Drilling at Rosewood returns best results to date with
1.6km extension of high-grade HM mineralisation
Highlights
• 73 Air Core (AC) holes were drilled at the Rosewood heavy mineral (HM) prospect in April. Results from
first 10 drill holes now received and include numerous intercepts at higher grades than those previously
encountered.
• New intersections include:
o 25RW002 - 26m @ 17.2% HM from 7m, incl. 6m @ 36.4% HM from 27m.
o 25RW003 - 32m @ 11.1% HM from 10m, incl. 3m @ 22.7% HM from 11m.
o 25RW004 - 15m @ 11.5% HM from 6m, incl. 5m @ 20.9% HM from 7m.
• These results extend mineralisation an additional 1.6 kilometres northwards. Mineralisation in the
Rosewood East area now extends at least 3.6 kilometres in a north-south direction.
• Mineralisation remains open to the north at Rosewood East with the northernmost hole in this area
intersecting strong HM mineralisation:
o 25RW010 - 8m @ 13.1% HM from 6m, incl. 4m @ 20.5% HM from 7m.
• Results support and upgrade previous drilling indicating widespread (>15km2), shallow, high-grade HM
mineralisation at Rosewood.
• Mineralogy results to date indicate the Rosewood HM prospect has a very high, on average >95%
Valuable Heavy Mineral content, composed primarily of high titanium dioxide (TiO2) minerals.
• Results from 63 remaining Phase 2 drill holes at Rosewood expected in approximately 3 weeks.
Petratherm CEO, Peter Reid, commented:
“Drilling to date continues to demonstrate the potential size and high-grade mineralisation of the Rosewood
prospect.
“Importantly, these results also confirm the high-grade continuity and thickness of the prospect over a very large
area including right up to the extent of current drilling. On this basis, we would anticipate future step out Phase
3 exploration drilling in the coming weeks will continue to identify additional high-grade mineralisation and
extend the potential size of the exciting Rosewood discovery.
“Bulk sample test work will shortly get underway to inform separation processing and will produce our initial HM
sample products. This will be a key m
