ASX ANNOUNCEMENT
8 July 2021
HIGHEST GRADE TARGET TO DATE GENERATED AT MARAO PROJECT
==> picture [460 x 10] intentionally omitted <==
Key Highlights
-
A new very high grade heavy mineral sands (HMS) target, Maduacua, with a surface footprint measuring 3.5 sq km of grade >5%THM (visually estimated) has been identified at the Marao Project in Mozambique.
-
Maduacua is the highest grade of 3 HMS targets generated at Marao to date.
-
Mineralisation at Maduacua is from surface and remains open to the north, northeast and at depth.
-
A higher grade core defined by 2 holes of >6%THM (vis est) is surrounded by 5 holes of 5-6% THM (vis est). Results from these holes:
-
21MUHA131 0 – 13.5m 13.5m @ 6.9% THM;
-
• 21MUHA126 0 – 13.5m 13.5m @ 6.7% THM; • 21MUHA124 0 – 13.5m 13.5m @ 5.4% THM;
-
21MUHA128 0 – 13.5m 13.5m @ 5.4% THM;
-
• 21MUHA132 0 – 13.5m 13.5m @ 5.4% THM; • 21MUHA127 0 – 13.5m 13.5m @ 5.3% THM; and • 21MUHA130 0 – 13.5m 13.5m @ 5.0% THM.
-
Mineral assemblage investigations will be conducted from Heavy Mineral Concentrate (HMC) generated during drilling to follow-up on encouraging initial results of 50.05% Valuable Heavy Mineral (VHM) content (Ilmenite, Altered Ilmenite, Rutile and Zircon) from Scanning Electron Microscopy (SEM, refer ASX Announcement 27 April 2021).

Auger drilling reconnaissance program at Marao is now 35% completed.
MRG Metals Limited (“ MRG ” or “ the Company ”) ( ASX Code: MRQ ) is pleased to supply an update to the market on the ongoing progress at the Company’s Marao (6842L) HMS licence (Figure 1) where a third high grade target has been identified. This update covers 53 reconnaissance grid (500m X 1000m spaced; Figure 2 and 3) hand auger holes for a total of 621.5m (21MUAC086 to ‘138; Table 1) and the discovery of MRGs third target, the Maduacua Target (Figures 3 and 4). MRG has now completed 138 of the planned 391 (35%) reconnaissance auger holes at Marao.

The previous two Marao market updates covered the initial 25 auger holes and the discovery of the Magonde Target (refer ASX Announcement 18 March 2021), followed by the next 60 holes and the discovery of the Mandende Target (refer ASX Announcement 18 June 2021; Figure 3). The Mandende Target remains open in the north. In this program, holes 21MUHA092, ‘093 and ‘094 drilled have demonstrated VIS EST grades of 3.2% THM, 3.7% THM and 3.6% THM respectively (Table 1), therefore increasing the area of the Mandende Target from >9 sq km to >11 sq km (Figure 3). Further smaller targets that will be followed up with additional drilling have also been generated, hole 21MUAC0121 for instance returned VIS EST 6.3% THM from surface to 13.5m and is still open at depth (Figure 4 and Table 1).
The new Maduacua Target displays the best VIS EST THM grades discovered at Marao to date. 12 auger holes have demonstrated VIS EST THM grades of >3% THM per hole, showing the excellent potential of this target to be the next very high grade deposit for MRG. Of these holes:
-
2 holes have VIS EST 4.0 – 4.9% THM;
-
5 holes have VIS EST 5.0 – 6.0% THM;
-
Hole 21MUHA126 with VIS EST 6.7% THM from surface to 13.5m; and
-
Hole 21MUHA131 with VIS EST 6.9% THM from surface to 13.5m.
Individual 1.5m interval VIS EST THM grades as high as 9% THM was intersected (Table 1, Figure 5). The Maduacua Target is still open towards the North (Figure 4) and has an area currently of >6 sq km. All the holes within the Maduacua Target were mineralised from surface and still in mineralisation at end of drilling depth, several holes had VIS EST THM grades of >5% at the end of drilling depth, with 4 holes (21MUAC126, ‘130, ‘131 and ‘132) in VIS EST >6% THM at the final drilling interval. The Maduacua target remains open at depth.
Auger drilling at Marao is continuing on the reconnaissance grid. Mineralogical studies are ongoing from composite HMC samples from the auger drilling, which is following up on very encouraging initial mineralogical investigations from grab samples at two road quarry sites (Figure 3) within the Marao licence. The investigation showed encouraging up to 50.05% VHM content (Ilmenite, Altered Ilmenite, Rutile and Zircon) results from Scanning Electron Microscopy (SEM, refer ASX Announcement 27 April 2021) 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 (refer ASX Announcement 22 April 2020).
MRG Metals Chairman, Mr Andrew Van Der Zwan said: “Marao continues to prove itself as a dynamic project for MRG with the latest results in from auger drilling reconnaissance program delivering our third very high grade target, Maduacua, which is now the highest grade target at Marao. Even with only the 3.5 sqkm surface footprint to date identified, at 13.5m depth there is potential for an at surface resource in excess of 75 MT – before we have done any further follow up. With previous assemblage analysis of VHM components greater than 50%, this is a potentially high value discovery. Our auger reconnaissance program is now 35% complete and we look forward to providing further updates as we progress.”
