Aurania Finds First Evidence of Porphyry-style Alteration Related to a Geophysical Target in it’s Lost Cities – Cutucu Project, Ecuador
Toronto, Ontario, March 15, 2018 – Aurania Resources Ltd. (TSX-V: ARU) (“Aurania” or the “Company”) is pleased to report that field work confirms that the Awacha geophysical Target Cluster also has geological and geochemical features that are typical of porphyry systems. This finding is significant because it supports the contention that Aurania’s project area likely contains porphyry deposits similar to the copper and copper-gold deposits of the adjacent Cordillera del Condor.
Aurania’s President, Dr. Richard Spencer commented,
“We are using the same stream sediment sampling technique in our Lost Cities – Cutucu Project (the “Project”) that was instrumental in the mid-1990’s discovery of large porphyry copper and copper-gold deposits located just a few tens of kilometres south of our property boundary. Aurania’s airborne magnetometer survey detected a cluster of magnetic features that we believe are the buried magnetic cores of porphyries, and our exploration team recently discovered surface rock exposures of quartz-sericite-pyrite (“QSP”) which represents an alteration shell that would typically enclose porphyry-style mineralization. This type of alteration further suggests that the target lies at a reasonably shallow depth. Since numerous similar magnetic features have been identified by the geophysical survey elsewhere across the Project, we are now more confident of the potential for these to be due to porphyry bodies as well”.
Awacha Target
The Awacha Target Cluster has been extended to include 13 magnetic centres, three more than were described in Aurania’s press release dated December 6, 2017 (https://aurania.com/aurania-reports-first-target-defined-geophysics-program-lost-cities-cutucu-project-ecuador/). Each centre is similar in size and intensity to magnetic features related to drilled and confirmed porphyry deposits along the geological trend, in the adjacent Cordillera del Condor. The closest porphyry that has a NI 43-101 copper resource is the Warintza Deposit, located 25 kilometres from the southwestern corner of the Project. The Warintza and Panantza copper deposits are the northernmost in a 150km-long chain of porphyry deposits that hosts more than 34 billion pounds of copper.
Initial stream sediment sampling over part of the Awacha cluster of magnetic targets identified molybdenum enrichment over the Awacha A Target and molybdenum, arsenic and slight copper enrichment over the Awacha B geophysical feature. Molybdenum is a key pathfinder element for porphyry deposits and arsenic typically occurs in the upper part of porphyry systems in association with quartz-sericite-pyrite alteration. Copper and gold typically are concentrated in the magnetic core that lies beneath the quartz-sericite-pyrite alteration zone.
Next Steps
With Awacha having provided the first confirmation of porphyry-style alteration over a magnetic feature, field teams are now working on other conspicuous geophysical features in the Project area. The field teams are sampling silt in streams in these target areas, while a second group of geologists is mapping geology and alteration patterns to confirm and refine these target areas for more intense rock-chip and soil sampling. The objective is to work up targets for scout drilling later this year. Our expectation is that the first phase of scout drilling will be done on epithermal gold-silver targets, such as the Latorre Target described in prior press releases (eg. February 28, 2018 https://aurania.com/aurania-expands-footprint-latorre-epithermal-target-lost-cities-cutucu-project-ecuador/), and some on porphyry copper and copper-gold targets.
