The "Aurizon Gold Zone (or Zone 3 Anomaly)" on the Ann 1 Claim is located 4 kilometres southeast of Peach Lake, approximately 21 kilometres northeast of Lac La Hache and is readily accessible from Highway 97 via a network of logging roads. Other names for the Ann claims and showings have been the Peach and the Ophir. The Aurizon showing is one of several copper showings on the current Ann 1 and 2 claims (see also 092P 002, 035, 109, 153 and 174). All of these occurences are part of the Spout Lake copper-gold district, a group of porphyry and skarn deposits associated with Later Triassic to Early Jurassic alkaline intrusive rocks of the Spout Lake intrusive suite.

The Ann (Peach) property is underlain by andesites, basalts, calcareous tuffs and argillites of the Upper Triassic Nicola Group (Assessment Report 25368). Nicola Group rocks are intruded by the Late Triassic to Early Jurassic Spout Lake Intrusive complex, an alkalic intrusive suite ranging in composition from pyroxenite through monzonite to syenite, and from batholithic size to small intrusive plugs, dykes and breccia bodies. Granodioritic rocks of the Triassic to Jurassic Takomkane Batholith intrude Nicola rocks east of the property. Outliers of alkaline plateau basalts of the Miocene to Pleistocene Chilcotin Group are present in the general area.

No good description of the Aurizon Gold Zone is available, however Assessment Report 23975, states that the area contains pyrite, chalcopyrite, magnetite and traces of bornite, native copper and tetrahedrite as dissemingations and in veinlets and stockworks. K-feldspar, silica, epidote (propylitic) and clay alteration are associated with the minralisation which occurs along fracture zones and is hosted in hydrothermal breccias cutting monzodiorite.

At least two other zones of mineralization, referred to as the Aurizon Central and Aurizon South zones, have also been identified in outcrop and by diamond drilling on the Ann 1 claim.

The Aurizon Central zone, identified in outcrop in 2000, comprises a potassic-altered monzonite hosting native copper.

The Aurizon South zone, identified by drilling (hole AZS08-07) in 2008, comprises a hydrothermal breccia cutting a potassic-altered monzonite. The matrix of the host breccia is hematitic rather than magnetite-bearing. The zone has been tested by drilling over a strike length of approximately 300 metres along a strike of approximately 020 degrees and is approximately 28 metres thick at a depth of 250 metres below surface. Visible gold has been identified in two drill holes (AZS16-56 and -57) associated with pyrite, chalcocite and chalcopyrite.

Work History

Interest in the Spout Lake area was triggered in 1966, when the Geological Survey of Canada released the results of a regional airborne magnetic survey that outlined an annular magnetic anomaly, 10 kilometres in diameter, in the Spout Lake area and included the area underlying the Peach 1 (MINFILE 092P 001) prospect. Subsequently, in 1966 and 1967, Coranex Limited obtained anomalous results in follow-up stream sediment geochemical surveys and soil geochemical surveys in the area south of Peach Lake. Programs of geological, soil geochemical, magnetometer, induced polarization and prospecting surveys were undertaken in 1967 in the area south of Peach Lake, leading to the discovery of the Peach 1 and several other occurrences. Asarco Exploration Company of Canada Limited optioned the property in 1969.

Amax Potash Limited optioned the property between 1971 and 1973 and completed programs of geological mapping, geophysics and percussion drilling. In 1983 and 1984, the Selco Division of BP Resources Canada Limited completed soil geochemical surveys on the Core group of claims which covered the property.

G.W.R. Resources Inc. acquired the property in 1988 and Asarco re-optioned the property and completed induced polarization surveys and percussion drilling in 1991. In 1993, G.W.R. Resources Inc. formed a joint venture with Regional Resources and have since completed programs of induced polarization and diamond drilling. Two diamond drillholes totaling 406.3 metres were completed in 1994 by G.W.R. Resources Inc. Drilling was done to determine structure, geology, alteration and copper-gold content of a combined IP, soil geochemistry and airborne magnetic anomaly.

In 1995, G.W.R. Resources Inc. completed three diamond drillholes at the Aurizon Gold zone to follow up the findings in 1994. Highlights include drillhole A95-02, which returned a 6 metre core length that assayed 1.13 grams per tonne gold and 0.18 per cent copper (Assessment Report 25368).

In 2000, a drill hole (AZ00-1) on the main Aurizon zone yielded 0.22 per cent copper and 0.39 gram per tonne gold over 46.5 metres (SRK Consulting (Canada) Inc. (2012-06-04): Independent Technical Report for the Lac La Hache Project).

In 2006, G.W.R. Resources Inc. conducted an exploration program of 3178 metres of trenching and 5638.7 metres of diamond drilling. The drilling program was carried out to test the depth of extensions of copper mineralization in exposed bedrock in the southeastern area of the Aurizon Gold zone. Highlights include drillhole AZ-06-01, which returned 44 metres grading 0.42 per cent copper and 0.63 grams per tonne gold (Assessment Report 29746).

In 2007, GWR Resources completed a further 15,325.4 metres of diamond drilling in 43 holes and 3178 metres of trenching on the Aurizon occurrences. Drilling on the main Aurizon zone yielded intercepts of up to 0.07 per cent copper with 2.77 grams per tonne gold over 20.7 metres in hole AZ07-11 and 0.39 per cent copper with 0.61 gram per tonne gold over 90 metres in hole AZ07-21 (SRK Consulting (Canada) Inc. (2012-06-04): Independent Technical Report for the Lac La Hache Project).

In 2008 and 2009, an additional 48 and 20 diamond drill holes were completed on the Aurizon Central and Aurizon South zones, respectively. A drill hole (AZS08-07) on the Aurizon South zone yielded 0.87 per cent copper, 4.8 grams per tonne silver and 6.28 grams per tonne gold over 26 metres, including 1.92 per cent copper, 7.6 grams per tonne silver and 15.5 grams per tonne gold over 6 metres, while drilling on the main Aurizon zone yielded intercepts including 0.37 and 0.23 per cent copper with 0.95 and 0.92 gram per tonne gold over 94 and 137 metres, respectively, in holes AZ08-74 and AZ08-78 (SRK Consulting (Canada) Inc. (2012-06-04): Independent Technical Report for the Lac La Hache Project).

In 2010, seven drill holes, totalling 2435.2 metres, were completed on the Aurizon Central zone and six holes, totalling 2934.9 metres were completed on the Aurizon South zone. Drilling on the Aurizon Central zone yielded intercepts including 0.26 per cent copper and 0.29 gram per tonne gold over 15 metres and 0.77 per cent copper with 0.98 gram per tonne gold over 6 metres in hole AZ10-110, while drilling on the Aurizon South zone yielded intercepts including 0.59 per cent copper and 4.94 grams per tonne gold over 10 metres in hole AZS10-21, 0.27 per cent copper with 0.59 gram per tonne gold over 34 metres in hole AZS10-24 and 2.64 per cent copper with 9.66 grams per tonne gold over 2 metres in hole AZS10-25 (SRK Consulting (Canada) Inc. (2012-06-04): Independent Technical Report for the Lac La Hache Project).

In 2011 and 2012, eight drill holes, totalling 3207.3 metres, were completed on the Aurizon South zone. Drilling yielded intercepts including 0.24 per cent copper with 0.51 gram per tonne gold over 120 metres, including 0.43 per cent copper with 1.51 grams per tonne gold over 32 metres in hole AZS11-30, 9.30 per cent copper, 48.1 grams per tonne silver and greater than 10 grams per tonne gold over 2 metres in hole AZS11-29, 0.92 per cent copper and 3.40 grams per tonne gold over 12 metres in hole ZS12-33 and 0.30 per cent copper with 0.42 gram per tonne gold over 172 metres in hole AZS12-34 (SRK Consulting (Canada) Inc. (2012-06-04): Independent Technical Report for the Lac La Hache Project).

Further drilling, prospecting and geochemical sampling programs were completed in 2015 and 2016, to expand the overall size of the Aurizon South deposit and identify new zones of high-grade mineralization within the main structure. This work included 21 holes, totalling 6684.9 metres, and trenching. In May 2016, GR Resources Inc. was renamed EnGold Mines Ltd. Drilling on the Aurizon South zone yielded intercepts including 1.70 grams per tonne gold and 0.44 per cent copper over 23.00 metres in hole AZS15-48 and 7.74 grams per tonne gold, 6.53 grams per tonne silver, 1.26 per cent copper over 10.00 metres in hole AZS15-42, 18.54 grams per tonne gold, 37.96 grams per tonne silver and 1.49 per cent copper over 3.05 metres in hole AZS16-53, 263.00 grams per tonne gold, 90.50 grams per tonne silver and 1.74 per cent copper over 0.10 metre in hole AZS16-56 and 4.80 grams per tonne gold with 1.25 per cent copper over 6.85 metres in hole AZS16-61 (Kirkham, G. (2018-03-05): NI 43-101 Technical Report Mineral Resource Estimate for the Aurizon South Deposit, Lac La Hache Project). Visible gold was reportedly identified in holes AZS16-56 and -57.

Subsequent trenching of the gold-bearing quartz veins yielded values of up to 177.5 grams per tonne gold, 80.9 grams per tonne silver and 7.46 per cent copper (Sample 7; Kirkham, G. (2018-03-05): NI 43-101 Technical Report Mineral Resource Estimate for the Aurizon South Deposit, Lac La Hache Project).

In 2017, a further program of drilling, comprising three holes, and a 641 line-kilometre airborne high-resolution gravimetric and magnetic gradient survey were completed on the area.

In 2017, EnGold Mines released a mineral resource estimate for the Aurizon South zone of 1,073,000 tonnes inferred grading 2.48 grams per tonne gold, 5.98 grams per tonne silver and 0.64 per cent copper, using a 2.5 grams per tonne gold equivalent cut-off (Kirkham, G. (2018-03-05): NI 43-101 Technical Report Mineral Resource Estimate for the Aurizon South Deposit, Lac La Hache Project).

During 2018 through 2020, EnGold Mines Ltd. completed programs of prospecting, soil sampling, diamond drilling and a geophysical survey on the area as part of the Lac La Hache property.

In 2018, follow-up prospecting of a gold-in-soil anomaly located upslope (southwest?) of the area drilled previously on the Aurum Gold occurrence identified a new zone(s) of quartz-veined outcrop, later referred to as the 22, 23 and PG zones, yielding values of up to 25.6 grams per tonne gold, 41.5 grams per tonne silver and 3.97 per cent copper, whereas in 2020 another zone of gold-bearing quartz veins with limonitic gouge was identified approximately 160 metres north of the 2018 veined zone and yielded up to 263 grams per tonne gold in bedrock grab samples (SRK Consulting (Canada), Inc. [2021-05-11]: Independent Technical Report for the Lac La Hache Project, Canada).

In 2018, drilling on the PG zone yielded intercepts including13.60 and 5.82 grams per tonne gold, 12.6 and 5.5 grams per tonne silver with 1.87 and 0.16 per cent copper over 0.94 and 3.90 metres in holes 18-68 and 18-69, respectively (SRK Consulting (Canada), Inc. [2021-05-11]: Independent Technical Report for the Lac La Hache Project, Canada).
