Vancouver, British Columbia--(Newsfile Corp. - September 18, 2018) - Revelo Resources Corp. (TSXV: RVL) ("Revelo" or the "Company") is pleased to report that Teck Resources Chile Limitada ("Teck"), a 100% subsidiary of Teck Resources Limited, has completed an initial drill test of Revelo's Cerro Buenos Aires property in northern Chile, designed to test for a possible porphyry copper system. Teck signed an Option Agreement over the project in May (see Revelo news release dated May 29, 2018).
The initial drill test by Teck comprised 3 reverse circulation drill holes (906 m total) that targeted a magnetic high anomaly in an area that is covered by approximately 70 m to 80 m of post-mineral pediment, located immediately east of extensive outcropping hydrothermal alteration on Cerro Buenos Aires Hill.
The Teck drilling cut argillic and phyllic alteration, the latter associated with anomalous copper, molybdenum or zinc geochemistry, possibly representing the upper portions of a porphyry copper system associated with the magnetic anomaly.
Cerro Buenos Aires Property and Drill Results Highlights:
- Widespread advanced argillic alteration extends over more than 5 Km north-south on the Cerro Buenos Aires hill located immediately to the west of the area drill tested by Teck, and is indicative of the upper portions of a porphyry copper and associated high-sulphidation precious and base metals system. The overall hydrothermal system is very large — at least 20 Km2, with further extensions to the north. A key N-S splay to a regional fault system (Dominador Fault) lies along the eastern margins of the property.
- The area drilled by Teck is at topographically lower elevations and coincides with a magnetic high feature.
- Hole PL-LP-01 (total 300 m) was drilled close to the centre of the magnetic feature, as apparent on an analytic signal transformation of the magnetic data (see attached map), and passed through almost 70 m of post-mineral gravels before cutting a volcanic sequence of dacites and andesites displaying argillic alteration to 210 m and phyllic (sericitic) alteration to the end of hole. The transition from argillic to phyllic alteration coincides with an elevation of copper and molybdenum values based on Niton XRF results.
-- Phyllic alteration is typically zoned above and to the margins of a hypogene porphyry copper centre. - Holes PL-LP-02 (300 m) and PL-LP-03 (306 m) were drilled on the northern and western flanks of the magnetic anomaly respectively, some 500 m north and 400 m northwest of PL-LP-01. Both holes passed through similar post-mineral gravel cover and a similar geological sequence and displayed the transition from argillic to phyllic alteration at approximately 150 m and 135 m respectively. Both holes show anomalous zinc values from Niton XRF as the transition to phyllic alteration occurs.
-- Zinc is typically zoned distally around porphyry copper centres. - Geochemical assays for all holes are pending.
- Previous drilling by Revelo in 2008 (PBA018, 019 & 020) located some 1.5 Km to the northeast of the Teck drilling, also revealed anomalous copper up to 153 ppm towards the bottom of the three holes, associated with argillic alteration. Hole PBA019 also cut a 2 m wide structure with highly anomalous silver (51.7 ppm), which like zinc, is typically zoned around the margins of porphyry copper centres.
Tim Beale, CEO and President of Revelo commented, "The initial drill test by Teck was undertaken as a proof of concept, and the results are encouraging for the presence of a potentially mineralised hypogene porphyry copper centre associated with the magnetic anomaly, at greater depths than those drilled to date. We await further studies and results from Teck, together with a decision as to possible next steps."
