Further Exploration Defines Additional Gold-Silver Targets at Aurania's Lost Cities Project

Indication of Large Mineralized System

Toronto, Ontario, September 09, 2019 – Aurania Resources Ltd. (TSXV: ARU) (OTCQB: AUIAF) (Frankfurt: 20Q) (“Aurania” or the “Company” - https://www.commodity-tv.net/c/search_adv/?v=299154 ) reports that follow-up exploration is defining additional, extensive epithermal targets for gold and silver at the Tiria target area on the flanks of a 15 kilometre (“km”) trend of silver-zinc-lead mineralization at its Lost Cities – Cutucu Project (“Project”) in Ecuador.   The Tiria epithermal target was originally described as ‘Tiria East’ and ‘Tiria West’ (see press release dated November 29, 2018).  The Company has now identified four separate targets within the extensive Tiria target area.  These targets lie on the margins of a core of silver-zinc-lead, providing strong indications of a large mineralized system.

Aurania’s Chairman and CEO, Dr. Keith Barron, commented, “We continue to build our portfolio of epithermal targets, which currently sits at 20 targets, in our search for the next Fruta del Norte.  The way in which the Tiria targets for gold-silver are arranged around a corridor of silver-zinc-lead, suggests that we are looking at a large and coherent mineralized system.  We believe that the silver, zinc and lead accumulated in the hotter core in the centre of the system and that gold and silver precipitated at the cooler margins.  I’m impressed by the grades in the core target area and I believe that we are likely to be in a position to joint venture the silver-zinc-lead target shortly.”

Tiria Targets
Four separate target areas have been identified through the presence of blocks of various types of silica that exhibit characteristics of epithermal systems, such as chalcedony veins and hydrothermal breccia.  The Tiria targets have a combined length of approximately 20km and two of the targets are up to 3km wide (Figure 1).  Initial ridge-and-spur soil sampling has identified north- to northwest-trending areas of enrichment in pathfinder elements for epithermal systems, such as naturally occurring antimony and mercury.  Silver distribution in soil is an invaluable exploration tool in this area since it occurs in both the epithermal environment and the zinc-lead target.  These corridors of silver and pathfinder enrichment will be the focus of further exploration for epithermal gold-silver.   

Shimpia Target
High-grade silver (up to 325 grams per tonne (“g/t”)) with high-grade zinc and lead were reported in Aurania’s first press release on the Shimpia target on November 29, 2018.  Further exploration has encountered even higher grades, with up to 710g/t silver, 42% zinc and 9.2% lead in boulders in streams (Table 1).  A major step forward was the discovery of a 300m long area of breccia in carbonate host-rock – the highest-grade sample from which contains 356g/t silver, 12.7% zinc and 11% lead. The breccia contains abundant sphalerite (zinc sulphide) and galena (lead sulphide).  The silver is not identifiable as a separate mineral and is suspected to occur within galena. 

Regional Context
The current exploration concept is that the conspicuous magnetic zone at Jempe, interpreted as a buried porphyry with copper potential, is genetically related to the silver-zinc-lead zone at Shimpia, that then evolves outward and upward into the Tiria epithermal targets for gold and silver.  Magnetic data from the heliborne survey flown by Aurania shows that these targets are linked by faults that provided conduits along which the metal-bearing fluids first deposited copper, followed by silver-zinc-lead, finally emerging at surface to form the silica terraces that represent the four epithermal targets at Shimpia (Figure 2).

Next Steps
Further exploration will focus on the corridors of enrichment of pathfinder elements and silver in the epithermal target areas with the aim of advancing them toward scout drilling.  This work will include additional soil sampling, geological mapping and detailed alteration mineral analysis of soil and rock samples. Induced polarization geophysical surveys may also be considered as a means of imaging silica-rich features such as veins, as well as sulphide minerals at depth.  The silver-zinc-lead mineralization is not core to Aurania and is likely to be made available to interested parties for joint venture.
Update on Drilling at Yawi
The water-use permit has been obtained for the scout drilling at Yawi and final preparations are underway for the program which is expected to commence on the first of four targets later in September.

Sample Analysis & Quality Assurance / Quality Control (“QAQC”)
Laboratories: The samples were prepared for analysis at ALS Global’s (“ALS”) lab in Quito, or at MS Analytical (“MSA”) in Cuenca, Ecuador.  Analysis by ALS was done in Lima, Peru, and MSA conducted their analyses in Vancouver, Canada.
Sample preparation: Soil samples consisted of approximately one kilogram of clay from the iron-rich “B” horizon at each sample point. The soil samples were dried and subsequently screened through 80 mesh (using screens with apertures of approximately 0.18 millimetres).  A 250 gram (“g”) split of the material that passed through 80 mesh was pulverized to 85% passing 0.075mm and was packaged for shipment to the analytical facility. 
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 200g split was set aside for analysis. 
Analytical procedure:  A 0.5g split of the -0.075mm fraction of soil samples underwent digestion with aqua regia, and rock samples by four-acids, and the liquid was analyzed for 48 elements by ICP-MS. Samples that had lead and zinc grades of greater than 1%, and silver grades of over 100g/t underwent a second analysis in which 0.4 grams of pulp was digested in a mixture of four acids and the resulting liquid was diluted and analyzed by ICP-MS.  Apart from being analyzed by ICP-MS, gold was also analyzed by fire assay with an ICP-AES finish.   
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.
