Mining & Processing
The FS contemplates Hod Maden as an underground mine divided into two distinct mining zones with a modified drift and fill (“DAF”) technique applied to the upper mine area and a long hole stoping (“LHS”) technique applied to the lower mine area. The bulk of the mineralization is located in the lower mine area, which will be accessed through a single portal north of the deposit. The upper mine will be accessed through two shallow shafts located north and south of the mineralization. The mine capacity is 800,000 tonnes per annum with a total of 8.7 million tonnes of ore produced during the 13-year mine life.
The ore to be processed is classified into two main categories: regular ore and a pyrite ore with a flowsheet reconfiguration when processing pyrite ore to maximize gold recovery. Ore processing contemplates a single stage crush, milling, a bulk flotation concentrate, regrind through a secondary milling and a secondary flotation, ultimately producing a saleable copper concentrate and a saleable pyrite concentrate. The concentrates will be transported to a port located on the Black Sea in Turkey for shipment to smelting facilities.
Infrastructure & Capital Costs
The majority of the proposed project infrastructure, including the process plant, paste plant, water treatment facility, transformer station and mining offices, will be located in the Maden Valley near the deposit. The tailings facility, mining waste dump, and quarry will be located to the north in the Salicor Valley. A tunnel will be constructed to connect the Maden Valley to the Salicor Valley. Grid power is available on site and some workforce can be based out of Artvin city nearby.

Proven & Probable 8,696 11.1 8.8 1.5% 3,114 2,452 287
CIM Definitions Standards (2014) were used in the preparation of the Mineral Reserve estimates.
The Mineral Reserve is estimated using metal prices of US$1,300 per oz Au and US$3.00 per lb Cu.
Effective Date of Mineral Reserve is 31 July 2020.
Errors in the totals are due to rounding.
Mineral Reserves are reported on the basis of mined ore to be delivered to the plant as mill feed.
The estimation was carried out using a breakeven cut-off value of USD82/t and incremental cut-of values of USD63/t for stopes and USD40/t for development.
The average mining recovery and dilution factors applied were 94% and 10% respectively.
Process recovery and payable factors averaged 85% and 98% respectively for gold and 93% and 95% respectively for copper.
Probable reserve gold grade and contained metal is higher than the indicated resource grade and contained metal due to the inclusion of measured resource from the modified DAF mining area above the 783m elevation.
Calculation of the gold equivalent grade (AuEq) is by the following formula: AuEq = [(Au Ounces + (Cu Pounds x 3/1300)) x 31.10348]/Tonnes

Sandstorm has included certain measures in this press release that do not have any standardized meaning prescribed by International Financial Reporting Standards (IFRS). With respect to the Hod Maden project, these measures include (i) all-in sustaining cost (“AISC”) per gold ounce on a co-product basis and AISC per gold ounce on a by-product basis, (ii) C1 costs on a by-product basis, and (iii) attributable gold equivalent ounce. As Sandstorm’s operations are primarily focused on precious metals, the Company presents these measures as it believes that certain investors use this information to evaluate the Company’s performance in comparison to other mining companies in the precious metals mining industry who present results on a similar basis. Other companies may calculate these measures differently as a result of differences in the underlying accounting principles, policies applied and in accounting frameworks, such as in IFRS. The presentation of these measures is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.
With respect to the Hod Maden project, AISC has been calculated on a co-product basis for gold and copper. The calculation for each metal is based on adding costs specific to each metal to costs allocated to each metal on a proportionate value basis. For gold, AISC per gold ounce on a co-product basis is calculated by summing certain costs (operating costs, royalties, treatment, refining & transport costs, sustaining capital depreciation, G&A, and other costs) associated with the gold produced. The resulting figure is then divided by the payable gold ounces produced. AISC per gold ounce on a by-product basis is calculated by deducting copper revenue from the summation of certain costs (operating costs, royalties, treatment, refining & transport costs, sustaining capital depreciation, G&A, and other costs). The resulting figure is then divided by the payable gold ounces produced.
AISC Co-Product Basis: [(Operating Costs ($543 million) + Royalties ($296 million) + Treatment, Refining and Transport Costs ($151 million) + Sustaining Capital Depreciation ($93 million) + G&A ($77 million) + Other Costs ($46 million)] / Payable Gold Ounces (2,027,000 oz) = $595 AISC per ounce].
AISC By-Product Basis: [(Operating Costs ($678 million) + Royalties ($349 million) + Treatment, Refining and Transport Costs ($193 million) + Sustaining Capital Depreciation ($116 million) + G&A ($96 million) + Other Costs ($57 million) - Copper Revenue ($812m)] / Payable Gold Ounces (2,027k oz) = $334 AISC per ounce].
With respect to the Hod Maden project, C1 Cash Cost on a by-product basis is calculated by deducting copper revenue from the summation of certain costs (operating costs, treatment, refining & transport costs, G&A, and other costs) associated with the gold produced. The resulting figure is then divided by the payable gold ounces produced.
The Company’s estimated royalty and other commodity stream income is converted to an attributable gold equivalent ounce basis by dividing the estimated royalty and other commodity stream income for the period by the estimated gold price per ounce for the same respective period. These attributable gold equivalent ounces when combined with the estimated gold ounces from the Company’s gold streams equal total attributable gold equivalent ounces and may be subject to change.
Numbers may not sum due to rounding.
