CASTILLO COPPER LIMITED
("Castillo" or the "Company")
Comprehensive geophysical campaign to commence across key Zambia projects
Castillo Copper Limited (LSE and ASX: CCZ), a base metal explorer primarily focused on copper across Australia and Zambia, is pleased to announce the appointment of Geophex Surveys ("GS"), an experienced geophysical consultancy firm, to undertake comprehensive Induced Polarisation ("IP") surveys across its 100% owned Luanshya and Mkushi Projects in Zambia.
Highlights
· Comprehensive IP survey to commence shortly across the key Luanshya and Mkushi Projects located in Zambia's copper-belt
· Given the scale of the campaign, it will take 6-8 weeks to complete and fully analyse the results - reconciling these findings with known anomalous areas at surface should identify priority targets to drill
· During 2020, wide-spread soil sampling programs were undertaken at the Luanshya and Mkushi Projects, which resulted in the following:
o A 6km strike event was delineated at the Luanshya Project, ~6-10km south of China Nonferrous Mining Corp's three operating mines, with combined 2012 JORC compliant Proven & Probable Reserves totalling 52.3mt @ 1.26% Cu
o Within the Mkushi Project are five anomalous areas with strike lengths ranging from 2-7km (~20.5km in total) that are on a high-grade shear zone which links to Shi Yan Group's operating Mushiwemba Copper Mine (5km north-west)
· Zambia-based, Geophex Surveys, has been appointed to carry out the IP surveys across the Luanshya and Mkushi Projects:
o GS has significant experience undertaking geophysical survey work on various copper-gold projects in Zambia and Democratic Republic of Congo, resulting in the successful delineation of ore zones and target identification
· With Castillo having secured ample funding following the recently completed capital raising, the Board is now focused on rapidly advancing the Mt Oxide and key Zambia Projects
Simon Paull, Managing Director of Castillo Copper, said: "Having already completed soil sampling campaigns that have delineated anomalous areas across the Luanshya and Mkushi Projects, undertaking comprehensive IP surveys will potentially facilitate identifying targets to test drill. Overall, the Board looks forward to receiving the geophysicists interpretations, as the Luanshya and Mkushi Projects deliver significant exploration potential."
GEOPHYSICAL CAMPAIGNS
To accelerate identifying targets that can be drill-tested within the Luanshya and Mkushi Projects, Castillo has appointed GS to conduct comprehensive IP surveys which will take 6-8 weeks to complete then fully analyse the readings. The results will be reconciled against known anomalous areas at surface, which should enable target areas to be identified.
During 2020, comprehensive soil sampling campaigns were undertaken across the Luanshya and Mkushi Projects, which mapped out highly prospective areas for copper mineralisation.
Luanshya Project
The Luanshya Project is 6-10km south of China Nonferrous Mining Corp's (CNMC) three operating mines, with combined JORC (2012) compliant Proven & Probable Reserves of 52.3mt @ 1.26% Cu. Further, across the region are four NW-SE trendlines, which are ~5-10km wide, that host numerous historic / current operating mines & deposits. Of these, two trendlines host CNMC's three mines, with one directly intersecting the middle of the Luanshya Project and is coincident with Lower Roan Formation.
Previous surface sampling defined a 6km strike event within the Luanshya Project that is highly prospective for copper mineralisation.
Mkushi Project
There are two parallel, NE-SW shear zones, 2-3km apart that originate in Shi Yan Group's (SYG) contiguous mining lease. The operating Mushiwemba Copper Mine is within the north shear zone and constrained within SYG's ground. However, the south shear zone, which comprises similar geological structures, trends into the Mkushi Project and is a clear target area.
In addition, the soil sampling campaign highlighted five, well-defined, anomalous areas with respective strike lengths ranging from 2-7km (20.5km in aggregate). Given these anomalous zones are proximal to the shear zone, they are likely part of the same over-riding system.
Next steps
Exploration work is now moving into top gear, with several events set to commence, including:
· Progress report on the Big One Deposit drilling campaign;
· Update on preliminary downhole geophysical work at Big One Deposit; and
· Update on geophysics overview on the Arya Project ahead of drilling getting underway.

About Castillo Copper
Castillo Copper Limited is an Australian-based explorer primarily focused on copper across Australia and Zambia. The group 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 group is listed on the LSE and ASX under the ticker "CCZ."
