Exploration History

1942: Bedrock mapping by V.K. Prest of the Ontario Geological Survey (OGS). 1970: Reconnaissance mapping by Thurston and Carter for the OGS’ Operation Fort Hope. 1979: Diamond drilling by Hanna Mining Co., on an area to the west of, and overlapping, the Wabassi Property. 1980: Kerr Addison Mines Ltd., completed an airborne electromagnetic survey on an area north of the Wabassi Property. 1983: Kerr Addison Mines Ltd., undertook limited diamond drilling as follow-up to their 1980 airborne survey. 2003: Ontario Geological Survey flew an airborne magnetic survey as part of the Fort Hope geophysical program. 2011: The Tempest group of claims were acquired for Northern Shield. 2011: Geotech Ltd. flew a helicopter-borne VTEM survey over the Tempest Property for Northern Shield Resources. 2011: Three diamond drill programs were performed on the property totalling 12 holes and 4,791 m. 2012: Geotech Ltd. flew a helicopter-borne VTEM geophysical survey over Northern Shield and Discovery Harbour’s Wabassi and Storm Group of Properties (The Storm Claim Group consists of 6 claims blocks identified as Tempest, Typhoon, Blizzard, Squall, Gale and Monsoon). 2012: A high-resolution ground magnetic geophysical survey was completed on the Tempest Property by consultants Gary Smith and Glenn O’Keefe. The goal of the survey was to enhance the understanding of the geometry and location of the magnetic response from the massive sulphide body to assist in the positioning of future drilling. 2013: A structural geology study was conducted on several drill holes from the Tempest 1 grid. The structural study included additional logging, sampling and structural interpretation of holes 11TP-01, 02, 03 and 12TP-04, 07,08, 09, 10, 11 and 12. 2016: Wabassi Resources acquired the Tempest Property from Northern Shield and subsequently staked additional claims to form a contiguous property. 2016-2017: Compilation of geophysics and a new interpretation of geological data combined with re-examination and sampling of core from holes drilled by Northern Shield Resources.

Geology Comments

Aug 20, 2018 (Greg Paju) - From AFRI 20000008159: The Tempest Zone is located in the Archean Miminiska-Fort Hope greenstone belt in the Uchi Domain (2.8-2.9 Ga) of the Superior Province’s Sachigo Superterrane. (Stott and Rayner, 2004, Stott et al., 2007 and Stott, 2007a-b). However, the subdivisions of the North Caribou Terrane are based mostly on work carried out on the western portion of the Sachigo Superterrane and since there is very little data available in the area of the Tempest Zone, these boundaries remain highly speculative.

Lithology

Lithology Comments

Aug 20, 2018 (Greg Paju) - Geology on the property consists of a succession of deformed, greenschist facies metavolcanic rocks. The succession is E-W trending with a well-defined S1 foliation oriented approximately E-W and dipping steeply to the south, a less well defined S2 axial planar foliation dipping to the SW and a locally strong lineation possibly plunging steeply to the WSW. The overall stratigraphy from south to north consists of mixed mafic and felsic volcanic flows including some breccia, mafic tuff and argillaceous tuff, in the area of the main Tempest mineralization, a 200-metre thick intermediate pyroclastic unit separates the two “exhalative” horizons. Silver-rich mineralization was intersected in association with stringer, semi-massive and massive sulphides dominated by pyrite and pyrrhotite, and is hosted in intensely altered felsic volcanic rocks.

Mineralization

Mineralization Comments

Aug 20, 2018 (Greg Paju) - From AFRI 20000014870, 20000008883, 20000008159, OFR6272 and OFR6284: Silver-rich mineralization was intersected in association with stringer, semi-massive and massive sulphides dominated by pyrite, pyrrhotite, minor sphalerite and trace arsenopyrite, and is hosted in intensely altered felsic volcanic rocks. According to Colin Bowdidge, the gold mineralization at Tempest is epigenetic, but possibly formed by remobilization of volcanogenic gold. Its juxtaposition and partial overlap with a silver zone is probably coincidental. The gold is hosted in a silicified zone with minor quartz veining and associated with trace sulphides (seen in DDH 12TP-07), and as visible gold in near surface laminated quartz vein (seen in DDH 12TP-12). The silver mineralization is associated with stringer, semi-massive and massive sulphides dominated by pyrite and pyrrhotite and hosted by intensely altered metavolcanic rocks. Alteration of the Tempest property consists of chlorite, muscovite, Fe-Oxide and minor sericite. Chlorite alteration is variable and occurs throughout the stratigraphy independently of lithology. Silicification, quartz veining, carbonatization and Fe-carbonate alteration are common throughout most of the stratigraphy. Sulphides are generally associated with chlorite, carbonate, silica alteration, and quartz veins Some highlights of the drilling on the Tempest property are from DDH 11TP-01 (extended) which intersected 1 m of 3% Zn and 16.7 m of 29.6 g/t Ag; DDH 11TP-02 intersected 104.2m with 19 g/t Ag, this includes a higher grade interval of 51 g/t Ag over 19.8 meters. The highest silver value from this intersection assayed 195 g/t Ag over 1 meter. Bowdidge (2017) re-assayed some of the Tempest core as part of a study of the gold and silver mineralization. A few highlights of this program are 1 m in DDH 12TP-08 containing 0.009 g/t Au, 28.2 ppm Ag, 42 ppm Cu, 17 ppm Pb and 59 ppm Zn, and DDH 12TP-07 with 1 m containing 0.082 g/t Au, 2.2 ppm Ag, 25 ppm Cu, 34 ppm Pb and 48 ppm Zn.
