Aurania Reports on the Copper Potential of Geophysical Targets
Update on Drilling at Yawi Gold-Silver Target
Toronto, December 3, 2019 - Aurania Resources Ltd. (TSXV: ARU) (OTCQB: AUIAF) (FSE: 20Q) ("Aurania" or the "Company") reports that soil sampling shows strong enrichment of copper directly over the Tsenken N2 geophysical feature that was identified as a second-tier target in the airborne magnetic survey that the Company completed over its Lost Cities - Cutucu Project ("Project") in southeastern Ecuador.
Soil sampling revealed copper enrichment over an area 2,000 metres ("m") long by 300m wide. As shown in Figure 1, the copper-enriched area corresponds closely with a magnetic feature that has similar dimensions. Geological mapping has confirmed the geophysical feature is altered diorite porphyry.
Aurania's Chairman and CEO, Dr. Keith Barron, commented, "The superimposition of strong copper enrichment in the soil over the Tsenken N2 magnetic feature, along with alteration observed in sporadic outcrops, points toward this being a porphyry copper target. This finding is a major step forward for the Company because many tens of similar targets, which were also initially interpreted to be of secondary importance, are evident in the geophysical data from our property. These results strengthen our conviction that our Project not only has great potential for gold, but also has the potential to become a significant copper district."

Next Steps at Tsenken
A soil sampling program, like the one completed over Tsenken N2, is planned for the N1, N3 and N4 targets, to be followed by rock chip sampling and preparation for scout drilling. The extent and timing of drilling will depend on how many of the prospective geophysical targets demonstrate similar copper enrichment. If this program begins to indicate a "cluster" of targets, the program will be expanded to further investigate multiple other clusters on the property.
Technical Details on the Tsenken N2 Target
Whole rock analysis from the intrusive rocks in the Tsenken target indicate that they are dioritic in composition. They are porphyritic in texture and are intensely altered to a quartz-sericite-pyrite mineral assemblage. Tsenken N2 is therefore interpreted as a porphyry target for copper. Porphyritic stocks in the Tsenken N2 area intrude red-beds of the Mid-Jurassic Chapiza Formation.
Yawi Drilling Update
After completion of the second hole at the Yawi A target, the drill has been moved to the Yawi B target, where hole YW-003 is inclined to the south beneath an extensive area of sinter. Hole YW-003 has currently reached a depth of 65m. Holes YW-001 and YW-002, drilled on target Yawi A, were 533m and 559m long, respectively.
Sample Analysis & Quality Assurance / Quality Control ("QAQC")
Soil sampling at Tsenken N2 was at 50m intervals on lines spaced 100m apart. Approximately one kilogram of material was collected from the iron-rich "B" horizon of the soil profile at each sample point. The soil samples were prepared for analysis at MS Analytical ("MSA") in Cuenca, Ecuador. The preparation lab dried and subsequently screened each sample at 80 mesh (using screens with apertures of approximately 0.18 millimetres). A 250g split of the -80 mesh material was pulverized to 85% passing 0.075mm, and was packaged by the lab for analysis in Vancouver, Canada. The assay procedure is as follows: a 0.5g split of the -0.075mm fraction of the -80 mesh material underwent digestion with aqua regia and the liquid was analyzed for 48 elements by ICP-MS; Apart from being analyzed by ICP-MS, gold was also analyzed by fire assay with an ICP-AES finish.
Aurania personnel inserted a certified standard pulp sample, alternating with a field blank, at approximate 20 sample intervals in all sample batches.
The labs reported that the analyses had passed their internal QAQC tests. In addition, Aurania's analysis of results from its independent QAQC samples showed the batches reported on above, lie within acceptable limits.
