ASX-listed mineral explorer Strickland Metals (ASX:STK) has intersected a ‘high-grade’ zinc feeder zone and massive sulphide mineralisation at its Iroquois Zinc-Lead Project in Western Australia.
The company reports 4 diamond drillholes completed for 885.6m at the Iroquois base metal discovery intersected multiple zinc-lead-silver intersections.
Hole IQDD003 returned 58m @ 4.3% Zn and 3.7g/t Ag from 173m, including 11.1m @ 6.7% Zn and 7.4g/t Ag from 176m and 4.3m @ 27% Zn, 0.1% Pb, and 19.9g/t Ag from 226.7m; and IQDD001 intersected 21.2m @ 1.5% Zn plus Pb from 166m, including 3.5m @ 4% Zn from 183m.
This drilling program was designed to test a structural corridor interpreted as a ‘high-grade’ feeder zone to the previously reported zinc-lead mineralisation in the Iroquois dolomite unit.
Strickland says holes IQDD001 and IQDD003 intersected ‘significant’ polymetallic base metal mineralisation within the granodiorite basement, directly underlying the dolomite unit. This mineralisation is characterised by a wide zone of steeply dipping, sulphide-dominant veining composed of sphalerite-galena-chalcopyrite ore assemblage.
The company reports the width and intensity of this mineralisation increased ‘significantly’ in IQDD003, where a zone of massive sulphides was intersected in addition to dense veining.
Strickland believes Iroquois is prospective for both skarn-type mineralisation proximal to the Iroquois Intrusive and carbonatite replacement deposit-style (CRD) mineralisation along the Iroquois feeder structure itself, based on recent drill results.
Commenting on the results, Strickland Metals Chief Executive Officer Andrew Bray says: “Our maiden diamond drilling program at Iroquois has yielded fantastic initial results, intersecting a very impressive 4.3m @ 27% Zn from 226.7m, within a broader zone of 58m @ 4.3% Zn from 173m.
The same feeder structure was also intersected about 300m to the southwest in IQDD001. The company believes this basement mineralisation represents part of the plumbing for a much larger mineralising system at Iroquois.

Both IQDD001 and IQDD003 show strong continuity of mineralisation, which significantly strengthens towards intrusion. This demonstrably opens up the 1.8km mapped trend for significant carbonate replacement style mineralisation, as well as skarn-type mineralisation closer to the intrusion. Both concepts are high-priority and very promising drill targets for future programs.
Planning is underway for a ground-based IP survey, which will assist the company to vector towards further high-grade polymetallic mineralisation. Additional planning has also begun for follow-up drill programs.”
Bray notes that only a small part of the core from hole IQDD004 was able to be processed due to numerous weather events making the project inaccessible in recent weeks.
The company will be attending Mines and Money Connect Melbourne on June 14-15.
Strickland Metals is an ASX-listed mineral exploration company with a portfolio of projects across Australia. These include the Yandal Gold, Iroquois, and Bryah Basin projects.
