Oban Mining Corporation ("Oban" or the "Corporation") is pleased to announce new results from the ongoing drill program at its 100% owned Windfall Lake gold project located in Urban Barry Township, Québec. 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 4 new drill holes include: 11.39 g/t Au over 19.9 metres, including 20.32 g/t Au over 7.5 m in DDH OBM16-603, and 13.75 g/t Au over 5.0 metres in DDH OBM-16-606. The table below outlines significant results from the new drill holes(1)(2):
||Footwall of Caribou|
||Footwall of Zone 27|
(1) For complete drilling results please see 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.
Drill Hole Collar Coordinates and Information:
Drilling above Red Dog is focused on expanding the known zones and upgrading the level of confidence in the mineral resource. Drilling below Red Dog is focused on testing three major corridors of mineralization and alteration (FW-1, FW-3, FW-4) oriented ENE and dipping steeply to the SE, similar to the known lenses of the Main Zone defined above Red Dog. Some of the deeper holes are designed to test gold mineralization both above Red Dog and the corridors of mineralization and alteration below Red Dog.
OBM-16-601 (section 2600) targeted the Caribou zone at 175 metres below surface. The large alteration corridor associated with the Caribou zone was intersected from 177.8 to 238.0 metres. It corresponds to a moderately silicified and sericitized rhyolite with 1-2% pyrite and cross-cut by variably mineralized metric-scale porphyry dykes. The footwall portion of the Caribou lens assayed 5.43 g/t Au over 2.4 metres in a strongly sericitized sheared rhyolite carrying 2-5 percent pyrite.
OBM-16-603 and OBM-16-604 (section 2150) targeted Zone 27 in a poorly drilled area previously estimated to be of low grade. The intersected Zone 27 consists of 1-10% pyrite in stringers and disseminations with local visible gold. OBM-16-603 returned 11.39 g/t Au over 19.9 metres including 20.32 g/t over 7.5 metres and 141.5 g/t Au over 0.3 metres at the contact between a rhyolite and a porphyry dyke. OBM-16-604 was drilled 34 meters below OBM-16-603 and returned 4.29 g/t Au over 3.0 metres. Those two intercepts confirm the high grade extension of Zone 27 on this section for more than 140 m vertically where historical intersections returned 12.84 g/t Au over 3.0 metres and 8.87 g/t Au over 5.0 metres. Additional gold mineralization was present some 30 metres after Zone 27 in OBM-16-603 with 4.31 g/t Au over 2.5 metres in a bleached andesite with 3-5% pyrite in stringers and disseminations.
OBM-16-606 (section 2175) was drilled on Zone 27 and 34 metres to the east of OBM-16-603. It returned 13.75 g/t Au over 5.0 metres, including 76.85 g/t Au over 0.8 metres at the contact between a strongly silicified rhyolite and a porphyry dyke and containing up to 10% pyrite. This intersection is located some 50 metres above EAG-13-527 that returned 415.7 g/t Au over 7.8 metres.
The scientific and technical content of this press release has been reviewed by Mr. Gernot Wober, P.Geo. Vice President Exploration for Oban Mining Corporation, Qualified Person as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101").
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 diluted over core lengths of at least 2.0 metres. All NQ core assays reported were obtained by either 1 kilogram screen fire assay or standard 50 gram fire-assaying-AA finish or gravimetric finish at ALS Laboratories in Val d'Or, Québec or Sudbury, Ontario. The 1 kilogram 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.
About the Windfall Lake Gold Deposit
The Windfall Lake gold deposit is located between Val-d'Or and Chibougamau in the Abitibi region of Québec, Canada. The current mineral resource comprises 2,762,000 tonnes at 8.42 g/t Au (748,000 ounces) in the indicated category and 3,512,000 tonnes at 7.62 g/t Au (860,000 ounces) in the inferred category (NI 43-101 compliant report dated November 13, 2014). The Windfall Lake gold deposit is currently one of the highest grade resource-stage gold projects in Canada. The bulk of the mineralization occurs in the Main Zone, a southwest/northeast trending zone of stacked mineralized lenses, measuring approximately 600 metres wide and at least 1,400 metres long. The deposit is well defined from surface to a depth of 500 metres, and remains open along strike and at depth. Mineralization has been identified only 30 metres from surface in some areas and as deep as 870 metres in others, with significant potential to extend mineralization up and down-plunge and at depth.
