Update on RC Drill Programme at Big One Deposit

Castillo Copper Limited (LSE and ASX: CCZ), a base metal explorer primarily focused on copper across Australia and Zambia, is pleased to provide an update on the Reverse Circulation ("RC") drilling campaign at the Big One Deposit, within the Company's 100% owned Mt Oxide Project in Western Australia, and to confirm strategic plans for the asset.

During Q4 2020, the drilling contractor completed 20 drill-holes at the Big One Deposit, comprising six drill-holes for the 200 series with partial assays for visible copper confirming up to 4.1% Cu and 14 drill-holes for the 300 series with visible copper mineralisation apparent in BO_301-06RC.

Highlights of H1 2021 priorities

· Subject to the receipt of final interpretations and full assays from the laboratory, the Board is targeting to release complete drill logs and relevant observations for all 20 drill-holes - in two to three batches - shortly

· With geological interpretations of historic and fresh assays suggesting a shallow, high-grade scalable copper system apparent at the Big One Deposit, the Board is prioritising the following for H1 2021:

o  Conduct a comprehensive geophysical campaign to identify potential massive sulphide conductors that would extend known mineralisation and provide new test-drill targets along the strike extent; 

o  Complete the current campaign as soon as practical then move onto the Arya Prospect; and

o  Commence work on modelling up a JORC compliant resource at the Big One Deposit then, subject to results of the modelling, apply for a new mining lease

· Overall, the Board is delighted with the progress of the drilling campaign to date and will keep shareholders informed of news as it materialises

Next steps

· Release drill logs and full assay results for all 20 drill-holes and detailed plans for the geophysical campaign

Simon Paull, Managing Director of Castillo Copper, commented: "Having completed 20 drill-holes of the current drilling campaign, the Board is delighted with the potential of the Big One Deposit. With geological interpretations of historic and fresh assays suggesting a shallow, high-grade scalable copper system apparent at the Big One Deposit, the Board is optimistic that 2021 will be a transformative year and that significant shareholder value can be created as the Mt Oxide Project is developed."

RC DRILLING CAMPAIGN - PROGRESS REPORT

During Q4 2020, the contractor completed 20 drill-holes at the Big One Deposit, comprising six from the 200 series and 14 from the 300 series. To date, partial assays for visible copper have been received for the 200 series, with up to 4.1% Cu confirmed. For the 300 series, visible copper mineralisation has been noted for six drill-holes - BO_301-06RC.

The full assay results for all 20 drill-holes, which includes interpretations and relevant observations, is expected back from the laboratory, in two to three batches, shortly.

Ramping up

With geological interpretations of current and historic data suggesting a shallow, high-grade scalable copper system apparent at the Big One Deposit, the Board has prioritised forward plans for H1 2021 which include:

· Undertaking a comprehensive geophysical survey to identify potential massive sulphide bedrock conductors that would extend known mineralisation and provide incremental test-drill targets along the strike extent

· Finish the current RC drilling campaign as soon as practical then move onto the Arya Prospect

· Start work on modelling up a JORC compliant resource at the Big One Deposit and then, subject to the results of modelling, apply for a fresh mining lease

About Castillo Copper

Castillo Copper Limited is an Australian-based explorer primarily focused on copper across Australia and Zambia. The Company is embarking on a strategic transformation to morph into a mid-tier copper group underpinned by its core projects:

· The Mt Oxide project in the Mt Isa copper-belt district, north-west Queensland, which delivers significant exploration upside through having several high-grade targets and a sizeable untested anomaly within its boundaries in a copper-rich region

· Four high-quality prospective assets across Zambia's copper-belt which is the second largest copper producer in Africa

· A large tenure footprint proximal to Broken Hill's world-class deposit that is prospective for zinc-silver-lead-copper-gold

· Cangai Copper Mine in northern New South Wales, which is one of Australia's highest grading historic copper mines

The Company is listed on the LSE and ASX under the ticker "CCZ".
