AZARGA METALS CORP. (TSX-V:AZR) reports that it has received assay results from the first six drill holes from the ongoing 6,000 meter drilling program on its Unkur Copper-Silver Project in Eastern Russia. These results indicate the possibility of expanding the mineralized envelope at Unkur at depth and along strike.
Dr. Alexander Yakubchuk, VP Exploration observed the core from these drill holes and said: “Drill-hole AM19-004 has discovered the widest intercept of mineralization to date at Unkur. The mineralization in this hole consists of chalcopyrite-bornite-chalcocite material with two subintervals of 15m with an average grade of 0.84% copper and 43.9g/t silver, and 32m with an average grade of 1.02% copper and 128.7g/t silver. These results are supported by similar mineralization with partially received assays for holes AM19-005 and AM19-006, together with the 2016 drilling results indicating the presence of higher than the average of the resource grade mineralization extending over 1,200m in length and 400m down dip in the northern part of the current resource envelope. This suggests that it may be possible to expand the mineralized envelope at this location. Furthermore, drill holes AM19-002 and AM19-003b intercepted copper-silver mineralization some 2km southeast from the current resource envelope indicating a strong possibility for its expansion to the southeast as well.”

Drill-holes AM19-004, 005, and 006 aimed to test a potential higher-grade extension to the north of the current Resource envelope as well as collecting material for PFS-level metallurgical test work (see Figure 1). Results from AM19-004 showed a wide interval of mineralization – 86 meters between 194 and 280 meters with an average grade of 0.60% copper and 56g/t silver. (Figure 2 and Table 1). The partial assay results received for drill holes AM19-005 and AM19-006 (Figure 3 and Table 1 showed similar copper and silver grades (Table 1) albeit over narrower intervals. Together with drill-hole AM19-004 and 2016 drill-holes AM001, AM003, AM004, AM017, and AM020 (see press release February 16, 2017), they outline a +0.5% Cu envelope, which is more than 1,200 meters long and some 400 meters deep. The envelope remains open to the north and the Company plans to drill test this area following the results of the recent ground magnetic survey (see press release October 17, 2019).

Drill-holes AM19-002 and AM19-003b intercepted copper-silver mineralization some 2 kilometers southeast from the current resource envelope (Figures 1, 4), with intercepts of 6 meters with an average grade of 0.94% copper and 23g/t silver and 8 meters with an average grade of 0.33% copper and 22g/t silver, respectively. In additional to indicating a possible southeastward extension of the original mineralization envelope, these results also indicate a substantial downdip increase in grade.

Notes to Table: There were no significant assay results from drill hole AM19-001 which was drilled to test an induced polarization geophysical anomaly in the central part above the current resource shell. Results from drill holes AM19-005 and AM19-006 are based on partial assay results – final assay results may change these figures. All assays presented are uncapped.
The Unkur diamond drilling program is progressing well with approximately 3,800 meters of the planned 6,000 meterage completed to date. At the present rate of progress, the drilling should be completed in late March to early April 2020, with assay results continuing to be published as received between now and May/June 2020.
