THE DRILL SERGEANT: Cassini Resources (ASX: CZI) is making progress on a regional exploration program underway at the West Musgrave Project (WMP) in Western Australia.
Cassini Resources is managing the exploration strategy program, which is funded as part of the Earn-in/JV Agreement the company has with OZ Minerals (ASX: OZL).
Under the Agreement, $4 million has been allocated for regional exploration during the current stage, which includes an ongoing Pre-Feasibility Study (PGS), with a further $4 million available during the next stage of the JV should OZ Minerals progress.
“The regional exploration strategy, managed by Cassini, is designed to identify additional high-value ore outside the Nebo-Babel deposits to complement the proposed mining operation,” Cassini Resources said in its ASX announcement.
“To achieve this, the company has identified a number of priority targets with the potential for providing high-grade nickel and/or copper mineralisation.
“The immediate priorities for 2018 program will be to follow-up the One Tree Hill discovery made in 2017, the Yappsu prospect, and further drilling at the Succoth copper deposit.”
Cassini has had Moving Loop Electromagnetic (MLEM) and Fixed Loop Electromagnetic (FLEM) surveys carried out to assist with drill targeting at the One Tree Hill and Yappsu prospects.
The new survey improved the MLEM response over the known mineralisation at Yappsu demonstrating a strong, discrete, late-time anomaly with a NW-SE trend yet the DHEM models could not fully explain the observed MLEM response.
“The new MLEM survey has provided additional confidence to drill targeting,” Cassini said.
“The primary target remains the confluence of DHEM plates from previous drilling.
“It is noted that the previous drilling has not tested the core of these conductors, yet holes have still returned significant mineralisation.
“The implication is that the core zones of the plates, all of which exhibit high modelled conductance, may consist of thicker and/or higher grade massive/matrix sulphide mineralisation.
“Drilling to test these conductors is now underway.”
At One Tree Hill, the MLEM survey defined a late-time conductive trend considered to be consistent with the position and depth of the known massive sulphides at the deposit.
The data has been interpreted to suggest that the small massive sulphide body defined by DHEM surveying was resolved from the surface, providing the company with confidence in other anomalies identified by the survey.
“The MLEM data suggests that the known massive sulphide mineralisation could extend as a narrow (less than 30m) zone over a strike extent of more than 700 metres in a NW-SE trend, perpendicular to general stratigraphy,” Cassini continued.
“There are a number of other interesting features in the survey, particularly a synclinal feature in the NE of the survey area.
“Conductors in this area are currently poorly constrained and require further evaluation.”
