Orford Announces Multiple High-grade Gold Drill Intersections up to 13.7 g/t, New Surface Discoveries up to 457 g/t Au, Confirming 40-km High-grade Gold System at Qiqavik
TORONTO, Oct. 26, 2017 /CNW/ - Orford Mining Corporation ("Orford") (TSX-V: ORM) is pleased to announce multiple Au-Cu-Co drilling intersections and extensive new high-grade gold surface prospecting discoveries along the "Qiqavik Break" from the 2017 summer exploration program conducted at its 100% controlled Qiqavik Project in northern Quebec.
Highlights:
- Confirmed 2016 surface discoveries at Aurora, Esperance, and Esperance West with 14 of 19 drill holes intersecting gold mineralization: up to 13.7 g/t at Aurora, up to 8.8 g/t gold at Esperance, and 5.6 g/t Au at Esperance West with copper assays pending. (See Table 1 for highlights)
- Gold mineralization was successfully drill tested at Esperance along 300 metres of a 1.3 km structure, and at Esperance West along 650 metres of a 2.0 km structure
- Made 5 new surface discoveries at Aurora Central, Gerfaut South, Central Qiqavik, Horizon, and Focused Intrusive.
- Aurora Central: Sub-outcrop quartz veins yielding 457.4 g/t, Au 114.7 g/t Au and 112.1 g/t Au
- Gerfaut South: multiple high-grade boulders with significant amounts of visible gold yielding grades of 122.5 g/t to 285.2 g/t
- Central Qiqavik: Multiple mineralised zones yielding 14 samples grading from 5 g/t to 114 g/t in a 2 km by 2 km area
- Horizon: channel sample of 5.6 g/t over 0.9 m
- Focused Intrusive: Local quartz vein blocks yielding values up to 8.93 g/t Au
David Christie, President and CEO of Orford, commented, "We are very encouraged by these results, which display the tremendous potential of this discovery in a new gold belt located in a previously unexplored region of Canada. In nine short weeks of exploration, we have made three drill-confirmed high-grade discoveries that each extend over hundreds of meters. We have also made five new high-grade gold prospecting discoveries at surface that remain untested by drilling. A substantial portion of the property is left to be explored. As the "first boots" on the ground, Orford has been able to identify a significant structural break, the Qiqavik break, across our 40 km long property that holds huge potential for an economic gold discovery. This is in much the same way as the Larder Lake-Cadillac break in the Abitibi, the Boulder-Lefroy Fault System in Kalgoorlie, Australia and the Ashanti Fault System in West Africa."
Qiqavik 2017 Exploration Program and Results
The 2017 summer exploration program at Qiqavik consisted of 2,723 metres of diamond drilling in 23 holes (Table 1), 721 line-kilometres of airborne (drone) magnetic surveying, 105.6 line-kilometres of Abitibi Geophysics ground OreVisionTM IP surveying, prospecting, mapping, surface rock sampling, and till sampling (Figure 1). Details of the work program are available in the 43-101 Technical Report on the Qiqavik Property filed under Orford's profile on SEDAR and on Orford's website. This work has led to the better understanding of the surface occurrences discovered in 2016 and to the identification of many additional mineralized occurrences on the property.
Gold and multi-element assay results have been received for the drilling and surface sampling programs with the exception of multi-element results from holes QK-17-017, -019, -020, -021, -022, -028 and -029, and 116 grab samples. These assays are pending and are expected to be received and published in early November. A summary of significant assay results from the drilling program and surface sampling program are presented below. A table of complete results can be accessed at Table 3.
Drilling has confirmed the subsurface extent of the structures and the Au and Au-Cu-Co mineralization associated with the 2016 surface gold discoveries at Esperance, Esperance West, and Aurora.
Work completed during the 2017 program demonstrates that gold is associated with secondary splay structures located along the district-scale Qiqavik Break Shear Zone which extends the full 40 km length of the Qiqavik Property. Geological data indicate that gold mineralization at Qiqavik is structurally controlled and associated with porphyry intrusions in places. Typically, in structurally controlled gold deposits, the intensity of mineralization varies along the length of the structures with ore shoots focused in zones of dilation. Orford is currently analyzing airborne magnetic and field mapping data collected during the summer 2017 program to identify and locate sites of dilation along structures that were active at the time of gold mineralization in order to target significant gold mineralization accumulations.
The Qiqavik Break is part of the Cape Smith Belt event which is of Paleoproterozoic age (1.8-1.9 billion years). This geologic era is marked by its significant metal endowment as illustrated by the important gold districts that occur worldwide related to geological events of Paleoproterozoic age. These include the Flin Flon-Snow Lake Belt, the Ashanti Gold Fields of West Africa, the Tapajos-Parima Belt of Brazil, and the Tanami Region in Australia.

Esperance
At Esperance, drilling has outlined two Au-Cu-Co sulphide-rich mineralized zones, Esperance and Esperance West, that extend over a known strike length of 300m and 650m respectively (Figure 2). Results include 2.39 g/t Au, 0.26% Cu over 2.5m in QK-17-022 at Esperance and 2.63 g/t Au, (Cu pending) over 4.0m including 5.58 g/t Au, (Cu pending) over 1.0m in QK-17-008 at Esperance West. Multiple porphyry dykes were observed in the core at Esperance which may be related to mineralization.
The polymetallic mineralized trend continues West of Esperance along the Qiqavik Shear Zone where the new Horizon discovery has yielded 5.67 g/t Au over 0.9m in a channel sample at a distance of 1.0 km from the Esperance West drilling.

Sub-outcrop samples are taken from frost-heaved blocks that have been detached from the bedrock, but are still in place above their bedrock source. Boulder fields are extensive areas of angular boulders of the same lithology.
Aurora
At Aurora, drilling has intersected two quartz vein hosted gold mineralized zones, Aurora and Aurora West, separated by 1.6 km (Figure 3). Results include 2.55 g/t Au, over 2.2m including 13.68 g/t over 0.30 m in QK-17-009 at Aurora West, and 3.05 g/t Au over 1.8 m including 4.93 g/t Au 1.0m in QK-17-007 at Aurora. Approximately equidistant between these two zones, at Central Aurora, prospecting has yielded a new discovery of quartz veins with galena mineralization occurring along a West-Northwest shear zone. Sub-outcrop samples from this zone containing visible gold include samples grading 457.4 g/t, Au 114.7 g/t Au and 112.1 g/t Au.
Additionally, to the south of the main Aurora trend, many quartz vein boulders of proximal source containing polymetallic sulphide mineralization were discovered at the eastern contact zone of the Focused Intrusive. The mineralization and structures indicate multiple void filling events by mineralized fluids in an extension system. Assay results from grab samples from this area include 8.93 g/t Au and 4.25 g.t Au. This discovery was made in the last two days of the 2017 program.
Central
Initial drilling on structures at Central Qiqavik have yielded strongly altered shear zones with anomalous gold (up to 0.26 g/t over 3.0 m and 0.34 g/t over 1 m in QK-17-023) (Figure 4). Concurrent prospecting and mapping at Central Qiqavik in 2017 has led to the discovery of multiple new mineralised trends defined by high-grade surface grab samples over a 2.5 km by 2.5 km area including individual zones with samples grading up to 113.96 g/t, 24.46 g/t, 17.86 g/t and 20.44 g/t respectively. Follow-up of these discoveries will focus future targeting on the most prospective areas of Central Qiqavik.
Gerfaut
Prospecting in the Gerfaut Area has led to the discovery of multiple angular boulders containing visible gold in the Gerfaut South Area. Grab samples from these boulders have yielded high-grade gold values including 285.24 g/t, 253.64 g/t, 177.47 g/t and 122.52 g/t (Figure 5). These boulders occur 1 km southeast of and up-ice from the historical drill intersection of 3.08 g/t Au over 10.5 m in PAR96-01 and therefore likely represent a different source. Glacial transport is toward the NNE, and due to the proximity of the glacial divide field data suggest limited distance (50 to a few hundreds of metres) between the source of gold-bearing mineralization and boulders and related geochemical anomalies detected in till.
Qualified Person and Quality Assurance and Quality Control
The disclosure of scientific and technical information contained in this news release has been approved by Alger St-Jean, Vice President, Exploration of Orford, a Qualified Person under NI 43-101.
The work program at Qiqavik was supervised by Michelle Sciortino, Senior Project Geologist who is responsible for all aspects of the work, including the quality control/quality assurance program. On-site personnel at the project log and weigh all samples prior to sealing and shipping. Sample shipments are sealed and shipped to Techni-Lab, Sainte-Germaine-Boulé, Québec. All gold assays reported were obtained by either 350-g screen fire assay or standard 50-gram fire-assaying-AA finish or gravimetric finish (method 1A2-5 and 1A3-50) at. The 350-g screen assay method is selected by the site geologist or the lab when samples contain coarse gold or higher percentage of sulfide mineralization that may be associated with gold relative to surrounding intervals. All samples are also analyzed for multi-elements, including copper and silver, using a four-acid method with an ICP-EOS and ICP-MS finish at Techi-labs affiliated Actlabs in Ancaster, Ontario. Overlimits were analyzed by peroxide fusion with ICP-EOS finish. Drill program design, Quality Assurance/Quality Control ("QA/QC") 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 inserted at a minimum of 10% and 5% for core and grab samples respectively for QA/QC purposes in addition to those inserted by the lab. A subset of samples has not yet been sent for a verification assay at another lab.
Techni-Lab Laboratory, is a subsidiary of Act Labs, is accredited (n. 707) by the Standards Council of Canada and found to comply with the requirements of ISO/IEC 17025:2005 (CAN-P-4E) and CAN-P-1579.
