Pinargozu Zinc Mine
Summary
Pinargozu is located 28km north of Kozan, Türkiye in the eastern part of the Taurus mountain range. The mine is a 2-hour drive and 90 km northeast of the city of Adana (population 2.2 million). The mine is also a 2.5-hour drive from the Port of Mersin which connects the to the international commodities market.
Pasinex holds a 50% interest in the Pinargozu Operation Licence through Horzum Arama Isletme AS (Horzum AS), a 50/50 joint venture (JV) company between Pasinex Arama Madencilik AS (Pasinex AS), a wholly owned Turkish subsidiary of Pasinex, and Akmetal AS, the Turkish mining company that owns the nearby past producing Horzum zinc mine.
Pinargozu is a Carbonate Replacement Type zinc geological model. The Pinargozu carbonate replacement zinc project is similar to CRD deposits in Mexico such as Naica. The mine has been in production since 2014, producing both zinc oxides and zinc sulphides of DSO (direct shipping ore) grade material.
Until 2021 the mine production was primary zinc oxides. With a 4th adit completed at the 541 level the future of production will skew towards zinc sulphides. The average grade of the zinc sulphide product sold in Q3 2023 was 49%.

(1) See Non-GAAP Measures
- For the year ended December 31, 2023, Pasinex recorded a net loss of approximately $0.3 million, compared with a net income of approximately $2.04 million for 2022. The primary reason for the decrease in the net income into a net loss was the decrease in the equity gain in 2023 compared with 2022. In addition, the assigned dividend was lower in 2023. The decrease in net income was partially offset by lower exploration costs being incurred in Nevada in 2023 compared with 2022.
- The operating income in Horzum AS decreased in 2023, compared with 2022, as a result of the lower sales prices having been realized, fewer tonnes being sold, and higher costs being incurred. The results in 2022 were strong compared with prior years and the results in 2023 were comparable to 2021 and higher than 2020. The gross margin, (see non-GAAP measures), for the year ended December 31, 2023, decreased to 42% from 72% in 2022.
- Horzum AS declared a dividend to be paid to its shareholders of which Pasinex Arama was entitled to TRY 32.1 million (approximately $2.2 million using the exchange rate on the date the dividend was declared and approved). Pasinex Arama had received all of this amount by the end of 2023.
- Horzum AS had another zero-fatality year at the Pinargozu Mine with a total of 151,200 fatality free hours having been worked at the Pinargozu Mine in 2023. Horzum AS did report five serious injuries and 28 lost-time injuries during the year.
- Horzum AS mined 8,061 tonnes of zinc product during 2023, at the Pinargozu mine, compared with 13,766 tonnes of zinc product in 2022. Production at the Pinargozu Mine for 2023 fell short of the amount forecast at the beginning of the year. Production was negatively impacted, as Horzum AS effectively “lost” two months of production early in the year as a result of seconding some of its experienced miners and its mine rescue team to the earthquake recovery effort that badly impacted the province of Adana and Hatay in February and March of 2023.
- Sales volumes decreased for the year ended December 31, 2023, when compared with 2022. Total tonnes sold decreased to 7,979 in 2023 compared with 13,067 tonnes in 2022, representing an approximately 39% decrease. The decrease in tonnes sold was primarily a function of having lower zinc product available to sell during the year.
- Sales prices per tonne on a USD basis decreased by approximately 30% for zinc sulphide product for the year ended December 31, 2023, when compared to prices in 2022. There were no sales of zinc oxide product, low-grade zinc sulphide product or lead product in 2023. Total sales of all zinc product decreased to $8.4 million in 2023 compared with approximately $17.9 million in 2022, which translates into a 53.4% decrease in total revenue in 2023 compared to 2022.
- The average grade of the zinc sulphide product sold was 48.9% zinc per tonne for the year ended December 31, 2023, compared with 50.1% zinc per tonne in the same period in 2022. There were no sales of zinc oxide product, low-grade zinc sulphide product and lead product in 2023. In 2022, the average grade of sales of zinc oxide product was 37.8% per tonne, low-grade zinc sulphide product was 18.8% per tonne and lead product was 53.0% per tonne.
- The CAD cost per tonne mined (see non-GAAP measures) increased substantially in 2023, to $601 per tonne mined, compared with $380 per tonne mined in 2022. The cost per tonne metric was much higher in 2023 compared with 2022, in part due to far fewer tonnes being mined. However, the main reason for the substantial increase was the increase in the prices of supplies and services incurred in 2023, as a result of inflationary pressures experienced in Türkiye.
- The USD cash cost per pound of zinc product mined (see non-GAAP measures) increased to US$0.44 per pound in 2023 compared with US$0.28 per pound in 2022 primarily because of the increases in the costs of supplies and services incurred.
- The Joint Venture completed 10,782 metres of underground and surface diamond drilling in 2023 (9,345 metres in 2022) and completed 1,108 metres of exploration and development adit development during 2023 (1,743 metres in 2022).
- Subsequent to December 31, 2023, Pasinex Canada received approximately $380,000 from shareholders of the Company, which have been added to existing shareholder loan agreements. In addition, Pasinex Arama transferred US$60,000 (approximately $82,000 using the exchange rates on the dates of the transfers) to Pasinex Canada.

Horzum Joint Venture
In the province of Adana, south-central Türkiye, there is a 80 kilometre-long corridor between the historical Horzum zinc mine in the south and the historical Ak cal/Belbasi zinc mines near Tufanbeyli in the north. This area is underlain by a northeast-southwest trending belt of carbonate-dominated rocks, the Horzum Zinc Trend (HZT), known to host Carbonate Replacement-type zinc-lead deposits. There are several known historical small high-grade oxide zinc deposits in these rocks but the HZT had never been systematically explored using modern, advanced exploration techniques and models. The potential is strong for discovery of new much larger oxide and sulphide zinc deposits.
Recognizing this potential, Pasinex began acquiring exploration properties in 2012. Late in 2012 Pasinex, through its wholly owned Turkish subsidiary, Pasinex Arama ve Madencilik AS, formed the 50/50 Horzum AS joint venture (JV) with Akmetal AS, a large Turkish mining company and historical operator of the Horzum Zinc Mine. The JV combined the technical expertise of the Pasinex team and the mining infrastructure capabilities of Akmetal AS. Pasinex transferred its exploration properties into the joint venture.
The joint venture has a mandate to explore, develop and mine for zinc and lead mineralization in the provinces of Adana and Kayseri, Türkiye. The key focus area is the JV properties concentrated along the HZT extending at least 20 kilometres to the north of Horzum Mine.
The Akmetal-owned Horzum Mine produced approximately 1.0 million tonnes of zinc oxide ore grading 20% to 30% Zn from 1974 – 2000. From 1985 to 1997 it produced approximately 420,000 tons of sulphide ore. Ore was shipped to the Kayseri zinc smelter for processing. The Horzum property is not part of the JV but Pasinex controls a 5% interest in the property in exchange for providing exploration, geological and metallurgical consulting services to Akmetal for this project.
The JV acquired the Pinargozu property in 2013 from a private Turkish party for the sum of US$250,000. The Pinargozu license lies immediately to the north and east of the Horzum Mine on the HZT. The property is easily accessible by a gravel road connecting to Highway 815. In 2015, the JV made it a priority focus to develop the Pinargozu Mine in order to use cash flow from the sale of mined ore for development of the mine and exploration.
In 2012 the JV acquired the Akkaya property, located 1.5 kilometre north of Pinargzou Mine along the HZT. In 2015 additional properties were acquired along the HZT.
Geology
Türkiye’s geology is very complex and consists of several continental fragments (terranes) which were joined together into a single landmass in the late Tertiary. Türkiye is geologically divided into three main tectonic units: the Pontides, the Anatolides-Taurides and the Arabian Platform. Several thousand meters of shallow marine carbonates were deposited over the Anatolide-Tauride terrane during the Mesozoic. The terrane was intensely deformed, partly metamorphosed and intruded by calc-alkaline magmatism during the Late Cretaceous Alpide orogeny.
The project area straddles both the Bozkir and Geyik Dagi Units of the Central Tauride Belt portion of the Tauride-Anatolian Terrane. Post-Devonian-age strata overlie these two units in places. All three rock packages are known to host zinc mineralization.
The joint venture properties lie within the 80 kilometre-long corridor between the historical Horzum zinc mine in the south and the historical Ak cal/Belbasi zinc mines near Tufanbeyli in the north. It is underlain by a northeast-southwest trending belt of carbonate-dominated rocks which range in age from Cambrian to Upper Cretaceous. These limestones host reef breccias (which control zinc deposition near Tufanbeyli) and are subject to faults and fractures, dissolution collapse breccias, and lithological transitions (which control zinc deposition at Horzum). These limestones are primary targets for Carbonate Replacement-type zinc-lead deposits.
Carbonate Replacement Deposits (CRD) are orebodies of metallic minerals formed by the replacement of sedimentary, usually carbonate, rock by hydrothermal metal-bearing solutions in the vicinity of igneous intrusions. The mineralogy changes with distance from the intrusive rock. Closest to the intrusion is the copper-gold zone; next is the lead-silver zone, then the zinc-manganese zone. Typically CRD deposits are much younger than their host carbonates. This is in contrast to Mississippi Valley Type (MVT) deposits typically occurring along passive tectonic margins where the ages of the mineralization and the host carbonate are very similar and the ore fluids are typically low temperature (100 °C-150 °C) and have the composition of basinal brines.
The shapes of CRD deposits are often strongly controlled by faults and fractures in the rocks through which the mineralizing fluids flowed resulting in deposit shapes including “chimneys” for deposits with vertical dispositions, and “mantos” for deposits with horizontal, blanket-like orientations. Chimney deposits are often formed closer to their igneous source while manto deposits often occur further away and are defined by a strict stratigraphic control on their distribution, generally within a porous formation within a structural trap site. The igneous link to manto deposit formation is usually not conclusively proven. CRD deposits are notoriously difficult to explore for as there is a sharp contact between high grade mineralization and barren host carbonate rock. Limestone just inches from the mineralization can appear fresh with no alteration or geochemical signature.
Geochemical characteristics of the Horzum and Pinargozu deposit strongly suggest that they are CRD deposits, rather than MVT. It is thought that Pinargozu is at the oxidized manto “top” of what they conjecture could be a larger CRD orebody at depth (see figure below).
Skarn deposits are formed by direct reaction of intrusive rocks with carbonates and occur in contact with or within the igneous intrusions. No intrusive rocks have been mapped in the JV area to date. However the possibility exists for igneous bodies and skarn deposits at depth.
