New South Wales:Jackaderry North & South: prospective for copper-cobalt.Initial results for Jackaderry North are very encouraging asanomalous cobalt (max 430ppm) were found in zonestrending north-northwest. For Jackaderry South, desktopreview focused on the historic Cangai Copper Cobalt Mine,which has confirmed deposits of supergene ore with up to35% copper.

Peak Hill & Total Minerals: prospective for copper-cobalt-zinc.Located within a 20km radius of Broken Hill, NSW. Sufficientpreliminary data to prove up a JORC compliant resource forcobalt-zinc.

Queensland: Big Oxide North & Hill of Grace: prospectivefor copper-cobalt. Located in Mt Isa, northwest Queensland.Big Oxide Copper mine has demonstrated occurrences ofcopper-cobalt-zinc-lead-silver-manganese-uranium.

Chile assets: wholly-owned Chilean assets comprise of sixexploration concessions across a total area of 1,800 hectares(known as ‘Trueno’ concessions) - well known for high gradecopper-gold projects.

Castillo Copper Limited (ASX: CCZ) has assets in eastern Australia and Chile. The Australian assets, which wereacquired outright in mid-2017, comprise of six highly prospective copper-cobalt-zinc project areas in New South Wales(NSW) and Queensland (QLD): Jackaderry North and South projects (NSW), Peak Hill and Total Minerals projects(NSW) and Big Oxide North and Hill of Grace (QLD).

The company’s strategy is to expedite production andgenerate cash flow through using 3rd party processors withinrange of the project areas and selling end-product on theLondon Metal Exchange. CCZ is optimistic that three JORCcompliant inferred resources can be modelled relativelyquickly, based on analysing historical data and inauguraldrilling programs.

Copper: most preferred commodity, with 75% used for electrical applications (powercables, building wires) and 25% for non-electrical applications (building construction)2.China has the highest demand for copper, accounting for ~50% of global copperdemand4. As of June 2017, it was predicted that prices will hit US$6,200/ton4.

Cobalt: a key component in cathodes for some types of rechargeable lithium-ionbatteries1. Therefore, as the demand for electric vehicles, renewable energy storageand portable devices increases, so does the interest in cobalt1,3. Estimated that thereis ~124,000 tons of cobalt supplied each year3. Since December 2016, the price for aton of cobalt metal increased from US$31,500/ton to US$36,000/ton – predicted tocontinue to rise3.
