our confidence is continuing to grow in the three very high grade zones which could potentially deliver the 100 million tons at a grade of over 6% THM”

Nhacutse High Grade Target Infill and Delineation Drilling
This 10 hole Infill/Delineation aircore drilling program at Nhacutse (refer ASX Announcements 22 October 2020, 7 January 2021) has returned more high grade THM results and continue to build the Company’s confidence in the Nhacutse High Grade HMS zone.
Of the 10 holes drilled (20CSAC593 to ‘598 and 20CSAC608 to ‘611) in this area, 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(Figures 3 and 4; Table 1), with a highest individual intersection grade of the drilling program of 10.03% THM over 3m from 3033m from the same drillhole (Figure 5); and 20CSAC595, with 30m @ 5.82% THM from surface.
7 out of the 10 of the holes were still in >3% THM grades at their final drill depths. On some of the holes, very high grades were still present in the final samples. 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.
Importantly, the drilling has also allowed growing confidence in 3 very high grade zones that are situated within the high grade footprint (Figures 3). 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.

Visual estimated THM grades vs assay results
A comparison of the reported visible (VIS) % THM grades from the 10 aircore drillholes in this program (refer ASX Announcement 11 November 2020) to the actual assay results on averages per drillholes basis from this announcement shows a good correlation, with on average an underestimation on the VIS vs actual assay results of 0.51% THM.
On individual drillholes 6 of the 10 drillholes have VIS estimates within 0.5% THM of the actual assay results, 3 of the 10 drillholes have VIS estimates within 0.5-1.0% THM of the actual assay results; with only 1 hole at a difference +1% THM, in this case the VIS grades underestimated the actual grades by 1.22% THM.
The estimations on higher grades of +4.5% THM are less accurate, with the higher differences nearly all falling in the higher grade range, evidenced by the highest grade sample (Figure 3) with a VIS est of 6.0% THM vs the analytical result of 10.03% THM. The correlation in this batch of results is good and supports the use of VIS estimated THM grades for reporting and planning.
