Vancouver, British Columbia, March 02, 2026—Doubleview Gold Corp (TSX-V: DBG / OTCQB: DBLVF
/ GERMANY: 1D4) ("Doubleview" or the “Company”) is pleased to announce the results of its
Preliminary Economic Assessment (PEA) of its 100%-owned polymetallic Hat porphyry project (“Hat”
or “the Project” ), in northwestern British Columbia. With major content of copper, gold, cobalt ,
silver, and scandium, Hat becomes an important source of critical minerals.
Three processing scenarios were evaluated —Scenario A1 (A1) a Cu –Au-Ag-Co flotation base case
using current testwork recoveries1, Scenario A2 (A2), the same base case using expected recoveries1,
and Scenario B (B), a Cu–Au-Ag-Co flowsheet with an added hydrometallurgical circuit and scandium
recovery circuit —with results indicating the Project is financially attractive even without the
scandium component.
Highlights:
• Robust Project Economics: The PEA demonstrates a high -margin operation with an After -
Tax NPV(5%) of C$4.96 billion (A1), C$6.73 billion (A2), or C$6.94 billion (B), and an IRR of
19% (A1), 23% (A2), or 19% (B) at analyst consensus metal prices 2. Using a spot -price
scenario3, the Project delivers a compelling after-tax NPV(5%) of C$11.05 billion (A1), 13.53
billion (A2), or C$14.52 billion (B) and an IRR of 34% (A1), 39% (A2), or 32% (B).
• Sensitivity Highlight: Project economics show the greatest leverage to overall metal prices,
with NPV (5%) ranging from C$3.2 billion to C$10.2 billion (IRR: 14%–32%) at ±20% on all
metals; even under additional +20% CAPEX and +20% OPEX sensitivities, applied on top of
a 25% contingency already embedded in the base case, all scenarios deliver IRRs of 16% or

better, and Scenario B provides additional scandium oxide upside with NPV (5%) of C$6.2
billion–C$7.7 billion (IRR: 18%–20%) at ±40% metal price.
• Tier 1 Scale and Longevity: The mine plan supports a multi -decade life of 25 years at a
120,000 tonnes -per-day processing rate, underpinned by a resource base of 609 Mt at
0.43% CuEq4 in the Measured and Indicated categories and 503 Mt at 0.41% CuEq 4 in the
Inferred category.
• High-Output Production Profile B: Envisioned as a conventional large -scale open -pit
operation, the Project is expected to produce an average of over 74 kt of copper, 254 koz
of gold, 376 koz of silver and 2.7 kt of cobalt annually during the first 10 years, with life-of-
mine (LOM) average production of 67.6 kt Cu, 217 koz Au, 348 koz Ag, 2.5 kt Co, and 128
tonnes of scandium oxide per year. (NOTE: projected cobalt to be about 68% of North
America’s cobalt production based on 2024 production)
• Strategic Importance for Critical Minerals: The Project is positioned as a primary North
American source of copper, scandium, and cobalt. With approximately 2.42 billion pounds
of copper, 80 million pounds of cobalt and 2,415 tonnes of scandium oxide contained 5 in
the Measured and Indicated categories, the Project represents an important discovery of
critical minerals.
• Stable, Supportive Jurisdiction: Located in a premier mining district in British Columbia, the
Project benefits from a stable regulatory environment. The Company is committed to
engaging with local First Nations in a respectful manner and to working toward positive and
constructive relationships as the Project advances.
• Catalyst for Development: The PEA serves as the technical foundation for an immediate
transition into a Pre-Feasibility Study (PFS), providing a clear roadmap for early works and
permitting activities in 2026 and 2027.
Farshad Shirvani, President and CEO of Doubleview Gold Corp., commented, “The results of this PEA
confirm the scale, strength and long-term potential of the Hat Project. Delivering a post-tax NPV(5%)
of up to C$6.94 billion and IRR of up to 23% at consensus prices, and even stronger metrics at spot
prices, validates years of disciplined exploration and technical work by our team. Hat is
demonstrating Tier 1 characteristics with a 25-year mine life, strong annual production profile and
meaningful free cash flow generation. Importantly, the Project stands on its own without reliance
on scandium, while still preserving significant upside from critical minerals as markets mature. We
are excited to advance Hat to Pre-Feasibility and continue building a major Canadian critical metals
project.”
Doubleview acknowledges that the Project is located on the traditional territories of the Tahltan
Nation and the Taku River Tlingit First Nation, and recognizes their enduring relationship to and
stewardship of the land and waters. Doubleview is committed to respectful, transparent, and
ongoing engagement with First Nations and local communities whose territories overlap the Project
area and access rou tes, with a focus on protecting water and the environment and advancing
responsible development.

PEA OVERVIEW
The PEA contemplates a conventional open-pit mine and processing operation with a 25-year mine
life at a 120,000 t/d (42 Mt/a) plant throughput. Two processing pathways were evaluated, A1 and
its alternative, A2, and B: the first alternative, A, is a Cu–Au–Ag–Co flotation concentrator with two
recovery cases based on current metallurgical testwork , and A2, reflecting expected performance
(Figure 1); and B , a full circuit that retains the base flowsheet and adds a downstream
hydrometallurgical scandium recovery circuit (Figure 2).
The tailings storage facility is a centreline-raised facility built with compacted cycloned sand from
tailings underflow , and engineered drainage for stability, with site -contact waters (including
seepage and pit dewatering) recycled to the process plant and final closure involving pond drainage
and reclamation. The Project is expected to rely on grid power via an extended transmission line.
Tables 1 to 3 summarize the key results of the PEA, including production, operating costs, capital
expenditures, and the principal financial metrics; the sections that follow provide additional detail

Notes:
1 Scandium tonnages represent 12.5% of the mineralized material by category, reflecting the proportion of tailings
expected to be processed through a dedicated scandium leach circuit under current metallurgical design constraints.
2 Scandium oxide metal content have been calculated using the metallurgical recovery of 72% and conversion factor
from Sc to Sc2O3 of 1.534.
• Mineit’s Qualified Person, Tomasz Wawruch, FAusIMM, completed the MRE, and has reviewed and approved the
technical disclosure related to the MRE contained in this news release. Mr. Wawruch is a senior geology and
mineral resource consultant independent of Doubleview. Mr. Gilles Arseneau, PhD., P.Geo., of ARSENEAU
Consulting Services Inc., provided an independent review of this MRE.
• Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
• The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation,
socio-political, marketing, or other relevant issues.
• Inferred Mineral Resources are considered too speculative geologically to have economic considerations applied
to them that would enable them to be categorized as Mineral Reserves.
• The Mineral Resource Estimate was prepared in accordance with the Canadian Institute of Mining, Metallurgy
and Petroleum (CIM) Definition Standards for Mineral Resources and Mineral Reserves (2014), and CIM MRMR
Best Practice Guidelines (2019).
• The effective date of the MRE is February 4, 2026.
• Metal contents have been calculated using the following metallurgical recovery factors: Cu = 85%, Au = 89%,
Co = 78%, and Ag = 68%.
• Economic assumptions used include US4.80/lb Cu, US20.00/lb Co, US3,200/oz Au, US46/oz Ag, and a 2% NSR
royalty.
• Mineral Resources are reported within optimized open pit constraints and 0.2% CuEq cut-off grade, based on a
C7.93/t milled processing cost and C2.90/t milled general and administrative cost, with a mining cost of C3.01/t
plus incremental mining cost increasing by C0.015/t for every bench below the reference level of 1,125 mRL.

• CuEq calculations do not include scandium. The formula used to calculate CuEq is:
CuEq = [(((Ag × 46.0 × 0.68)/31.1035) + ((Au × 3200 × 0.89)/31.1035) + 0.0001 × (Co × 20.0 × 0.78 × 22.0462) + 0.0
001 × (Cu × 4.8 × 22.0462 × 0.85))/(4.8 × 22.0462 × 0.85)], where all input variables are expressed in (ppm) and
CuEq is expressed in percent (%).
• Rounding may result in minor variations between individual values and totals; such differences are not considered
material to the MRE.
• Mineral Resource classification reflects the level of geological confidence and satisfies the uncertainty criteria
appropriate for exploration and resource development. Additional drilling will be required to reduce uncertainty
to the level expected for production planning.
• The MRE reflects the geological interpretation, drill-hole spacing, and estimation parameters available at the time
of modelling. Any additional drilling is expected to influence the current outcome by improving confidence in the
estimates and refining the geometry of the mineralized domains.
• The Mineral Resource results are presented in situ within the optimized pit. Mineralized material outside the pit
has not been considered as a part of the current MRE tabulation. Calculations used metric units (metres, tonnes,
g/t).
• A total of 97 diamond drill holes, comprising 49,548 m of core, were incorporated into the Mineral Resource
Estimate. All drilling data used in the MRE were subject to standard QA/QC validation prior to inclusion.
PROCESSING SCENARIOS
The PEA evaluates two processing scenarios: (A) a conventional Cu –Au–Ag–Co flotation
concentrator at 120,000 t/d (42 Mt/a) with two recovery cases—A1 based on metallurgical testwork
completed by Sepro Laboratories (Langley, BC) and A2 reflecting target/exp ected performance—
and (B) a full circuit that retains the base flowsheet and adds a downstream hydrometallurgical
scandium recovery circuit.
The concentrator consists of crushing, grinding, flotation, concentrate handling, and tailings
management, producing both a saleable approximately 25% Cu concentrate with co -product gold
and by-product silver-cobalt credits and a pyrite concentrate enriche d in cobalt; in the full -circuit
case, the pyrite concentrate is roasted to generate sulphuric acid and a calcine that is then processed
to recover cobalt, gold, silver, and copper; after stripping it will be precipitated as a sulphide to be
admixed to the copper concentrate to improve grade, with the acid used to leach flotation tailings
for scandium recovery, noting that the scandium circuit is a newer chemical process compared with
the otherwise industry-standard flowsheet.
Under A1 or A2 (Figure 1), the flowsheet produces a single saleable product—a copper concentrate
with payable gold credits; the pyrite concentrate is not treated or marketed in this case and is only
processed in B where the hydrometallurgical circuit enables recovery of cobalt (and additional Au–
Ag) and supports the scandium circuit (Figure 2), which is planned to be constructed in a phased
approach commencing in Year 3 of operations.
