    Castillo Copper receives ‘high-grade’ cobalt-zinc results from pXRF retesting at The Sisters

    Castillo Copper (ASX: CCZ) has encountered ‘high-grade’ cobalt-zinc mineralisation following re-testing of diamond drill core from The Sisters prospect within its Broken Hill Project in New South Wales.

    The results were generated from re-testing using pXRF analysers, and returned readings up to 1,705ppm Co and 9.63% Zn. Other individual grades include:

    • Hole BHDD1: 1.8m @ 820ppm Co from 124.7m
    • Hole BHDD2: 1.5m @ 320ppm Co from 138.4m

    The company also notes that several wide pXRF intervals were delineated with ‘high-grade’ cobalt-zinc readings at the Reefs Tank and Tors Tank Prospects, which returned cobalt grades up to 1,600ppm. Other notable grades include:

    • Hole 1800E1180N: 7m @ 1,600ppm Co from 30m
    • Hole 3E51N: 15m @ 760ppm Co from 67m
    • Hole 2925E1240S: 10m @ 520ppm Co from surface
    • Hole TT05W10N: 5m @ 520ppm Co from 45m

    Addressing the results, Castillo Copper’s CEO Dr Dennis Jensen stated: “The preliminary results from analysing The Sisters Prospect’s diamond core has delivered Castillo Copper an excellent outcome.

    “We now have compelling evidence, subject to final assays, there is high-grade cobalt-zinc mineralisation apparent and a prime target for future test drilling”

    We now have compelling evidence, subject to final assays, there is high-grade cobalt-zinc mineralisation apparent and a prime target for future test drilling. Furthermore, the Board believes that, once all the assays are in from The Sisters Prospect, there will be sufficient data to potentially prove up a primary global cobalt mineral resource estimate that complies with the JORC 2012 Code.”

    Castillo reports that these results, as well as further results yet to be finalised, will provide sufficient data to potentially generate a primary JORC-compliant cobalt Mineral Resource Estimate.

    Furthermore, the company also reports that a primary 1,200m structure has been intercepted at The Sisters, and appears to host ‘high-grade’ cobalt-zinc mineralisation.

    The Broken Hill Project, located near its namesake town in western New South Wales, covers a total area of 801.3km2 across 4 tenements.

    With re-testing work finalised, Castillo reports that it will move forward with follow up drill testing at the newly-located primary cobalt-zinc target while they await further assay results.
