Aurania Confirms Extensive, High-Grade Copper-Silver at 'Tsenken B' Target in Ecuador
Toronto, Ontario, July 30, 2020 – Aurania Resources Ltd. (TSXV: ARU) (OTCQB: AUIAF) (Frankfurt: 20Q) (“Aurania” or the “Company” - https://www.commodity-tv.com/ondemand/companies/profil/aurania-resources-ltd/) is pleased to report on extensive, sedimentary-hosted high-grade copper-silver in the Tsenken B target area in its Lost Cities – Cutucu Project (“Project”) in southeastern Ecuador. A summary of targets in the Tsenken area and next steps is provided in Table 1.
Dr. Keith Barron, Chairman and CEO of Aurania commented, “We are very encouraged to see the copper-silver in the Tsenken area resolving into specific targets that we aim to drill-test as soon as possible. The light-weight drill rig, that has a maximum reach of 800 metres (2,600 feet) is in country and will be deployed to site in the coming weeks to start the drill program on Tsenken N2 and N3, before proceeding to the other priority targets.”
The results reported extend from the intensely mineralized fault breccia at Tsenken A northwards over 6 kilometres (“km”). The copper-silver is hosted by sedimentary layers that contain fossilized, carbonized plant fragments within an enclosing stack of red-coloured sandstone or red beds. Copper minerals include malachite, chrysocolla, tenorite and chalcocite. Samples from sporadic outcrops that stick up through the jungle floor are distinguished from boulders found in streams and on hillsides in Figure 1.

Characteristics of target
Copper-silver – bearing hydrothermal (diatreme?) breccia
Field mapping & set-up for scout drilling
Copper enrichment in soil over conspicuous magnetic feature evident in the geophysical data
Detailed mapping & scout drilling
Conspicuous magnetic feature evident in the geophysical data
Soil sampling underway
Fault-related breccia with high-grade copper-silver. Adjacent sedimentary-hosted copper-silver likely related to metal-bearing fluid that rose up the fault
Field mapping & set-up for scout drilling
Sedimentary-hosted copper-silver mineralization in outcrop & boulders in carbon-bearing layers
Field mapping & soil sampling to define drill targets
Tsenken magnetic centre
Possible porphyry or “intrusive-related” cluster
Wide-spaced soil sampling

Sample Analysis & Quality Assurance / Quality Control (“QAQC”)
Laboratories: The rock samples were prepared for analysis at MS Analytical (“MSA”) in Cuenca, Ecuador, and the analyses were done in Vancouver, Canada.
Sample preparation: The rock samples were jaw-crushed to 10 mesh (crushed material passes through a mesh with apertures of 2 millimetres (“mm”)), from which a one-kilogram sub-sample was taken. The sub-sample was crushed to a grain size of 0.075mm and a 200 gram (“g”) split was set aside for analysis.
Analytical procedure: Approximately 0.25g of rock pulp underwent four-acid digestion and analysis for 48 elements by ICP-MS. For the over-limit samples, those that had a grade of greater than 1% copper and 100g/t silver, 0.4 grams of pulp underwent digestion in four acids and the resulting liquid was diluted and analyzed by ICP-MS.
QAQC: Aurania personnel inserted a certified standard pulp sample, alternating with a field blank, at approximate 20 sample intervals in all sample batches. Aurania’s analysis of results from its independent QAQC samples showed the batches reported on above, lie within acceptable limits. In addition, the labs reported that the analyses had passed their internal QAQC tests.
