  FIGURE  1 (September 2, 2025 PR) - ASCU acquired 2,123 acres of private land  adjacent to the Cactus Project (see FIGURE 1), comprised of 2,043 acres  from a consortium of related private corporate landowners (collectively,  the “Consortium Land”) and completed on August 29, 2025, plus an  additional 80-acre parcel (the “80-acre Parcel”) acquired from a single  private corporate landowner on June 27, 2025. The Consortium Land  together with the 80-acre Parcel (collectively, the “Purchased Lands”)  are expected to provide the additional acreage necessary to support the  anticipated development and operations plan for the Cactus Project,  including the solvent extraction/electrowinning (“SX/EW”) plant  infrastructure, leach pads and waste rock stockpiles (collectively, the  “Project Plan”).
 
 CASA GRANDE, Ariz. & TORONTO--( BUSINESS WIRE)--Arizona Sonoran Copper Company Inc. (TSX:ASCU | OTCQX:ASCUF) (“ASCU” or the “Company”), an emerging US-based copper developer, acquired 2,123 acres of private land adjacent to the Cactus Project (see FIGURE 1), comprised of 2,043 acres from a consortium of related private corporate landowners (collectively, the “Consortium Land”) and completed on August 29, 2025, plus an additional 80-acre parcel (the “80-acre Parcel”)  acquired from a single private corporate landowner on June 27, 2025.  The Consortium Land together with the 80-acre Parcel (collectively, the “Purchased Lands”)  are expected to provide the additional acreage necessary to support the  anticipated development and operations plan for the Cactus Project,  including the solvent extraction/electrowinning (“SX/EW”) plant infrastructure, leach pads and waste rock stockpiles (collectively, the “Project Plan”). All dollar amounts are in U.S. currency unless specified otherwise.
 
 With  the addition of the Purchased Lands, contiguous to the Cactus Project  and of corresponding scale, we believe that all land requirements are  now in place to support the anticipated Project Plan.

 See below for a detailed summary of principal transaction terms for the Purchased Lands. Purchased Lands include all of the surface rights and all mineral rights held by the vendors   Cactus Project consolidated land package now encompasses 7,843 acres  expected to meet supporting land requirements for the anticipated Project Plan   the Purchased Lands provide operational flexibility to support potential  development of any incremental mineralization identified by future  exploration and/or existing primary sulphide mineralization at the  Cactus Project  
 Average purchase price of approximately $49,200 per acre  ~6% of aggregate purchase price paid on closing, partially with ASCU common shares   payment of balance deferred over next 4 years under vendor carry back  loans on favorable terms (collectively, as further described below, the “Vendor Loans”)  ~16% over next 3 years, with substantially equal amounts in each of 2026, 2027 and 2028, partially payable in ASCU common shares   remaining ~78% (plus accrued interest) due by August 29, 2029   unrestricted pre-payment rights with no penalty   average interest rate of 6% per annum, accruing and capitalized annually, and payable on maturity  
 Project financing, planned as early as Q4/2026, with the intention to pre-pay the consortium Vendor Loans in full prior to maturity  
 
 George Ogilvie, ASCU President and CEO, “During the ongoing  advancement of the pending Pre-Feasibility Study, it became evident that  while the necessary water and mineral rights were in place, once the  estimated mine life extended past year 15, additional acreage for  eventual surface operations would be needed. We foresaw this potential  and contemplated the acquisition of approximately 2,000 acres of  additional private land within the 2024 Preliminary Economic Assessment.  With the addition of the Purchased Lands, contiguous to the Cactus  Project and of corresponding scale, we believe that all land  requirements are now in place to support the anticipated Project Plan,  including a significant heap-leach and SX/EW copper cathode operation.  The acquisition of this land package consequently represents a major  de-risking event for the Cactus Project, as well as providing additional  real estate to potentially pursue development of the primary sulphide  deposits and future exploration opportunities, within the previously  held project properties. Additionally, the favorable structure, cost of  capital, pre-payment rights and other principal terms of these land  purchases, provide a financially manageable path forward for the Company  and the Cactus Project through the remaining studies to project  financing and an eventual final investment decision as early as Q4/2026.  With the completion of these acquisitions, the overall average  cost-per-acre of the Cactus Project private land package now stands at  approximately $23,000, quite favourable considering the extent of the  contiguous acreage of private lands acquired adjacent to the developing  Casa Grande industrial area, and which includes the Parks/Salyer and  Cactus deposits. This well-timed execution of the opportunity to  purchase a contiguous 2,123-acre land package from known, local private  property owners, is clearly a positive step forward for the Cactus  Project. We welcome the Consortium Vendors as new supportive  shareholders of the Company and as key stakeholders in the Cactus  Project.”
 
 PURCHASED LANDS
 
 Consortium Land
 
 On August 29, 2025, Cactus 110 LLC, an ASCU wholly-owned subsidiary (“Cactus 110”),  signed and closed a real estate purchase and sale agreement with a  consortium of related private corporate land owners (collectively, the “Consortium Vendors”) pursuant to which Cactus 110 purchased 2,043 acres (the “Consortium Transaction”).  The Consortium Land includes 100% of the surface rights to such lands  as well as all mineral rights held by the Consortium Vendors,  representing approximately 80% of the underlying mineral title. The  purchase price for the Consortium Land was $50,000 per acre (the  “Consortium Purchase Price”), with $5 million paid on the closing  ($2 million in cash and 1,549,487 common shares at a deemed price of  C$2.66 per share, representing $3 million value equivalent) and the  balance deferred subject to applicable Vendor Loans at an interest rate  of six percent (6%) per annum accruing and capitalized annually, and  payable on maturity in 2029, per the following schedule, with Cactus 110  having the right to pre-pay such loans, in whole or in part, at any  time, without penalty:
 
 
 
   | 2026 
 
 |  | $5 million (up to $3 million in ASCU common shares, at Cactus 110’s sole option) 
 
 |   | 2027 
 
 |  | $5 million (up to $2 million in ASCU common shares, at Cactus 110’s sole option) 
 
 |   | 2028 
 
 |  | $5 million (up to $2 million in ASCU common shares, at Cactus 110’s sole option) 
 
 |   | 2029 
 
 |  | subject any pre-payments, ~$82 million in deferred purchase price plus accrued, capitalized interest. 
 
 |  
 The Company anticipates having project financing for the Cactus Project  in place as early as Q4/2026, a portion of which could be used to  pre-pay the Consortium Vendors Loans, in full, in advance of maturity on  August 29, 2029.
 
 The number of ASCU common shares issued in each instance under the  Consortium Transaction, in lieu of cash at Cactus 110’s sole option,  will be determined using a 5-day volume weighted average trading price  of ASCU common shares on the TSX immediately preceding the applicable  payment due date, subject to customary TSX and other applicable  regulatory approvals, and a statutory hold period under applicable  securities laws. ASCU welcomes the Consortium Vendors as new  shareholders of the Company and key stakeholders in the Cactus Project.
 
 Each of the Consortium Vendor Loans are secured by deed of trust on  their respectively sold portions of the Consortium Land (and fixtures  thereon) and a deed of trust on the ~750 acre ARCUS lands already owned  by Cactus 110. In addition, one of the Consortium Vendors will hold  additional security for its Vendor Loan pursuant to a modified deed of  trust on 1,000 acres purchased by Cactus 110 in 2022 (see FIGURE 1) from that Consortium Vendor (the“2022 Seller”),  which remains subject to a final deferred purchase price payment of $5  million due, interest-free, by February 10, 2027 (the “2022 Property Loan”).  The Consortium Vendor Loans are subject to cross-default with one  another, and the 2022 Property Loan is subject to cross-default with the  Vendor Loan from the 2022 Seller. Payment defaults under the Consortium  Vendor Loans are subject to favourable cure periods of 30 days on the  2026, 2027, and 2028 payments and 90 days on the final payment due in  2029. A default on the final 2027 payment due under the 2022 Property  Loan is subject to a favourable cure period of 60 days.
 
 In addition to the Consortium Purchase Price, an aggregate 0.5% net smelter returns royalty (“NSR”)  on the Consortium Land was granted to a designee of the Consortium  Vendors, on terms consistent with other NSRs on the Cactus Project.  Cactus 110 has a right of first refusal on any sale, transfer,  assignment or other conveyance of the NSR by the Consortium Vendors’  designee, other than to an affiliate.
 
 Upon any transfer or sale, whether voluntarily or involuntarily,  directly or indirectly, of greater than fifty percent (50%) in Cactus  110 or the Cactus Project, prior to payment in full of the amounts due  and owing under the Consortium Vendor Loans, such  transferee(s)/purchaser(s) shall be required to acknowledge and affirm,  in writing, the binding nature of the continuing applicable terms of the  Consortium Transaction and the Consortium Vendor Loans.
 
 The Consortium Transaction and related Vendor Loans are otherwise  generally subject to customary terms and conditions for real estate  transactions in Arizona.
 
 80-acre Parcel
 
 On June 27, 2025, Cactus 110 completed the purchase of the 80-acre  Parcel, including 100% of the surface and underlying mineral rights,  pursuant to a real estate purchase and sale agreement with a private  corporate landowner (the “80-acre Vendor”) dated and effective as of April 29, 2025 (the “80-acre Purchase”). The 80-acrePurchase  price was $30,000 per acre, with $1.2 million paid in cash on closing,  with the remaining $1.2 million deferred subject to a  non-interest-bearing Vendor Loan, to be paid in full in cash by maturity  on June 27, 2026, with Cactus 110 having the right to pre-pay such  loan, in whole or in part, at any time, without penalty. The 80-acre  Vendor Loan is secured by deed of trust on the 80-acre Parcel (see FIGURE 1), under which Cactus 110 has up to 90 days to cure any payment or other default under the Vendor Loan. The 80-acrePurchase and related Vendor Loan is otherwise subject to customary terms and conditions for real estate transactions in Arizona.
