Akiba Leisman, CEO of Mako states: "the Moss mineral reserve declaration and updated project economics is an important milestone for Mako. While the Company began mining operations at San Albino over 6 years ago, and mining at Moss 12 months ago, these are the first mineral reserves the Company has declared. Going forward, this will unlock opportunities to lower our cost of capital, as the Company's lack of mineral reserves has previously been a constraint. Mako acquired Moss in March of 2025 for a net purchase price of approximately US$2 million. Multiples of the acquisition price have already been returned to the Company through cash flow, and management believes that the economics reported today, based on real operating economics from the mine, reflect one of the highest return on invested capital acquisitions made during this commodity cycle. Over the course of this quarter, Mako will announce additional opportunities to lower the cost of its capital so that we can continue to make highly accretive acquisitions in the future."

Notes for Tables 4 & 5:
- Numbers have been rounded to reflect the precision of a Mineral Resource Estimate. Totals may vary due to rounding.
- Mineral Resource Estimates conform to NI 43-101, and the 2019 CIM Estimation of Mineral Resources & Mineral Reserves Best Practice Guidelines and 2014 CIM Definition Standards for Mineral Resources & Mineral Reserves.
- AuEq is calculated using a silver-to-gold ratio of 194.6:1, derived from assumed metal prices (US$2,500/oz Au and US$29.20/oz Ag) and assumed metallurgical recoveries (75% for Au) and 33% for Ag).
- Mineral Resources are constrained within an optimized open-pit shell using a 0.17 g/t AuEq cut-off grade. Pit optimization assumptions include US$2,500/oz gold, US$29.20/oz silver, 75% gold recovery, and 33% silver recovery.
- Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability. The quantity and grade of reported Inferred Resources in this Mineral Resource Estimate are uncertain in nature and there has been insufficient exploration to define these Inferred Resources as Indicated or Measured Resources, however, it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
- The Company is not aware of any environmental, permitting, legal, title, taxation, socio-economic, marketing or political factors that might materially affect these Mineral Resource Estimates.

Production Profile and Reserve Development Strategy
The table below provides a summary of production over the estimated 15-year LOM;
Production summary table
| Category | Value |
| Mine Life | 15 years |
| Average annual recovered Au | 30,928 oz |
| Peak recovered Au | 46,137 oz |
| Total recovered Au | 442,904 oz |
| Average annual recovered Ag | 143,408 oz |
| Total recovered Ag | 2,081,565 oz |
| Average ore throughput | 12,049 tons/d |
| Peak ore throughput | 14,000 tons/d |
The Mineral Reserve mine plan reflects a staged development profile. Current mining activities are focused on the initial phases of the Reynolds and Central pits, which contain lower than average grades relative to the 15 year LOM plan. Pre-stripping activities have commenced at the East and North pits with LOM average grades expected by January 2027.
The mine plan incorporates a phased expansion of mining and processing capacity designed to maximize the value of the Mineral Reserve. After final 2026 plant debottlenecking exercises are complete, the plant is expected to produce approximately 3.3 million tonnes per year (3.5 million short tons per year) from 2027 to 2030, corresponding to a nominal processing capacity of approximately 8,200 tonnes per day (9,000 short tons per day). A second planned expansion increases nominal processing capacity to approximately 12,700 tonnes per day (14,000 short tons per day) beginning in 2031, with this capacity maintained through most of the remaining LOM.
A key driver of the improved production profile is the scheduled transition to mining the East Pit. Early production is sourced predominantly from the Reynolds and Central pits, where mineral reserve grades generally range from approximately 0.27 to 0.31 g/t Au (0.008 to 0.009 oz/short ton Au). East Pit Phase 1 contributes higher-grade ore for processing, averaging approximately 0.48 g/t Au (0.014 oz/short ton Au), with localized mineral reserve grades of up to approximately 0.65 g/t Au (0.019 oz/short ton Au). The introduction of this higher-grade material improves the average processing feed grade during the middle years of the LOM and supports increased gold production.
The higher mineral reserve grades in the East Pit reflect differences in the style and distribution of gold mineralization recognized in the current geological model. Mineralization east of the north-northwest-trending Canyon Fault is interpreted to be hosted predominantly within well-developed epithermal quartz vein systems characterized by greater vein continuity and higher gold grades. In contrast, mineralization west of the Canyon Fault, which includes the Reynolds and Central pits, is hosted primarily within broad zones of diffuse, fine-grained quartz stockwork and veinlets that generally exhibit lower average gold grades. These contrasting mineralization styles result in a higher average reserve grade within the East Pit and are an important factor underlying the improved production profile as mining progresses eastward.
The combined effects of increased processing capacity and higher reserve grades are reflected in the recovered gold production profile. Annual recovered gold production increases from approximately 18,000 to 24,000 ounces during the initial years of production to approximately 33,600 ounces in 2030 as higher-grade East Pit ore contributes a higher proportion of plant feed. Following the expansion to approximately 12,700 tonnes per day (14,000 short tons per day), annual recovered gold production increases to approximately 47,100 ounces in 2031 and remains robust throughout the balance of the LOM, generally ranging between 27,000 and 43,000 recovered ounces per year. Over the LOM, the Mineral Reserve is expected to produce approximately 442,904 recovered ounces of gold.
The increase in recovered gold production is supported by both improved mineral reserve grades and increased processing throughput. While annual contained gold varies with the mining sequence and mineral reserve grade, recovered gold production reflects the application of the metallurgical recovery assumptions incorporated into the mineral reserve estimate and therefore provides the appropriate basis for evaluating expected operating performance.
Exploration Upside
Beyond the current mineral reserve, the project hosts additional Inferred Mineral Resources, representing a meaningful near-term exploration opportunity. Importantly, exploration to date has been concentrated along the Moss and Ruth vein systems, which occupy only a small portion of Mako's approximately 16,900-hectare (41,760-acre) land package. The vast majority of the property remains untested despite the presence of numerous prospective structural and geochemical targets identified through surface prospecting. To accelerate target generation, the Company is currently completing a property-wide hyperspectral survey that will help prioritize drill targets across the broader concession package, underscoring the significant exploration potential beyond the known deposits.
Note: Inferred Mineral Resources are considered too speculative geologically to have economic considerations applied that would enable them to be categorized as Mineral Reserves, and there is no certainty that Inferred Mineral Resources will be converted to Measured or Indicated Resources or Mineral Reserves.
Corporate Update
A royalty litigation settlement has been reached with Patriot Gold Corp. ("Patriot") with respect to its 3% royalty interest on Moss. Mako has paid all accrued royalties to Patriot since Moss was acquired by an affiliate of Mako on December 31st, 2024 and will pay Patriot an additional US$1.55 million of the remaining ~US$3.7 million controlled by the bankruptcy monitor pending approval by the Arizona Court. All royalties due to Patriot have been accrued since Mako and affiliates acquired Moss, and management believes the remaining collateral held by the bankruptcy monitor, which Mako has a priority interest in, will be in excess of its current carrying value on Mako's balance sheet. Mako was unsuccessful in discharging this royalty last year (see press release dated November 20th, 2025) and is glad that this matter is resolved. Litigation with affiliates of Royal Gold Inc. continues with respect to their (up to 1%) royalty on a portion of the Moss property.
