All such statements, other than statements of historical facts that address exploration drilling, exploitation activities and other related events or de
Slide 3: Lemare Cu-Au Porphyry Project
Lemare Cu-Au Porphyry Project Lemare is a Cu-Au porphyry prospect in the Jurassic Island Bonanza arc of northern Intrusions Vancouver Island Karmustsen Gp Significant past producing copper mines (Island Copper, Yreka), resources (Hushamu, Holberg volcanics Red Dog and NW Expo) and younger (Miocene)
Slide 4: Lemare Porphyry Cu-Au Project
Lemare Porphyry Cu-Au Project • Lemare is a large (5 x 3 km) alteration system in Jurassic Bonanza volcanic arc rocks of northern Vacouver Island. • Potential Island Copper / Hushamu porphyry copper analogue includes 10 MINFILE Cu and Au occurrences • A large lithocap is preserved on the property; a
Slide 5: Geology
Lemare Porphyry Cu-Au Project: Geology Lower Jurassic Bonanza Culleet Creek arc volcanics at Lemare are contained in two structural blocks separated by a NE trending fault. Lemare Lake Alteration in the Culleet Creek zone is hosted Northwest mainly in felsic volcanic unit lJBLvf. Block Alteration in
Slide 6: Alteration
Lemare Porphyry Cu-Au Project: Alteration A lithocap is preserved in the Southeast Block. Here, Culleet Creek extensive SCP (silica-clay / sericite-pyrite) alteration SCP includes advanced argillic alteration minerals : kaolinite, pyrophyllite, muscovite, illite, diaspore and zunyite (Keewatin and A
Slide 7: Cu in rocks, soils
Lemare Porphyry Cu-Au Project: Cu in rocks, soils Copper mineralization at Lemare occurs in the Northwest Culleet Creek Block at the Culleet Creek, New Destiny and Lake Zones Lake In the Southeast Block, copper is depleted (possibly leached) in the South Gossan Zone lithocap, but significant copper
Slide 8: Southeast Block
Lemare Porphyry Cu-Au Project: Southeast Block North of South Gossan in Dumortierite Creek, high grade copper mineralization is associated with porphyry-like CMG chlorite-silica- magnetite/hematite-pyrite (epidote, carbonate) alteration: Lake 131358 – 5.96% Cu, 154 ppb Au; coarse cpy-spec hematite;
Slide 9: Island Copper-like Alteration
Lemare Porphyry Cu-Au Project: Island Copper-like Alteration At Island Copper, > 0.5% Cu grade shells occur in close proximity to the pyrophyllite- dumortierite/chlorite-magnetite transition. At Lemare (Dumortierite Creek target area), historical work documents high grade Cu+/-Au occurrences hosted
Slide 10: South Gossan

Slide 11: Culleet Creek and New Destiny
Lemare Porphyry Cu-Au Project: Culleet Creek and New Destiny Mineralization at Culleet Creek is spatially associated with a 250x 500 m zone of K-feldspar-quartz-chlorite alteration. Hematite dusting, jasper and quartz stockworks are common. Petrogaphic studies note that the K-feldspar alteration is
Slide 12: Culleet Creek and New Destiny

Slide 13: Mo in rocks, soils
Lemare Porphyry Cu-Au Project: Mo in rocks, soils Although molybdenum Culleet Creek values are generally low over most of the project area, a subtle Mo Lake anomaly is expressed in soils west of Lemare Lake including the South Gossan zone New Destiny Dumortierite Creek South Gossan High grade Zn-Cu-
Slide 14: Au in rocks, soils
Lemare Porphyry Cu-Au Project: Au in rocks, soils Elevated Au values are Culleet Creek found at New Destiny (up to 3.47 g/t Au in rocks) and an unnamed zone of Zn-rich polymetallic mineralization Lake along the SW extension of the Dumortierite Creek fault (up to 8.48 g/t Au, 19.8% Zn New and 1.2% Cu
Slide 15: Geochem Zonation
Lemare Porphyry Cu-Au Project: Geochem Zonation Soil samples appear to Culleet Creek indicate a geochemical zonation outford from proximal Cu mineralization at Culleet Creek and Dumortierite Creek to distal Zn and Au zones southwest of Culleet Creek and east of Dumortierite South Gossan Zn Au Creek
Slide 16: Summary
Summary ✓ Lemare is road accessible, permitted for drilling, proximal to a deep water port and power, and can be explored year round. The project contains multiple underexplored or untested porphyry Cu-Au targets. ✓ Extensive documentation of geology and geochemistry at Lemare by historical explorat
