NickelSearch gears up for further drilling at Carlingup Project, WA

Western Australian explorer NickelSearch (ASX:NIS) is preparing to undertake further drilling at the Sexton and B1 prospects within the Carlingup Nickel Sulphide Project in Western Australia.

The company, in which Medallion Metals (ASX:MM8) holds a 15.1% interest, plans to complete a second diamond drillhole to a depth of 250m at Sexton. This hole is about 60m along strike from the first hole.

Additionally, NickelSearch plans to complete a third diamond hole at B1, where intercepts in May 2023 confirmed and extended the area of known historical nickel sulphide intercepts, with sulphide-bearing komatiites and cumulate ultramafics logged. Assays for these results are outstanding.

The company reports the first 2 diamond drillholes at Sexton intersected further visual sulphides in the deeper target area of the Lower Mineralised Horizon (LMH).

The diamond drilling program at Sexton is targeting 2 distinct bodies of mineralisation encountered in earlier drilling and correlated by downhole electromagnetic (DHEM) surveys. NickelSearch says the intent of this campaign is to test the potential for further nickel sulphide mineralisation within the Upper Mineralised Horizon (UMH).

Observations from the diamond drillhole underway confirm the overall plunge length of Sexton mineralisation to extend to 190m, and it remains open both up- and down-plunge. NickelSearch says these results are encouraging, as the company is close to starting the second diamond hole at Sexton, which will continue to test the extent of the strike.

Commenting on the drilling, NickelSearch Managing Director Nicole Duncan says: “Diamond drilling is ongoing at Sexton, one of our highly prospective targets at Carlingup.

This is the second intersection of visual nickel mineralisation for this diamond hole, which aims to confirm the presence of thicker sulphide mineralisation down-plunge at Sexton”

This is the second intersection of visual nickel mineralisation for this diamond hole, which aims to confirm the presence of thicker sulphide mineralisation down-plunge at Sexton, which we identified from our earlier RC drilling campaign.

This additional intersection confirms the presence of massive sulphide mineralisation at depth and gives us significant optimisation around our nickel sulphide exploration program. We eagerly look forward to assay results in the coming weeks.”

NickelSearch says prior work at Sexton included a maiden drill program of 4 reverse circulation (RC) holes that intersected nickel-bearing sulphide mineralisation. The company says these intersections were consistent with nearby historical drill intersections in hole RVD01015 with 2.2m @ 1.2% Ni and 0.17% Cu from 98.2m.

Results recorded in NickelSearch’s maiden drilling program at Sexton include hole 23NRC009 with 3m @ 1.11% Ni, 0.2% Cu, and 460 parts per million (ppm) Co from 39m; and 23NRC010 with 5m @ 0.43% Ni, 0.06% Cu, and 321ppm Co from 22m.

DHEM surveys conducted within holes 23NRC011 and 23NRC012 detected conductive sources that correlated with both the upper and lower mineralised horizons within those holes. 

Modelling of the LMH suggested a ‘much stronger’ anomaly, which the company says is consistent with massive sulphide mineralisation and suggests the conductor could extend at least 100m further down-plunge to the east-southeast from 23NRC012. The extent of this conductor model is likely constrained by the extent of the effectiveness of the DHEM survey.

NickelSearch is a dedicated Western Australian nickel sulphide explorer focused on its flagship Carlingup Nickel Sulphide Project. The company says Carlingup has an existing resource base totalling 155,000 tonnes of contained nickel.

The project is located within the same greenstone corridor as IGO’s (ASX:IGO) Forrestania nickel mining complex and adjacent to First Quantum Minerals’ (TSE:FM) Ravensthorpe Nickel Operation.
