VANCOUVER, BC / ACCESSWIRE / April 13, 2023 / Hannan Metals Limited ("Hannan" or the "Company") (TSXV:HAN)(OTC PINK:HANNF) is pleased to announce that drilling has commenced at the Kilmurry zinc-silver-lead target in Ireland directly targeting a seismic anomaly interpreted to represent massive sulphides at 700 m vertical depth.
Highlights:
- Drilling to target a high amplitude seismic reflector, interpreted to represent massive sulphides has been permitted and drilling of hole 23-3643-19 has commenced at Kilmurry, Ireland (Figure 1).
- The seismic reflector was identified in line 17-HAN-02, acquired by Hannan in 2018. The target extends over 1 km strike with the highest amplitudes focused in a 400 m wide zone at 700 m depth (Figure 2).
- The target is located within the Kilmurry Fault system (reported by the Company in 2019). It represents a syn-sedimentary ramp relay fault system which exceeds over 15 km in length and is up to 2 km wide, with over 700 m vertical displacement. This represents one of the largest basin-scale displacements mapped in Ireland (Figure 2) and forms a compelling large-scale target, with historic results interpreted to be the distal parts of a major mineralizing system. This is supported by:
- Drill hole 11-3643-10, located approximately 900 m south, intersected extremely high grades of mineralization (0.3 m @ 56.5% zinc ("Zn") plus lead ("Pb")) at 166 m depth, in the hanging wall to the Waulsortian mineralized position.
- Historic work in the footwall of the ramp relay fault system, some 2.5 km south of the ongoing drill hole, mapped an extensive zone of dissolution and black matrix breccias as well as low grade zinc-lead mineralization such as 2 m @ 5.1% Zn+Pb and 2 m @ 5.8% Zn+Pb (Figure 2).
Michael Hudson, Chairman & CEO, states: "While awaiting drill permits on our vast and extensive Peruvian and Chilean copper targets, we look forward to drill testing what we believe to be one of the best grassroots zinc-silver-lead exploration targets developed in Ireland over the last decades. The target represents a rare opportunity in Europe's premier zinc province to leverage the benefit of our past application of seismic technology in hard rock exploration. This has allowed us to both constrain the geological model and drill test a high amplitude seismic anomaly, which is interpreted to be massive sulfides at 700 m depth. Drill testing has started and will be completed by the end of May.
"Meanwhile, final drill permitting on our copper-silver JOGMEC joint venture in San Martin, Peru is expected over the next quarter. Additionally, our drill permit process is advancing at our Valiente copper-gold porphyry projects in Peru where a team of 12 people have recently completed the baseline environmental survey. In Chile, geophysical ground crews will mobilise in the coming weeks to validate historic magnetic and electro-magnetic anomalies over the Cerro Rolando porphyry copper target to define drill targets. Should these surveys be successful, it is anticipated drilling permissions should take 3-4 months in Chile.
With all these current and upcoming drill programs, Hannan has developed a series of concurrent drill tests of large-scale critical metal projects, starting today and extending over the coming years. We do not see the drill rigs stopping for long and look forward to providing investors with exposure to potential new and large scale, potential company-making grassroot discoveries."
GEOLOGICAL DISCUSSION
The Kilmurry syn-sedimentary relay fault system represents an unexplored ramp-relay fault system for Irish style carbonate replacements deposits. This deposit style exhibits both strong structural and stratigraphic controls. The fault system is rare in the sense that it has been de-risked by seismic mapping, which has constrained both the geological model and the drill depth of the target. The survey deployed by Hannan in 2018 also identified a unit of high seismic impedance which subsequently has been interpreted to potentially represent massive zinc-silver-lead sulphides (Figure 2). The size of this impedance anomaly is up to 1,000 m wide and with the highest amplitudes focused over a 400 m window.
Historic work at Kilmurry by Lundin Mining, predating Hannan's exploration, focused on the footwall of the fault system prior to the context that the seismic surveying provided. The results strongly suggested the presence of an active mineralizing system in the area. This is exemplified by the dissolution breccias in various drill holes and low-grade base metal mineralization up to 2 m @ 5.8 % Zn+Pb. The seismic survey suggested the best part of the fault system (the hanging wall), was poorly drill tested, with only one drill hole reaching the target depth (DH 11-3643-10) after an extension by Hannan in 2018. The drill hole intersected 0.3 m @ 56.5% Zn+Pb at 166m depth high in a hanging wall of a fault. This was followed by multiphase calcite-dolomite breccias with gossanous patches after pyrite between 754-819m depth. The drill hole also intersected intense hydrothermal hematite alteration over 4 m width in the footwall of the potentially mineralized unit. The hydrothermal hematite alteration is highly significant as it lies proximal to mineralization at Irish-style deposits such as Lisheen, Tynagh and Silvermines and can be considered a near-miss indicator.
The Kilmurry fault system holds a series of drill ready targets (Figure 3) of which the high amplitude target is the first target to be drill tested. Subject to the results of the current drill hole, additional drilling may take place at other targets.
About the Clare Project
Hannan Metals Limited has 100% ownership of the County Clare Zn-Pb-Ag-Cu project in Ireland, which consists of five prospecting licences for 18,499 hectares. Zinc remains in tight supply amidst rising demand and stagnant supply. Ireland is a leading global jurisdiction for zinc mining and exploration. In 2015, Ireland was the world's 10th largest zinc producing nation with 230,000 tonnes produced.
The project hosts two target areas:
- The Kilbricken deposit in the northern part of the project. A maiden mineral resource, dated July 10, 2017, as amended and restated on January 28, 2019, immediately ranked Kilbricken as one of the top ten base metal deposits discovered in Ireland by tonnes and grade. Total indicated mineral resources were calculated as 2.7 million tonnes at 8.8% zinc equivalent ("ZnEq"), including 1.4 million tonnes at 10.8% ZnEq and total inferred mineral resources of 1.7 million tonnes at 8.2% ZnEq, including 0.6 million tonnes at 10.4% ZnEq.
- The Kilmurry relay fault system represents a syn-sedimentary relay fault system which exceeds over 15 km in length and is up to 2 km wide and represents one of the largest basin-scale displacements mapped in Ireland. Kilmurry lies 12 km south of Kilbricken.
