The targets at Yawi lie within an area measuring approximately 4 kilometres (“km”) by 4km in the southern part of the Project. A paved road provides access to within 1km of the first target area to be scout drilled, while the furthest target would require moving the man-portable rig up to 4km from the road.
Soil sampling has identified four targets that contain elevated levels of silver and other “pathfinders” – elements that typically occur in epithermal gold-silver systems. Metal and pathfinder elements are concentrated in elongate zones 1km – 2km long and 100 metres (“m”) – 200m wide (Figure 1) that contain banded chalcedonic quartz veinlets that represent the upper fringes of vein systems. Target A shows evidence of gold enrichment within its silver and pathfinder element footprint (Figure 2).
Fossil geyser system
Successful targeting depends on a clear understanding of which part of the epithermal system is exposed by today’s erosion level. Once the extent of erosion has been established, the gold-mineralized zone, which is usually confined to a specific elevation range beneath the position of the original land surface as it existed at the time of mineralization, can be targeted. At Yawi, blocks of sinter (Figure 3) – where the original epithermal system reached surface as geysers and silica terraces like those in Yellowstone National Park – show where the top of the system was at the time of mineralization. Our drilling will aim to intersect the vein system represented by the metal-enriched corridors at an elevation several hundred metres beneath the altitude of the sinters at Yawi.
Similarities to the Fruta del Norte epithermal system
One of the peculiarities of targets A and D at Yawi (Figure 2) is that the metal and pathfinder enrichment in soil lies at elevations above the sinter. However, this unusual situation was also evident at the Fruta del Norte deposit, currently being developed by Lundin Gold some 100km south of our Project in Ecuador. The discovery of the deposit was made through drilling a zone of pathfinder-enriched soil that proved to be 125m above the buried sinter. Gold-silver mineralization lies just beneath the sinter layer at Fruta del Norte.
Update on Drill Planning
Current indications are that all permissions are expected to be in place for drilling to commence on the first of the Yawi targets in September 2019.
Induced polarization (“IP”), a geophysical technique designed to identify possible areas of quartz veining (through resistivity responses) and/or the presence of sulphides (through conductivity responses) to a depth of several hundred metres below surface, may be undertaken concurrently with the drilling at Yawi.
Sample Analysis & Quality Assurance / Quality Control (“QAQC”)
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 either at ALS Global’s (“ALS”) lab in Quito, Ecuador or 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 Lima, Peru, in the case of ALS, and in Vancouver, Canada in the case of MSA. Both labs used similar assay procedures: 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.

Forward-looking statements may be identified by such terms as “believes”, “anticipates”, “expects”, “estimates”, “may”, “could”, “would”, “will”, or “plan”. Since forward-looking statements are based on assumptions and address future events and conditions, by their very nature they involve inherent risks and uncertainties. Although these statements are based on information currently available to Aurania, Aurania provides no assurance that actual results will meet management’s expectations. Risks, uncertainties and other factors involved with forward-looking information could cause actual events, results, performance, prospects and opportunities to differ materially from those expressed or implied by such forward-looking information. Forward looking information in this news release includes, but is not limited to, Aurania’s objectives, goals or future plans, statements, exploration results, potential mineralization, the corporation’s portfolio, treasury, management team and enhanced capital markets profile, the estimation of mineral resources, exploration and mine development plans, timing of the commencement of operations and estimates of market conditions. Factors that could cause actual results to differ materially from such forward-looking information include, but are not limited to, failure to identify mineral resources, failure to convert estimated mineral resources to reserves, the inability to complete a feasibility study which recommends a production decision, the preliminary nature of metallurgical test results, delays in obtaining or failures to obtain required governmental, regulatory, environmental or other project approvals, political risks, inability to fulfill the duty to accommodate indigenous peoples, uncertainties relating to the availability and costs of financing needed in the future, changes in equity markets, inflation, changes in exchange rates, fluctuations in commodity prices, delays in the development of projects, capital and operating costs varying significantly from estimates and the other risks involved in the mineral exploration and development industry, and those risks set out in Aurania’s public documents filed on SEDAR. Although Aurania believes that the assumptions and factors used in preparing the forward-looking information in this news release are reasonable, undue reliance should not be placed on such information, which only applies as of the date of this news release, and no assurance can be given that such events will occur in the disclosed time frames or at all.
