Forward Looking Statements or Information Related to Exploration:Relating to exploration, the identification of exploration targets and any implied future investigation of such targets on the basis of specific geological, geochemical andgeophysical evidence or trends are future-looking and subject to a variety of possible outcomes which may or may not include the discovery, or extension, or termination ofmineralization. Further, areas around known mineralized intersections or surface showings may be marked by wording such as “open”, “untested”, “possible extension” or“exploration potential” or by symbols such as “?”. Such wording or symbols should not be construed as a certainty that mineralization continues or that the character ofmineralization (e.g. grade or thickness) will remain consistent from a known and measured data point. The key risks related to exploration in general are that chances ofidentifying economical reserves are extremely small.

Located in British Columbia’s prolific ‘GOLDEN HORSESHOE’
Lawyers project is located within the northeastern region of the prolific metal-endowed Stikine terrane. Magmatic events in Stikinia duringthe Late Triassic and Early Jurassic are the driving source for the development of mineralizing porphyry and epithermal systems. On boththe east and west sides of the Bowser Basin the same magmatic and mineralizing events are recognized, forming an arch of gold andpolymetallic mineralization; known herein as the ‘Golden Horseshoe’

NW to NNW TRENDING FAULTS (Syn / Post-Min)
• Dominant structural features on property
• NW to NNW (310 + 340°) striking with subvertical or steep SW or NE dips
• Normal displacement; likely reactivated at some time (strike-slip)
• Oldest structures on the property representing syn-volcanic growth faults that formed during lower Jurassic extension and block faulting
• Act as conduits for later intermediate / mafic dykes
• Similar orientation as the CC-DR-PX and AGB hydrothermal systems (mineralized)
• Manifest as m-scale, sub-vertical fracture zones that are variably altered (silica +/- pyrite +/- sericite) and mineralized (low to high-grade min)

• Excellent correlation with mapped surficial structures• Faults acted as conduits for mineralizing fluids and therefore control the
mineralization• Mineralized zones occur in the hanging wall of the fault structures associated
with magnetic mediums• Numerous new targets identified for follow-up work and testing in 2020• Ground magnetic surveys are planned at several zones

Alteration
With proximity to mineralizedzones, a range of differentalteration assemblages arerecognized, from distal to proximal:
• Propylitic – epidote, chlorite
• Hematite – pervasive alteration and replacement of mafic minerals
• Potassic – fine-grained potassium feldspar as adularia ±sericite

In 2018 Benchmark completed a large airborne radiometric survey
• There is a very good correlation of elevated K/Th ratios (here shown
in red and pinks) to known areas of mineralization.
• The strong response is a result of the addition of potassium to the
volcanic host rocks as they were altered by the mineralizing fluids.
• 100% of known occurrences are associated with radiometric highs.
• Therefore, radiometrics is a very powerful targeting tool.Road Access to Kemess 45 km SE

Mineralization
Mineralization occurs in two discrete styles:
1. Phoenix-style mineralization is hosted within discrete quartz veins measuring approximately 1-8 metres wide. The veins contain semi-massive sulphides, including acanthite, sulfosalts, chalcopyrite, pyrite and native silver.
2. Broad zones of multiphase hydrothermal breccias composed of multi-generational chalcedony and quartz-hematite veining. The mineralized veins contain abundant fine to medium grained sulphides (acanthite, sulfosalts, chalcopyrite, and pyrite) and native gold, silver, and electrum.
2ND = Translucent grey quartz veins and stockwork silica flooding • mm to cm scale• mineralized, gold/silver sulfosalts (less so than 1)• hydrothermal breccia
3RD = Milky quartz open space filing veins • terminating crystals often amethyst• often crack and fill of type 1/2 veins, using the same plane of weakness
4TH = Breccia Veining - Hematite breccia• often associated with the zones of mineralization• not mineralized but contains clasts of mineralized 1/2 veins
5TH = Calcite veins, crack and fill, re-brecciation• reactivate mineralized veins/zones• often creating brecciated zones within the zones of mineralization • this could be space filling fluids in rubble zones from brecciated associated with earlier
events?• discrete calcite veins outside of mineralized zones suggest this event doesn’t have the
pressure to cause brecciation

?
Generalized cross section of the Toodoggone district (based on Diakow et al., 1993) showing location of the mineral deposits and prospect relative to the typical porphyry alteration zoning (based on Sillitoe, 2010), modified from MDRU/GBC 2019 Report.
The Mineral Deposits Research Group (MDRU) at the University of British Columbia is shedding light on the relationships between the porphyry and epithermal mineralization of the Toodoggone (link to report).
• They suggest historically mined and explored epithermal deposits are part of larger porphyry systems.
• This is based on a new exploration framework and geochemical index (MPIx) for defining porphyry potential.
• MDRU determined several low-sulphidation epithermal systems have numerous features that are indicative of the shallow parts of a porphyry system including the Cliff Creek zone on the Lawyers property.
• Ongoing work by Benchmark has identified an extensive (1.3 by 1.4 km) zone of clay alteration, known as the Silver Pond Zone.
• This may be the manifestation of a deeper high-sulphidation or porphyry environment
90% of the 140 km2 property is underexplored• Five resource expansion zones• Two new discovery zones for 2020 drill testing• Six early stage exploration targets for new discoveries
Previous mining overlooked the bulk-tonnage and porphyry potential• High-grade drill intercepts within wider mineralized envelopes • Open at depth - average drill hole under 100m• Copper porphyry targets associated with large zones of clay alteration,
soil and radiometric anomalies, and key stratigraphic horizons

Multiple Resource Zones for Expansion & Definition
Following the 2019 drilling program Benchmark has defined five discrete mineralized zones that will be the focus of resource definition and expansion drilling in 2020.
Up to 50,000 m of expansion and definition drilling will target all of these zones in 2020.
A global resource estimate will comprise one or more of Cliff Creek, Duke’s Ridge, Phoenix and AGB.
Six additional exploration targets across the 140 km2 property could provide additional ounces.

• The structure, mineralization, and alterationrelationships at the Marmot zones are consistentwith other zones on the Lawyers Trend, wherehydrothermal low-sulphidation systems developedwithin pre-existing fault systems that acted asconduits for fluids to migrate and precipitate.
• The relative geometry of these fault systemspossibly controls the distribution of high-grademineralization where faults of different orientationsintersect, as observed at both Marmot and MarmotEast.
• Ground geophysics, mapping, soil & rock sampling,and drilling are planned for the Marmot zones in2020.
