Nord Precious Metals Retains Engineering Support for Tailings
Reprocessing at Castle Mine Project
T Engineering is a Canadian engineering firm with an internationally proven track record
in tailings management, mineral processing, and complex recovery operations
Cobalt, Ontario – April 8, 2026 – Nord Precious Metals Mining Inc. (“Nord” or the “Company”)
(TSXV: NTH, OTCQB: CCWOF, FSE: QN3) has retained T Engineering Inc. (“T Engineering”), to
advance near -term silver recovery from tailings across the Company’s recently expanded
Gowganda-Castle district land package. The engag ement follows Nord’s completion, on March
31, 2026, of its acquisition of four mining leases in the Gowganda Silver Camp, which
consolidated the most productive ground in the historical district. With a regula tory fast -track
pathway for tailings recovery in Ontario, Nord is positioning to convert legacy resources into near-
term production.
Management Commentary
“The addition of the adjoining mining leases to the Castle Mine holdings is transformative for the
Company, adding key tailings deposits and underground infrastructure to our existing high-grade
silver position,” stated Frank J. Basa, P.Eng., President and CEO. “The Gowganda Camp
produced over 60 million ounces of silver before low prices shut it down. At today’s prices, the
district’s remaining resources represent a fundamentally different economic proposition, and
retaining T Engineering positions us to move forward on it.”
T Engineering Scope of Services
Services under the engagement include:
• Multidisciplinary engineering support across process, mechanical, civil, structural,
electrical, and automation disciplines, together with project management, procurement,
and financial analysis;
• Engagement of a third -party consultant, subject to Nord’s approval, to design tailings
storage infrastructure and provide geotechnical services; and
• Pilot-scale testing and process validation at T Engineering’s in -house laboratory in
Sudbury, Ontario, equipped for particle size distribution, rheology, thickening and filtration
testing, and other analytical work conducted to ASTM standards, to support scale-up and
optimize recovery performance for both gravity and hydrometallurgical circuits.
Consolidated District Highlights
• Historical Tailings Resource: The recently acquired Gowganda mining leases host a
historical resource estimate(1) of approximately 1,940,000 tonnes grading 47.5 g/t silver,
containing an estimated 2,960,000 ounces of silver.
• District-Scale Consolidation: The acquisition brings Nord’s total consolidated lease area
to 789.7 hectares, encompassing eight past -production shafts across the Gowganda -
Castle district. The acquired leases include three of the five largest past-producing mines
in the Gowganda Camp, including the Miller Lake-O’Brien complex, which alone produced
approximately 42 million ounces of silver (OGS R175, McIlwaine, 1978).
• Integrated Processing Infrastructure: The consolidated property includes historic mine
workings, surface infrastructure, and all -season road access, materially reducing
development risk.
• Critical Minerals Leverage: The district’s silver mineralization is complemented by
meaningful cobalt, copper, and nickel by -product potential. Silver, cobalt, copper, and
nickel are all designated critical minerals in Canada and/or the United States.
• Regulatory Pathway to Production: Ontario’s Recovery Permit framework provides a
fast-track regulatory pathway for tailings reprocessing, with advanced templates and
Ministry support already in place for Nord’s application. The Cobalt -Gowganda district
contains numerous orphaned tailings deposits from a century of mining; with TTL as the
only permitted processing facility in the district, Nord is positioned to convert these legacy
environmental liabilities into production feed. In addition, the Company’s ad vanced
exploration permit for the Castle Mine remains in place, permitting drilling and sampling
activities on the mine lease and supporting multiple concurrent development pathways
across the consolidated district. The Company maintains longstanding agree ments with
First Nations communities in the district, reflecting a commitment to responsible
development and local economic participation in recovery operations.
(1) The historical resource estimate for the Gowganda tailings is supported by a technical report
dated July 8, 2011, prepared in accordance with NI 43 -101, completed by GeoVector
Management Inc. for Temex Resources Corp. The report is authored by Joe Camp bell, P.Geo.,
Alan Sexton, P.Geo., M.Sc., and Allan Armitage, Ph.D., P.Geo. The historical estimate contained
in this news release has not been verified as a current mineral resource. A “qualified person” (as
defined in NI 43-101) has not done sufficient work to classify the historical estimate as a current
mineral resource, and the Company is not treating the historical estimate as a current mineral
resource. The Company considers the historical estimate to be relevant for the proper
understanding of the Project; however, significant data compilation, re -drilling, re-sampling, and
data verification may be required by a Qualified Person for the historical estimate to be in
accordance with NI 43 -101 standards and to verify the historical estimate as a current mineral
resource.
Qualified Person
The technical information in this news release was approved and prepared under the supervision
of Mr. Frank J. Basa, P.Eng. (PEO), director of Nord Precious Metals, a qualified person in
accordance with National Instrument 43-101.
About Nord Precious Metals Mining Inc.
Nord Precious Metals Mining Inc. operates TTL Laboratories, the only permitted high -grade
milling facility in the historic Cobalt Camp of Ontario, where the Company has established an
integrated position connecting high -grade silver discovery with strategi c metals recovery
operations.
The Company's flagship Castle property encompasses 56 sq. km of exploration ground and the
past-producing Castle Mine, complemented by the Castle East discovery where drilling has
delineated 7.56 million ounces of silver in a now historic, Inferred resource grading an average of
8,582 g/t Ag (250.2 oz/ton) in 27,400 tonnes of material from two sections (1A and 1B) of the
Castle East Robinson Zone, beginning at a vertical depth of approximately 400 metres. The
report, titled NI 43 -101 Technical Report Minera l Resource Estimate for Castle East, Robinson
Zone, Ontario Canada with effective date of May 28, 2020 authored by M.Rachidi, P.Geo., Ph.D.
of GoldMinds Geoservices. Mineral resources that are not mineral reserves do not have
demonstrated economic viability. Please refer to the Nord Precious Metals Press Release of May
27, 2020, for the resource estimate. The following notes were provided as part of the Resource
Estimate report: 1 - The database used for this mineral estimate includes drill results obtained
from historical (2011 one hole) to the recent 2019 drill program and wedges from the 2011
diamond drill hole; 2 - Mineral Resource is reported with mineable shape cut-off grade equivalent
to 125$USD (258 g/t AgEq) including mining, shipping and smelting cost with recovery of 95%.
The high -grade value of the mineral resources makes them direct shippi ng. Not all zones
(mineable shapes) are above economic cut-off grade and zone 02b is a must-take material. The
assay results are not capped as they are not considered as outliers at this stage and results are
reproducible; 3 - The minimum horizontal width of the mineralized envelopes includes dilution
and is 1.3m; and 4 - To convert volume to tonnage a specific gravity of 3.4 tonnes per cubic metre
was used. Results are presented in-situ without mining dilution.
The above resource is now considered an historical resource. This historical resource remains
relevant in that there is ongoing drilling to expand the known mineralization associated with that
resource. The 2020 mineral resource was estimated in conformity with CIM Estimation of Mineral
Resource and Mineral Reserves Best Practices Guidelines and is reported in accordance with
Canadian Securities Administrators’ NI -43-101. Insufficient work has been done since to
categorize the above historical estimate as current. Significant additional diamond drilling and
analytical work along with modelling is required before a new resource estimate can be compiled.
Nord’s integrated processing strategy enables multiple metal recovery streams. High-grade silver
recovery supports the economics of extracting critical minerals including cobalt, nickel, and other
strategic metals. The Re -2Ox hydrometallurgical process, va lidated at pilot scale through SGS
Lakefield, eliminates the typical arsenic barriers in complex silver -cobalt ores while producing
technical-grade cobalt sulphate and other metal products to customer specifications. This multi -
metal approach, combined wit h established infrastructure including TTL Laboratories and
underground mine access, positions Nord within Ontario’s emerging critical minerals supply chain.
The Company maintains a strategic portfolio of critical minerals properties in Northern Quebec
through its 35% ownership in Coniagas Battery Metals Inc. (TSXV: COS), as well as the St. Denis-
Sangster lithium project comprising 32 square kilometres of prosp ective ground near Cochrane,
Ontario.
