Aiming To Extend Known Mineralisation And Determine Potential Scalability
Castillo Copper Limited(ASX:CCZ)has defined its final drill targets for drilling at the Arya prospect and Big One Deposit, within the Mt Oxide pillar in Queensland.
Managing Director, Simon Paull, said the geology team has designed comprehensive drilling campaigns for the Arya prospect1 and Big One Deposit.
“Behind the scenes our team is working at a frenetic pace to ensure all the logistics are in place, so that we can move ahead with the inaugural Mt Oxide pillar drilling campaign.
“For the Arya and Big One Deposit, our objective with the upcoming drilling campaign is to extend known mineralisation and determine potential scalability.
“As such, one of the key focuses is to test how far high- grade supergene ore extends from surface along the strike extent and if this transitions into underlying sulphides at depth.”
The overall objective of the drilling campaigns is to determine the scalability of the Arya prospect and Big One Deposit. In particular, this will focus on ascertaining how deep supergene ore mineralisation extends and if this transitions into underlying sulphides at depth.
The current plan – Phase I – will see the drilling campaign commencing at the Arya prospect, once a drilling contractor has been selected and logistics in place, as all regulatory approvals have been 100% secured.
The Arya prospect has an interpreted potential massive sulphide geophysical conductor ~130m thick, with dimensions ~1,500m by ~450m and ~426m depth below surface.
Phase II of the campaign will then move to the Big One Deposit, where the core objective is to build on the knowledge uncovered in the 1990s. To re-cap, in mid-January 2020, CCZ reported assay results from previously listed West Australian Metals.
WME completed a 27-hole (1,673m) RC drilling campaign which delivered excellent economic copper intercepts up to 28.4% Cu. Notably, the drilling intersected shallow high-grade supergene copper ore.
The Big One Deposit drilling campaign will contain a Reverse Circulation (RC) programme of 35 drill-holes, up to ~4,385m, focused on a strike length of ~580m by ~120m. The proposed total drill hole depths range from ~50m up to ~250m, which equates to vertical depth drilling targets between ~26m to ~190m below surface. Incrementally, a Diamond Drill programme of two drill-holes, up to ~160m, which will focus on shallow supergene mineralisation targets at vertical depths ranging from ~26 to ~52m.
