Sabre Resources Ltd (ASX: SBR) has detected a second strong surface EM anomaly two km to the southwest of the Discovery Zone resource at Sherlock Bay nickel sulphide project in Western Australia’s Pilbara region.
Significantly, the new anomaly, detected from a surface moving-loop EM survey, is projected to occur on the southern Sherlock Intrusive contact.
This new EM anomaly is similar in strength to the recently-detected strong EM conductor on the northern sherlock Intrusive contact, extending for one km at the western end of the Discovery Zone nickel sulphide Mineral Resource.
Intrusive-related magmatic sulphides have previously been intersected on both the northern and southern margins of the Sherlock Intrusive in diamond hole SBDD0024,5, confirming the prospectivity of both contact zones.
Both strong EM conductors represent untested new priority drilling targets for the discovery of further massive/matrix breccia sulphide mineralization.
“The detection of a second strong EM anomaly, this time on the southern contact of the Sherlock Intrusive two km southwest of Discovery Zone, has further enhanced potential for additional massive sulphides and an upgrade to what is already a substantial Mineral Resource at Sherlock Bay,” CEO, Jon Dugdale, said.
“This, combined with planned metallurgical studies and further engineering work, will allow the company to fast-track a pre-feasibility study into a major new nickel sulphide development project, taking advantage of forecast future nickel and copper supply deficits and potential price increases.”
In addition to the EM anomalies, Sherlock Bay’s prospectivity has also been enhanced by higher- grade nickel-copper-cobalt bearing sulphide results from diamond drillhole SBDD005, the final hole of the latest drilling campaign.
SBDD005was drilled as a 100m step-out hole below a previous Discovery Zone intersection in SBD072A of 24m @0.8% Ni, 0.13% Cu, 0.04% Co incl. 7m @1.02% Ni, 0.14% Cu, 0.04% Co1.
SBDD005 intersected a 12.2m semi-massive and stringer sulphide zone from 341.8m, including 10- 30% pyrrhotite (Po), chalcopyrite (Cpy) and the nickel sulphide pentlandite (Pn) across lobes of the Sherlock mafic/ultramafic Intrusive.
