Mincor Resources NL (ASX: MCR) has drilled two significant new high-grade massive sulphide nickel intersections, significantly extending the recently discovered mineralisation at the emerging “Hartley” prospect, 17km north-west of its Cassini mine.
Two new holes (MDD373W1 and MDD373W2) were drilled further south along strike from the high-grade intercepts announced in late August 2021, all within a three km long untested zone. The holes returned the following assay results:
- MDD373W1 – 1.4m @ 3.0 % Ni (on contact); and
- MDD373W2 – 4.5m @ 3.3 % Ni (including 0.6m @ 6.9% Ni, on contact)
The two holes were designed to test a 100m section to the south of the intercept in MDD372 (1.2m @ 3.5% Ni) reported in August. MDD373W2 is the most significant intersection encountered to date at the Hartley prospect in terms of its width, high grade and tenor.
Importantly, this intersection (4.5m @ 3.3% Ni) sits in an open contact position, with a secondary hanging wall intersection of 2.2m @ 2.4% Ni approximately six metres above the mineralisation on the basalt contact.
Interestingly, the contact was further to the east than modelled, suggesting a potentially more deeply embayed trough. These factors suggest that the mineralised channel could be stronger towards the south, although this will require further drilling to evaluate.
Managing Director, David Southam, said the next hole, MDD374, is currently underway testing a further 100 metres to the south along the plunge of the channel.
“These latest intercepts provide strong evidence that we have an exciting emerging exploration opportunity at the Hartley prospect, just 17km from our new Cassini mine,” Mr Southam said.
“We have now intersected high-grade nickel sulphides, with width, over a 200m strike length and while, we are still at a relatively early stage in terms of our understanding of the primary architecture and geometry, the high- quality results bode extremely well for the future prospectivity of this area.
“We are also very pleased to recognise our General Manager of Exploration, Rob Hartley, by upgrading the naming convention for this emerging area.
“This particular exploration program was generated by Rob and his team and it’s fitting to be able to acknowledge his substantial contribution to Mincor over a period of more than two decades. Rob was also part of the team recognised with last year’s AMEC Prospector of the Year Award for the Cassini.”
