Sabre Resources Ltd (ASX: SBR) has received excellent results from the first 12 of 18 RC holes (2,382m) drilled at the Nepean South Nickel Project (E15/1702) located near Coolgardie in the highly prospective Eastern Goldfields of WA.
Sabre is earning an 80% interest in the Nepean South E15/1702 from Metals Australia Ltd.
The RC drilling tested the targeted ultramafic rocks that are interpreted to extend the entire 12km strike length of the Nepean South tenement on five broad-spaced sections. The Project is located immediately along strike to the south of the Nepean massive nickel sulphide mine that produced 1.1Mt at 3.0% Ni between 1970 and 1987.
The results received are from the first 12 RC holes which tested the southern three sections of previous shallow RAB drilling (Mincor Resources NL, 2007-2012) that produced high nickel with copper grades in weathered ultramafic rocks including 6m @ 1.84% Ni and 0.02% Cu from 18m in NRB0482.
On the southern section, 6,534,550mN, high nickel grades with elevated copper have been produced from saprolite across a 200m wide zone that overlies the ultramafic sequence and includes the following intersections from the eastern or footwall side of the zone:
– 8m @ 0.78% Ni, 0.015% Cu from 32m incl. 4m @ 1.12% Ni, 0.03% Cu in NSRC0002 High-grade results have also been produced from across the central ultramafic target on section 6,537,600mN including: – 8m @ 1.01% Ni, 0.02% Cu from 28m incl. 3m @ 1.26% Ni in NSRC0012
“We’re ticking all the boxes with our initial drilling and magnetics programs at Nepean South,” CEO, Jon Dugdale, said.
“High nickel grades have been produced from the saprolite zone above sulphide bearing Kambalda-style ultramafics in fresh bedrock.
“A detailed drone magnetics survey has defined three ultramafic channels that are highly- prospective for massive nickel sulphide deposits.
“Our next step is to track down nickel-sulphide accumulations with electromagnetics and further drilling that will target massive sulphide deposits similar to those mined at Nepean, located only 10km along strike to the north in the same geology.”
The new RC holes also tested fresh rock below the saprolite intersections, intersecting disseminated sulphides including pyrrhotite, chalcopyrite and potentially the nickel sulphide pentlandite across the ultramafic/footwall basalt contact in NSRC0002 and at end of hole in NSRC0004.
Results of up to 4m @ 0.20% Ni, 28.4% MgO at end of hole (134-138m) in NSRC0004 have confirmed that classic, Kambalda-style channelised ultramafics (komatiites) have been intersected. This has confirmed potential for Kambalda/Nepean style massive nickel sulphide accumulations at the base of the high-MgO komatiitic ultramafic in contact with the footwall basalt below.
In parallel with the RC drilling, a detailed drone magnetics survey was flown along the entire length of the Nepean South tenement. The drone magnetics imagery has defined three distinct magnetic bodies that, based on the high nickel and MgO results from the drilling to date, represent channelised ultramafics prospective for nickel sulphide accumulations.
