Feb 09, 2011 (C Ravnaas) - The Goliath Project is located within the Wabigoon Subprovince of the Archaean Superior Province, northwestern, Ontario and is situated north of the Wabigoon Fault. Much of the Project area is underlain by the Thunder Lake Assemblage, an upper greenschist to lower amphibolite metamorphic grade volcanogenic-sedimentary complex of felsic metavolcanic rocks and clastic metasedimentary rocks (Beakhouse 2000). The assemblage comprises quartz-porphyritic felsic to intermediate metavolcanic rocks represented by biotite gneiss, mica schist, quartz-porphyritic mica schist, a variety of metasedimentary rocks and minor amphibolites. Compositional layering in metasedimentary rocks strikes ~70° to 90° and dips from 70° to 80° south-southeast. The Thunder River Mafic Metavolcanic rocks underlie the south part of the Property. The mafic rocks are generally massive flows but are pillowed locally and include amphibolite and mafic dykes, which are characterised as chlorite schists. Reference: Treasury Metal Inc.

Feb 09, 2011 (C Ravnaas) - The mineralised zones are tabular composite units defined on the basis of anomalous to strongly elevated gold concentrations, increased sulphide content and distinctive altered rock units and are concordant to the local stratigraphic units. Stratigraphically, gold mineralisation is contained in an approximately 100 to 150 metre wide central zone composed of intensely altered felsic metavolcanic rocks (quartz-sericite and biotite-muscovite schist) with minor metasedimentary rocks. Overlying hangingwall rocks consist of altered felsic metavolcanic rocks (sericite schist, biotite-muscovite schist and metasedimentary rocks), with the footwall comprising metasedimentary rocks with minor porphyries, felsic gneiss and schist. Gold within the central unit is concentrated in a pyritic alteration zone, consisting of quartz-sericite schist (MSS), quartz-eye gneiss and quartz-feldspar gneiss. Reference: Treasury Metal Inc.

May 19, 2016 (C Ravnaas) - The main zones of mineralisation (Thunder Lake Deposit) project to surface approximately 250- 300 metres north of Norman Road. The Main Zone, Footwall Zone (B, C and D subzones), and Hangingwall Zone (H and H1 subzones) of the Thunder Lake Deposit strike approximately eastwest, varying between 090° and 072°, with dips that are consistently 72°-78° toward the south or southeast. The main area of gold, silver and sulphide mineralisation and alteration occurs up to a maximum drill-tested depth of ~805 metres (TL135) below the surface, over a strike-length of approximately 2,300 metres within the current defined resource area. The high-grade shoots are interpreted to be the result of tight folding of the mineralised horizon (gold concentrated in fold noses) and appear to occur at regular intervals. Very rare flakes of aquamarine green mica (fuchsite: Cr muscovite) occur in the strongly altered sericite alteration with high-grade gold. Usually, mineralised intervals are narrow (up to 0.5 metres) zones enriched with 3-10% visible sulphides (pyrite, sphalerite, galena, chalcopyrite ± arsenopyrite, ± dark grey needles of stibnite) within a wider quartz-sericite or biotite-feldspar sections with fine-grained disseminated pyrite located in the foliation planes. Bulk Sampling: 428 oz Au and 1161 oz Ag from 2365 t. A bulk sample was taken in 1998 and the average grade of No 1 shoot was 11.16 g/t Au, and No 2 shoot was 3.53 g/t Au. A total of 682 ounces of gold was retrieved from a bulk sample. As a result of underground program, the deposit is interpreted as a series of high-grade, sulphide-rich shoots within a segment of a continuous zone of deformation and alteration that can be traced over 1.4 km to a depth of 700 m.
May 19, 2016 (Therese Pettigrew) - The discovery hole (TL-1) on the Main Zone of the deposit intersected three significant zones of polymetallic disseminated sulphide mineralization containing gold: Zone A returned 2.23 g/t Au, 18.9 g/t Au, 0.63% Zn over 6.1 m (80.0 to 86.1 m) including 5.25 g/t Au, 16.8 g/t Ag, 0.28% Zn over 1.9 m; Zone B intersected 0.97 g/t Au over 10.4 m (107.4 to 117.8 m) in a pyritic alteration zone; and Zone C assayed 7.99 g/t Au, 16.5 g/t Ag and 0.61% Zn over 6.1 m (196.7 to 202.8 m) including 17.49 g/t Au, 33.6 g/t Ag and 0.42% Zn over 2.6 m. Since 1990 the main resource area has been defined by extensive diamond drilling efforts concentrated over a strike length of over 2.0 km. To date, 10 zones containing gold and silver mineralization have been identified within the Central Unit of the main deposit. From south to north, they are the: a) Hanging Wall Zones (HW1 to HW4 Subzones) hosted in mostly biotite-muscovite schist (BMS) rock units and small amounts of metasedimentary and porphyry intrusive rocks; b) Main Zone (M1 and M2 Subzones) which is 5 to 40 m wide and occurs principally in silicified and sulphide mineralized (sphalerite, galena and pyrite) muscovite-sericite schist (MSS) rocks; c) B1 and B2 Zones hosted in BMS rocks residing between the Main and C Zones; d) C Zone (C1 and C2 Subzones) hosted in silicified and sulphide-bearing (sphalerite and galena) MSS Rocks; and e) D and E Zones hosted in mostly a mixture of MSS and BMS rocks surrounded by significant amounts of metasedimentary rocks and minor porphyry intrusive rocks. The majority of the historical gold and silver resource estimates reside in the Main Zone and C Zone. Visible gold and/or electrum are often rare and occur mainly within the leucocratic bands of MSS but can also in the melanocratic bands enriched with biotite and chlorite. In general, the highest gold and silver values occur in association with very strong pervasive quartz-sericite alteration (Puritch et al., 2015).
