Vancouver, November 23, 2022 – Camino Corp. (TSXV: COR) (OTC: CAMZF) (WKN: A116E1) (“Camino” or the “Company”) is pleased to announce high solubility results over significant copper oxide intercepts in the new Lourdes Zone at its Los Chapitos property in Peru. The near-surface copper oxide minerals in drillholes DCH-97 and DCH-80 had acid solubilities of 83% and 79%, and total solubilities of 92% and 87%, respectively. The solubility results confirm continuity of oxide mineralization to a depth of at least 100 metres in the new zone. Lourdes is one of several new zones identified to target additional drilling campaigns to expand known copper mineralization at Los Chapitos for an envisioned copper oxide heap-leach mine.

Results from the July 2022 drilling campaign can be viewed in Camino’s news release dated September 7, 2022.


• 83% acid solubility and 92% total solubility in drill hole DCH-97 that intercepted:
– 55.5m @ 0.93% Cu from surface, including 7.5m @ 2.58% Cu;
• 79% acid solubility and 87% total solubility in drill hole DCH-80 that intercepted:
– 65.2m @ 0.70% Cu from surface, including 31m @ 1.23% Cu;
• Hole DCH-83 in the Condori zone shows well-marked zonation of copper oxides, and mixed and enriched supergene (with anomalous values in rhenium and gold grading up to 0.21 ppm and 0.13 ppm, respectively).

“A copper oxide heap-leach mine is generally the easiest and most cost-effective method to start development of a copper project”, said Jay Chmelauskas, CEO of Camino. “As we permit new areas for drilling at Los Chapitos, we are finding more near-surface copper mineralization amenable to our development vision. At depth, we also see potential for large sulphide mineralized bodies as a second phase to our development strategy.”

“The solubility results confirm near-surface oxide mineralization to a depth of a least 100 metres at Lourdes, which compares favourably to oxide mineralization at our Adriana zone that extends to depths of over 200 metres”, said Jose Bassan, Chief Geologist. “The results of the geochemical analysis were consistent with mineralization described in drilling logs by Camino geologists (Figure 1). Our geological team will use this experience to continue exploring our Los Chapitos property for surface evidence along large structural faults that crosscut the property.”

D) DCH-83_90.80 m. Hydrothermal breccia (BXH) green copper oxides/pitch limonite in breccia matrix (0.64% Cu, Mixed Zone).
E) DCH-97 35m. Crystal Andesitic Tuff (CAT), mineralization corresponds to chrysocolla and tenorite in fractures and veinlets (0.8% Cu, Oxide Zone)
F) DCH-80_36.20m. Crystal Andesitic Tuff, mineralization is chrysocolla and black oxides in fractures and veinlets (1.61% Cu, Oxide Zone).

Metallurgical Heap-Leach Testing

The copper oxide mineralization with acid solubilities CuS (Sulfuric Leach)/CuT ratios up to 99% in the Lourdes zone shows good continuity to depths of at least 100 metres. In the new Condori zone, hole DCH-83 shows well marked zonation of copper oxides, with mixed and enriched supergene. Solubility results from the main Adriana Zone are summarized in the technical report titled “NI 43-101 Technical Report on the Los Chapitos Property, Arequipa Province, Peru” dated March 19, 2018 and available under the Company’s SEDAR profile at www.sedar.com. High solubility results reported in our new discovery at the Lourdes Zone are similar to the results at Adriana.
Metallurgical analyses developed at SGS Minerals S.A. Santiago for the Adriana drill holes in oxide composites to depths of approximately 300m, showed up to 74% average copper recoveries for composite head grade of 0.80% Cu from 3 Column tests, 73% to 76% copper recoveries from Bottle Roll tests with preliminary acid consumption rates for bottle/column of 3.3/9.05 kg acid/kg Cu. A summary of previous metallurgical column testing results for Los Chapitos can be found in Camino’s news release dated May 14, 2020.

Sequential Copper procedures

The Company analyzed 293 samples (429 metres) with 1.5 metre average intervals, for sequential copper from the 2022 Lourdes-Condori discoveries. 237 samples (345 metres) have geochemical analysis for copper >=0.1% Cu (48 element four acid ICP-MS). 72% of the samples had CuS/CuT ratio >= 55%. In the Lourdes Zone, continuity of oxidized mineralization extends to at least 100 metres from surface. The Condori Zone, located 1.5 km north of Lourdes, has mainly mixed mineralization in 56% of the intervals analyzed by sequential copper. Drill hole DCH-83, showed mixed mineralization composed of:

• pyrite, chalcopyrite, and chalcocite at depths of 6 to 89 metres;
• a zone of copper oxides at depths of 89 to 97 metres associated with crackle breccia grading up to 1.6% CuT;
• and at depths of 97 to 127 metres, a supergene enriched zone with values up to 0.77% CuT and anomalous values in rhenium grading up to 0.21 ppm, gold 0.13 ppm, Molybdenum 633 ppm and Cobalt 108 ppm.

Sequential copper analysis on the pulps samples from the drill core using the flying disc mill or the ring and disc mill (PUL-31- Pulverized split -250 g (85%<75 microns) was performed at ALS Perú S.A.. The geochemical analysis of the pulps consisted of Sulfuric Leach (Cu-AA06s) and Cyanide Leach (Cu-AA16s) with the Lab Instrument “AAS” (Atomic Absorption Spectroscopy) in acceptable ranges from 0.01 to 100% without residual value analysis. Copper oxide minerals such as malachite, azurite, chrysocolla and portions of cuprite and tenorite can be leached using sulphuric acid (referred to as ‘acid soluble’ copper). Cyanide leach will dissolve the secondary chalcocite, covellite, bornite and a portion of the chalcopyrite content of the sample.
