Sierra Metals Announces Drill Results from its Bolivar Mine in Mexico
Sierra Metals (SMTSF) has announced promising drill results from its Bolivar Mine in Mexico, specifically from the Marian Zone. The drilling program revealed copper grades higher than current Measured & Indicated Mineral Resources, with potential to extend the mineralized body by approximately 300 meters along strike and 600 meters vertically.
Notable drill intercepts include grades up to 2.45% copper, with varying gold, silver, and zinc content. The Marian Zone is characterized as a mineralized ore body trending northeast-southwest with a 67° southeast dip, located northwest of the Cieneguita Manto Zone. The mineralization width varies between 9 and 26.4 meters.
Additional drilling is planned for 2025 to further extend the Marian Zone to the northeast and at depth. The company views these results as part of their strategic exploration efforts to replace and grow mineral resources at Bolivar.
Sierra Metals (SMTSF) ha annunciato risultati promettenti di perforazione dalla sua Miniera Bolivar in Messico, specificamente dalla Zona Marian. Il programma di perforazione ha rivelato leghe di rame superiori a quelle attualmente misurate e indicate nelle risorse minerali, con la potenziale estensione del corpo mineralizzato di circa 300 metri lungo la direzione e 600 metri in verticale.
Le interceptazioni di perforazione notevoli includono leghe fino al 2.45% di rame, con contenuti variabili di oro, argento e zinco. La Zona Marian è caratterizzata come un corpo minerale tendenziale nordest-sudovest con una pendenza di 67° a sudest, situata a nordovest della Zona Manto Cieneguita. La larghezza della mineralizzazione varia tra 9 e 26.4 metri.
Ulteriori perforazioni sono programmate per il 2025 per estendere ulteriormente la Zona Marian verso nord-est e in profondità. L'azienda considera questi risultati parte dei suoi sforzi strategici di esplorazione per sostituire e accrescere le risorse minerali a Bolivar.

시에라 메탈스 (SMTSF)는 멕시코의 볼리바르 광산에서 마리안 구역의 유망한 드릴 결과를 발표했습니다. 드릴링 프로그램은 현재 측정 및 표시된 광물 자원보다 높은 구리 등급을 나타냈으며, 약 300미터의 길이와 600미터의 깊이에 걸쳐 광화체를 연장할 가능성을 보여주었습니다.
주목할 만한 드릴 탐지는 최대 2.45%의 구리를 포함하며, 다양한 금, 은, 아연 함량이 있습니다. 마리안 구역은 북동-남서 방향으로 경향을 보이며, 67°의 남동 경사를 가진 광물화된 광체로, 시에네기타 만토 구역의 북서쪽에 위치해 있습니다. 광물화 폭은 9미터에서 26.4미터 사이로 다양합니다.
추가적인 드릴링이 2025년으로 계획되어 있으며, 마리안 구역을 북동쪽으로 및 깊이로 확장할 예정입니다. 회사는 이러한 결과를 볼리바르에서 광물 자원을 대체하고 성장시키기 위한 전략적 탐사의 일환으로 보고 있습니다.
Sierra Metals (SMTSF) a annoncé des résultats de forage prometteurs de sa mine de Bolivar au Mexique, spécifiquement de la zone Marian. Le programme de forage a révélé des taux de cuivre supérieurs aux ressources minérales mesurées et indiquées actuelles, avec un potentiel d'extension du corps minéralisé d'environ 300 mètres le long de la direction et de 600 mètres en profondeur.
Les intercepts de forage notables incluent des taux allant jusqu'à 2,45 % de cuivre, avec un contenu variable en or, argent et zinc. La zone Marian est caractérisée comme un corps minéralisé s'étendant du nord-est au sud-ouest avec une pente de 67° au sud-est, située au nord-ouest de la zone Manto de Cieneguita. La largeur de la minéralisation varie entre 9 et 26,4 mètres.
D'autres forages sont prévus pour 2025 afin d'étendre davantage la zone Marian vers le nord-est et en profondeur. L'entreprise considère ces résultats comme faisant partie de ses efforts stratégiques d'exploration pour remplacer et accroître les ressources minérales à Bolivar.
Sierra Metals (SMTSF) hat vielversprechende Bohrergebnisse aus seiner Bolivar Mine in Mexiko, insbesondere aus der Marian Zone, bekannt gegeben. Das Bohrprogramm ergab Kupfergehalte, die höher sind als die derzeit gemessenen und angegebenen Mineralressourcen, mit dem Potenzial, den mineralisierten Körper um etwa 300 Meter entlang des Streiks und 600 Meter in der Tiefe zu erweitern.
Bemerkenswerte Bohrabschnitte umfassen Gehalte von bis zu 2,45% Kupfer, mit variierendem Gold-, Silber- und Zinkgehalt. Die Marian Zone wird als ein mineralisierter Erz Körper beschrieben, der nordost-südwestlich geneigt ist und einen 67° Hang zur Südostseite aufweist, der nordwestlich der Cieneguita Manto Zone liegt. Die Mineralisationsbreite variiert zwischen 9 und 26,4 Metern.
Zusätzliche Bohrungen sind für 2025 geplant, um die Marian Zone weiter nordöstlich und in der Tiefe zu erweitern. Das Unternehmen sieht diese Ergebnisse als Teil seiner strategischen Erkundungsbemühungen, um mineralische Ressourcen in Bolivar zu ersetzen und zu vergrößern.
- Drill results show higher copper grades than current Measured & Indicated Resources
- Mineralized body potential extension of ~300m along strike and ~600m vertically
- Notable high-grade intercepts up to 2.45% copper
- None.
- Copper grades from the drill results are higher than the ones reported in the current Measured & Indicated Mineral Resource for the Bolivar Mine.
- These results underscore the Bolivar Mine’s potential for further resource growth and enhanced value creation for stakeholders.

These recent drill results have the potential to increase the Mine’s current mineral resource as set out in the Company’s National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) compliant report entitled “Technical Report on the Bolivar Mine” dated June 14, 2024 (the “Bolivar Technical Report”). By including these new drill holes, the dimensions of the mineralized body have the potential to extend by up to an additional ~300 meters (“m”) along strike and by ~600 m vertically. Additional drilling is planned in 2025 to continue to extend the Marian Zone to the northeast and at depth.
Ernesto Balarezo, Sierra Metals CEO, comments, “We are very pleased with the results of our exploration strategy at Bolivar to date and these results only offer what we believe is a glimpse of the mine’s full potential. This drill program in the Marian Zone indicates higher metals grades that have the potential to add to the overall mineral resources at Bolivar. These significant drill results from the Marian Zone reflect the continuous success of our targeted exploration strategy and highlight the untapped potential of the Bolivar Mine. Exploration and drilling, both to replace and continuously grow the mineral resources, are an important part of Sierra’s strategy.”

Marian is a mineralized ore body or “feeder zone” that trends in a northeast – southwest direction with a 67° dip to the southeast. It is located northwest of the Cieneguita Manto Zone, cutting carbonate rocks previously affected by calc-silicate metasomatism. The width of mineralization varies between 9 m and 26.4 m, with copper grades directly correlated to the presence of chalcopyrite, lesser bornite, and pyrite. Drill hole DB24BM958, at elevation of 1,200 m, is the deepest, and shows the potential of going additional 600 m at depth with the structure open laterally and vertically (Figure 2).
