Mundoro Capital Inc. is pleased to report assay results from drilling on the Company’s 100% owned exploration licenses, Dubrava and Zeleznik which are located at the central and northern end of the Timok Magmatic Complex in northeastern Serbia. The two exploration licences are under the Option Agreement between Mundoro and Japan Oil, Gas and Metals National Corporation. announced March 7, 2016 and as a result this drilling program was fully funded by JOGMEC. Further to Mundoro’s press release of July 5th, 2016, the drilling program completed a total of 3000 meters over eight drill holes. Three holes were drilled at each of the East Zone and West Zone respectively in the Zeleznik license and two holes were drilled at the Dubrava license.
Teo Dechev, CEO and President of Mundoro commented, “We believe the drill results continue to demonstrate the potential for both mineralized copper-gold porphyries as well as massive-sulphide style mineralization at the West Zone and East Zone respectively. Multiple intercepts assayed over 0.30% Cu over tens of metres demonstrating the potential for a mineralized system. Mundoro’s technical team is incorporating the new data into our model of the systems and looking forward to developing the follow up drilling program for the spring of 2017.”
The 2016 drill program at Zeleznik comprised a total of six diamond drill holes, three at each of the East Zone and West Zone targets respectively.
East Zone Drilling
The three holes drilled at the East Zone targeted potential strike and depth extensions of copper-gold mineralization identified in previous drill campaigns. The true widths of the drill hole intercepts below cannot be determined from the information available at this stage.
Drillhole ZELDD08 was sighted on untested copper-gold soil anomaly and directed towards a low resistivity and moderate IP anomaly at 500m depth. The drill hole intersected mineralised andesite:
17.1 m @ 0.32 g/t Au; 0.15% Cu from 50 m to 67.1 m,
including 3 m @ 0.62 g/t Au from 54m to 57m and 4m @ 0.37% Cu from 61 m to 65 m.
The mineralised interval is related to a fault zone after which the drill hole did not intersect significant results.
Drillhole ZELDD11 located 230 m south of ZELDD08 intersected from 120 m to 122.2 m ; 2.2 m @ 0.62 g/t Au; 25.10 g/t Ag; 0.52% Pb; 10.70% Zn related to massive pyrite replacing limestone.
Drillhole ZELDD10 located 270 m north of ZELDD08 did not intersected significant mineralisation.
Summary East Zone Interpretation
The three drill holes drilled at the eastern target demonstrated that the limestone unit is thicker to the east and the best mineralised intersections remain within the upper 200 m. Controlling structures and the andesite/limestone contacts appear to dip to the west.
The East Zone remains open laterally to the north and south as well as to the west under a thinner limestone cap. The limited and widely spaced drilling to-date has furthered the understanding of the target and Mundoro will be performing a detailed interpretation of the drilling results to determine the lateral extent and directions of the various mineralized structures and contacts. The Company believes that this area merits a follow-up program of fence drilling across the entire system.
The three holes drilled at the West Zone targeted an area where previous drilling identified mineralized diorite porphyry dykes hosted in the basement gneiss unit. The aim of the drill program was to gain a better understanding of the dyke geometry, test response of geophysical anomalies, and test the potential for building significant volume of mineralized material.
Drillhole ZELDD07 was drilled 100m to east and between drill holes ZELDD01 and ZELDD03 aiming to test the continuation of the mineralisation intersected in ZELDDD01 and strong IP-Resistivity geophysical anomaly. The hole intersected a large interval of pyrite-chalcopyrite mineralisation from 0 to 193.1m hosted in gneissic wall rock cut by several diorite porphyry dikes. The interval contains:
193.1 m @ 0.18% Cu; 0.036 g/t Au,
including 16 m @ 0.30% Cu; 0.062 g/t Au from 152 m to 168 m and
including 15.2 m @ 0.27% Cu; 0.082 g/t Au from 210.6 m to 225.8 m.
Drillhole ZELDD09 was drilled to test a west dipping IP-Resistivity geophysical anomaly. The hole cut low grade pyrite -chalcopyrite mineralisation hosted in gneissic wall rock through its entire length of 368.9m grading 0.12% Cu and 0.020 g/t Au. A few intervals related to A and B type porphyry veinlets returned:
14m @ 0.20% Cu, 0.035 g/t Au from 32 m to 46 m;
3.3m @ 0.35% Cu, 0.046 g/t Au from 76.7 m to 80 m; and
5m @ 0.30% Cu, 0.050 g/t Au from 135 m to 140 m.
The drill hole did not intersect porphyry dikes but appears to have been drilled parallel to or near a porphyry dyke.
Drillhole ZELDD12 is located 230m north of ZELDD09 and was sighted on a resistivity high coinciding with strong IP geophysical anomalies. The hole intersected quartz-diorite porphyry which is a late mineral porphyry phase suggesting that a multiphase porphyry system exists at the Zeleznik west zone. No significant intersections were returned from this hole.
Summary West Zone Interpretation
This three hole drilling program supports the interpretation that there is a large volume of low grade halo of mineralisation hosted in gneisses with higher grades related to potassic altered diorite porphyry dikes containing stockwork veining with pyrite-chalcopyrite. The mineralisation remains open in all directions and requires further systematic drill testing based on interpretation of drilling results as well as regional and detailed structural analysis.
The Company believes that part of the focus of further exploration work on both target areas should be to locate and better define the higher grade bearing porphyry dikes which would upgrade the lower grade bulk material to potentially minable material.
The 2016 drill program at Dubrava comprised of two drill holes which targeted under cover IP geophysical anomalies assumed to be related to previously intersected mineralised “pebble dike” in drill hole BJ04 which returned encouraging results. The two dill holes could not explain the geophysical anomalies. Analysis of drill core suggests that the intersected structures and late mineral quartz porphyry are dipping to west-south-west almost in parallel the direction of the drill holes.
The Company will be conducting structural analysis over the central licenses which will be combined with detailed interpretation of all results obtained to date in order to prioritize the next phase of exploration.
