About Torr Resources Corp.

Torr Resources Corp. (The Company) is a private, Canadian-based mineral exploration company actively exploring its 100% owned Fire Mountain Project with Cu-Au skarn-porphyry mineralization in the heart of BC’s historic New Westminster Mining District. The Company is also evaluating its newly acquired 100% owned Bendor Project with Au-vein mineralization, located within the highly productive Bridge River gold belt. We bring a new perspective to proven districts of the southern Canadian Cordillera by looking at large-scale crustal controls that improve the identification of potentially large mineral system emplacement. Our objective is to generate future projects by identifying and advancing previously undervalued assets within cost-effective districts that contain highly prospective targets.

Management and Technical Team

Malcolm Dorsey, President/Director: Malcolm Dorsey is an exploration geologist who has spent his career on a broad range of consultant and management projects in the mining and petroleum industries in western North America since 2011. He has extensive knowledge in mineral exploration related to skarn, vein-gold, VMS, and lead-zinc deposits along the Coast-Cascade Orogen of British Columbia. His completion of an MSc thesis in Structural Geology at the University of Calgary honed his technical skills and knowledge on structurally-controlled ore generation along the Coast-Cascade Orogen, having focused on re-characterizing district-scale structures of the historic Westminster Mining District of southwest British Columbia. Most recently he has consulted for early and late-stage exploration and mining projects in central and northwest British Columbia, including epithermal and mesothermal vein-gold, polymetallic-veining, VMS, and intrusion-related gold-veining. Previously he has consulted on lead-zinc and skarn-gold exploration in southern British Columbia, in addition to more advanced projects including banded iron formation gold deposits in Nunavut, VMS in Saskatchewan, and epithermal vein-gold in Nevada.

Cameron Dorsey, VP Exploration: Cameron Dorsey has overseen and participated in several successful exploration programs throughout Nunavut, Yukon, British Columbia, Quebec, and Alberta since 2011. He has experience in both grassroots and advanced exploration programs, specializing in VMS and vein-gold exploration. In his most recent role as a Project Geologist, he supervised exploration programs for Sabina Gold & Silver in the Back River Gold District, an emerging gold district in Nunavut. Cameron Dorsey holds a degree in Geology and an MSc in Structural Geology from the University of Calgary. His MSc thesis was focused on the linkages between the Insular Superterrane and North American margin as recorded by the Late Cretaceous Queen Charlotte Group in Northwest British Columbia, a region closely associated with one of Canada’s premier mining districts.

Cu-Au-Fe Skarns in British Columbia

• Wrangellia and Quesnellia terranes have the greatest size, number, and metal production for Fe and Au skarns in British Columbia (Ray et al. 1995)

• Wrangellia also contains 173 (51%) total known Cu skarn occurrences in British Columbia, while Quesnellia contains 64 (19%) (Ray and Webster 1997). The Fire Mountain Project is located on the eastern margins of Wrangellia within the Cascade Magmatic Arc Porphyry Belt

• Based on 2019 field analysis and comparisons made by Ray (2013), the Fire Mountain Property contains stratiform mineralization with similar tectonic settings to a number of Cu skarn-porphyry deposits including 10) Craigmont; 12) Greenwood (Phoenix); 17) Copper Mountain-Ingerbelle (porphyry-related); 19) Galore Creek (porphyry-related); 9) Whitehorse Cu Belt (Copper King, Carlisle, Pueblo, Valerie, Grafter, Arctic Chief, War Eagle)

• The Fire Mountain Project is largely underexplored and has never been drill tested

• The Fire Mountain Project is situated within the Miocene Arc of the Pemberton Belt

• Also known as the Cascade Magmatic Arc Porphyry Belt, which extends from British Columbia to Oregon State

• The Cascade Magmatic Arc Porphyry Belt consists of Late Cretaceous to Paleogene plutonism above an active subduction zone

• The Miocene Arc contains numerous porphyry deposits, including the Giant Copper Deposit (4.5 Mt 0.47% Cu, 0.38 g/t Au, 11.19 g/t Ag) (Schroeter 1999) in British Columbia, as well as the Margaret Deposit (523 Mt 0.36% Cu, 0.24 g/t Au, 1.6 g/t Ag), and Glacier Creek Deposit (1.7Bt 0.33% Cu) (Singer et al. 2008) in Washington State

Figure modified from Wells and McCaffrey (2013).

Regional GeologyUnderexplored with Cu-Au skarn-porphyry correlations to the Copper Mountain-Ingerbelle Deposits

• Fire Mountain Project – Land Selection Criteria

• Major NW-SE longitudinal structures – potential crustal-scale marking the eastern boundary of the Wrangellia Terrane, could provide structural control of stratiform ore lenses as at the Copper Mountain-Ingerbelle Deposit

• Bend in major steeply-dipping structures (FCF=Fire Creek Fault) with distinct calcareous sedimentary and volcanic host rocks within the historically productive Gambier Group – excellent stratigraphic, geochemical, and structural ground preparation for concentration of Cu-Au mineralization

• Large NE structures - including the regionally extensive Glacier Creek Fault, likely act as conduits for mineralized Miocene intrusives such as the proximal Rogers Creek Pluton

Figure compiled and modified from Bustin et al. (2013), Journeay and Friedman (1993), and Brown et al. (2000).

Glacier Lake Fault

Fire Creek Fault

Map based on Lynch (1992) and field interpretations by Torr Resources Corp.

• ~10 km of strike-parallel to major shearing along the potentially crustal-scale Fire Creek Fault and bounded to the west by the major Glacier Lake Fault

• Regional-scale opportunity within the Miocene Arc of the Cascade Magmatic Arc Porphyry Belt

• Calcareous volcanic host rocks are both chemically reactive and physically capable of maintaining long-lived permeability - traits essential for megaskarn deposits in the Canadian Cordillera

Fire Mountain Project - Potential Cu-Skarn

Fire Mountain Project – Cu-Au Skarn Mineralization (porphyry-related)

• Significant Au, Cu, and Co mineralization is associated with magnetite veins, lenses, and blebs that are most common near an interpreted transitional potassic zone

• An iron oxide plot (Dupuis and Beaudoin 2011) suggests magnetite on Fire Mountain is geochemically similar to skarn-type deposits

• Potentially sourced from the Rogers Creek Pluton - host to a number of prospective Cu-porphyry zones

Fire Mountain Project - Cordillera Skarn Development

Figure modified from Ray (2013).

• The Fire Mountain Property is strongly structurally-controlled by two large NW and NE-trending fault-shear systems (Fire Creek Fault and Glacier Lake Fault), intruded by the Miocene Rogers Creek Pluton - host to a number of Cu-porphyry prospects

• Faults, dikes, and sill margins related to the major NW and NE-trending structures together with bedding and lithologic contacts have likely acted as conduits and a focus for hydromagmatic fluids during skarn development

• Cu skarns hosted by mafic tuffs (examples include the Copper Mountain-Ingerbelle deposit) have an exoskarn of epidote, actinolite, biotite, chlorite that is also typical of alteration identified on Fire Mountain

• The Fire Mountain Property contains numerous occurrences of sulphide precipitation within an exoskarn envelope associated with late hydromagmatic retrograde alteration

Fire Mountain Project - Selection Criteria

Discrete shears within an ~81m - wide shear corridor containing NW-trending quartz-sulphide veinlets concentrated along the contact between volcanic breccia (KBHv) and overlying tuff (KBHI)

A Jog in major NW-striking Fire Creek Fault with historic shear-parallel Cu-Au veins - geometry favorable to focusing metal-rich hydromagmatic fluids

Magnetite veins and lenses up to 10 cm thick are typically crosscutting the shear zone, increased dilation was observed within more competent host rock (KBHv)

Northeast-trending structures including the Glacier Lake Fault are likely conduits for mineralized Miocene intrusives such as the Rogers Creek Pluton

Total Magnetic Intensity - Historic

Airborne magnetometer surveys were conducted simultaneously at Fire Mountain and Doctors Point (~35km to the southeast) in 1983. Drill core at Doctors Point outlined a direct association of high magnetic intensity with high susceptibility minerals including pyrite, arsenopyrite, and gold mineralization

Head of the anomaly shows steep magnetic gradients suggesting good chemical activity

Major lenticular magnetic anomaly appears to parallel the mapped Fire Creek Fault - suggestive of strong structural controls
