ASX ANNOUNCEMENT
21 July 2022
MARAO DELIVERS HIGH LABORATORY GRADES FROM AIRCORE DRILLING –
MAGONDE ESTABLISHED AS VERY HIGH GRADE TARGET
Key Highlights
• Aircore drilling of 3 Heavy Mineral Sands (HMS) Targets at Marao (6842L) delivered high grade analytical results (refer Table 1):
o 22MUAC003 Magonde 0 – 27.0m 27.0m @ 6.04 % THM,
Including 16.5 – 25.5m 9.0m @ 9.93 % THM, (highest individual 1.5m interval grade of 13.49% THM);
o 22MUAC008 Mandende 0 – 42.0m 45.0m @ 3.65 % THM,
Including 33.0 – 40.5m 7.5m @ 7.12 % THM, (highest individual 1.5m interval grade of 10.63% THM);
o 22MUAC001 Magonde 0 – 37.5m 37.5m @ 3.04 % THM;
o 22MUAC006 Maduacua 0 – 45.0m 45.0m @ 3.37 % THM; and
o 22MUAC007 Maduacua 0 – 28.5m 28.5m @ 3.07 % THM.
• Magonde has already delivered significant mineral assemblage results of 50.05% Valuable Heavy Mineral (VHM) content (Ilmenite, Altered Ilmenite, Rutile and Zircon) by Scanning Electron Microscopy (SEM, refer ASX Announcement 27 April 2021).
• Significant outcomes of this target testing include:
o HMS grades of >3 % THM results were delivered from aircore holes in all 3 targets (Figures 2 and 3), confirming again the effectiveness of MRG’s auger drilling exploration technique;
o Magonde is now established as a very high grade (>6 % THM) target from results of 22MUAC003 (Figure 4);
o Decent grades of >3 % THM mineralisation confirmed from surface up to 45m depth;
o Very high grades of >10 % THM over 1.5m intersections confirmed in the Magonde and Mandende targets.
• Mineral assemblage investigation is currently underway for 14 composite samples taken from representative lithologies of the 3 targets.
• Marao has the potential to deliver HMS Mineral Resources of equivalent THM grade and higher VHM % than Koko Massava, Nhacutse and Poiombo deposits.
