Select drill highlights are:
- DCH-041 intersected 0.75% copper over 17.80 meters, including 2.15% copper over 3.00 meters;
- DCH-046 intersected 0.83% copper over 16.30 meters, including 2.09% copper over 5.00 meters.
Drill holes DCH-041 through DCH-046 were drilled to test for mineralization below the central and northern portions of the Atajo Zone. All six of these holes intersected a broad zone of a coarse tectonic breccia that was locally cemented with copper oxide mineralization grading up to 6.31% copper over 1.0 meters. The zone has been intruded by late stage dikes which are barren of any mineralization. This style of mineralization is very similar to the Katty Zone, located 2 kilometers southeast of Adriana. Holes DCH-047 and DCH-050 tested the southern extension of Atajo and intersected the tectonic breccia but did not contain any significant copper values. Hole DCH-047 intersected a parallel zone with low grade values which had been located as part of the mapping program.
The drilling at Atajo has successfully outlined two mineral trends within the tectonic breccia that measures approximately 250 meters long, varies from 12 to 50 meters wide, and is open to the north and at depth. Future work contemplates the completion of an IP geophysical survey and additional drilling to further delineate the existing mineralization and potentially locate its source.
Elsewhere on the project, one drill has continued working at Adriana where it has completed one fan of step out drill holes to the southeast, and is in the process of completing a second fan of holes. The second drill was moved to the Vicky Zone, located 4 kilometers southeast of Adriana, where it has been drilling two regional holes testing several surface showings and their associated geophysical targets. Assays for this drilling will be released when available. To date, the Company has completed over 15,000 meters of diamond drilling at Chapitos since work began in May of this year.
Analytical procedures for soluble copper have been revised to now include a sequential leach first for oxide copper and then for secondary sulphide minerals such as chalcocite and bornite. Both oxide and secondary sulphide mineralization are potentially recoverable in a copper heap leach operation. The Company has completed reanalysis of a select amount of samples from earlier drilling. Where secondary sulphides were present, the amount of soluble copper increased substantially. Camino will re-analyze all of the mineralized intervals from holes DCH-001 through DCH-040 over the coming months and report the revised soluble copper values when the analysis has been completed.
Kenneth C. McNaughton, M.A.Sc., P.Eng., is the Qualified Person (QP) responsible for the Chapitos project.

(2)All samples were submitted for preparation and analysis by ALS Chemex at its facilities in Lima, Peru. All samples were analyzed using multi-digestion with ICP finish and select samples were analyzed for gold using fire assay with AA finish. Samples over 1% copper were reanalyzed using four acid digestion with an ore grade ICP finish. Mineralized samples were analyzed for soluble copper by a sequential leaching. The samples are first agitated at room temperature in a 5% sulphuric acid solution with the copper content measured by AA. The tails from the acid leach are then agitated in a 10% sodium cyanide solution with an AA finish to determine the amount of copper contained in secondary sulphides such as chalcocite and bornite. One in 20 samples was blank, one in 20 was a standard sample, and one in 20 samples had a sample cut from assay rejects assayed as a field duplicate at ALS Chemex in Lima, Peru.
