2016-04-14 08:21 ET - News Release ----- Mr. John Burzynski reports
OBAN INTERSECTS 24.7 G/T AU OVER 6.8 METRES AT WINDFALL
Oban Mining Corp. has released new results from the continuing drill program at its 100-per-cent-owned Windfall Lake gold project located in Urban Barry township, Quebec. The 55,000 metre drill program combines definition drilling above the Red Dog intrusion ("Red Dog") and expansion drilling above and below Red Dog.
Highlights from 9 new drill holes include: 24.7 g/t Au over 6.8 metres in the extension of DDH EAG-11-254; 5.21 g/t Au over 11.2 metres in DDH OBM-16-609; 18.9 g/t Au over 2.4 metres in DDH OBM-16-616; 6.94 g/t Au over 5.7 metres in DDH OBM-16-617; and 11.2 g/t Au over 3.4 metres in DDH OBM-16-614. The new results continue to demonstrate the lateral and vertical continuity of high grade gold mineralization in Zone 27 and highlights additional new gold mineralization below Red Dog. The table below outlines significant new results(1)(2):

Notes:
(1) For complete drilling results please see http://www.obanmining.com/.
(2) True widths are estimated at 65-80% of the reported core length
interval. See "Quality Control" below.
(3) High grade values cut to 100 g/t Au.
EAG-11-254 extension (section 2500) tested the FW3 Zone below Red Dog at 570 metres depth. The hole intersected 24.7 g/t Au over 6.8 metres from 684.1 to 690.9 metres in a sericitized and strongly silicified andesite with 5-30% pyrite in stockwork at the contact with a porphyry dyke. This intersection is located 63 metres up-plunge from previously reported DDH EAG-11-289 which returned 9.96 g/t Au over 5.8 metres. This new intersection expands the FW-3 Zone immediately below Red Dog.
OBM-16-605 (section 2575) was designed to infill the Caribou Zone and Zone 27. Both zones were intersected and consist of moderate to strong silica alteration with minor pyrite and returned anomalous gold values. Another interval of 3.64 g/t Au over 2.0 metres was intersected 12 metres away in the hanging wall of Zone 27.
OBM-16-607 returned no significant alteration or gold values.
OBM-16-609 (section 2550) tested the Caribou Zone and the Zone 27. The interval returned 5.21 g/t Au over 11.2 metres at 320 metres depth in an altered and mineralized porphyry dyke at the contact with an altered mafic volcanic rock unit.
OBM-16-611 (section 2250) tested Zone 27 30 metres east of previously reported hole OBM-16-608 which intersected 10.3 g/t Au over 9.3 metres. The new hole intersected 3.44 g/t Au over 4.4 metres in a deformed pyrite stockwork containing 5-10% pyrite hosted in an altered felsic and mafic volcanic flows. The hole also intersected 4.44 g/t Au over 4.5 metres in the hanging wall of Zone 27.
OBM-16-612 (section 2775) was abandoned and restarted as OBM-16-614.
OBM-16-613 (section 2550) is an infill hole which intersected two separate gold-bearing intervals in the Caribou Zone: 4.83 g/t Au over 2.2 metres and 4.43 g/t Au over 2.2 metres at 151 metres down the hole. The two intercepts are located above previously reported hole EAG-13-526 which returned 5.46 g/t gold over 3.0 metres, confirming continuity of gold mineralization.
OBM-16-614 (section 2775) targeted the FW3 Zone below Red Dog. The hole intersected new mineralization at 820 metres which returned 11.22 g/t Au over 3.4 metres. This intercept represents the southernmost zone drilled so far below Red Dog and indicates the potential for further new discovery below the intrusion. The hole was stopped before reaching the FW3 Zone due to technical difficulties and was wedged as OBM-16-614 W1 (results pending).
OBM-16-615 (section 2200) tested shallow mineralization in Zone 27 and returned 4.35 g/t Au over 2.5 metres in a weakly silicified rhyolite containing 2-3% pyrite stringers.
OBM-16-616 (section 1675) targeted the shallow southwest extension of the FW3 Zone below Red Dog. The interval returned 18.9 g/t Au over 2.4 metres in a strongly silicified rhyolite containing 20% pyrite stringers with 7% sphalerite and traces of galena.
OBM-16-617 (section 2150) was designed to test the upper portion of the Zone 27 at 50 metres to the southwest of OBM-16-615. The Zone interval returned 6.94 g/t Au over 5.7 metres in a gabbro dyke containing 1-2% pyrite.
Qualified Person
The scientific and technical content of this press release has been reviewed by Mr. Jean Philippe Desrochers, PhD, P.Geo. Senior Project Manager for the Windfall Project, Qualified Person as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101").
Quality Control
True widths are estimated at 65-80% of the reported core length intervals. Assays are uncut except where indicated. Intercepts occur within geological confines of major zones but have not been correlated to individual vein domains at this time. Reported intervals include minimum individual assays of 3.0 g/t Au and minimum weighted averages of 3.0 g/t Au averaged over core lengths of a minimum of 2 metres. All NQ core assays reported were obtained by either 1 kg screen fire assay or standard 50 gram fire-assaying-AA finish or gravimetric finish at ALS Laboratories in Val d'Or, Quebec or Sudbury, Ontario. The 1 kg screen assay method is selected by the geologist when samples contain coarse gold or present a higher percentage of pyrite than surrounding intervals. All samples are also analysed for multi-elements, including silver, using an Aqua Regia-ICP-AES method at ALS laboratories. Drill program design, Quality Assurance/Quality Control and interpretation of results is performed by qualified persons employing a QA/QC program consistent with NI 43-101 and industry best practices. Standards and blanks are included with every 20 samples for QA/QC purposes by the Corporation as well as the lab. Approximately 5% of sample pulps are sent to secondary laboratories for check assay.
