VANCOUVER, BC / ACCESSWIRE / January 25, 2022 / Hannan Metals Limited ("Hannan" or the "Company") (TSXV:HAN)(OTC PINK:HANNF) is pleased to report Hannan has doubled the number of systematic channel samples collected at the Tabalosos East prospect within the San Martin JOGMEC Joint Venture ("JV") sediment-hosted copper-silver project in Peru (Figure 1). Results continue to demonstrate high grades with continuity.
Highlights:
- Definition of a new zone of mineralization at Renaco that extends mineralization 3 kilometres further south than previously recognized, where a total of 17 channels average 1.1 metres @ 2.1% copper and 29 g/t silver. Highlights at Renaco include some of the highest grades seen on the project to date (Figure 2):
- CH3927: 0.4 metres @ 10.8% copper and 124 g/t silver
- CH243: 2.5 metres @ 2.7% copper and 61 g/t silver
- CH22317: 0.9 metres @ 4.4% copper and 76 g/t silver
Systematic surface channel sampling of the mineralized copper shale at surface has been conducted over 5 separate areas within a 9-kilometre-long by 1-kilometre-wide area that is interpreted to extend with shallow dips to the west for between 2-4 kilometres, with a target depth ranging from surface to 500 metres (Figures 2 and 3). New channel results include (Table 1):CH4321: 3.0 metres @ 3.4% copper and 36 g/t silverCH22330: 1.4 metres @ 5.5% copper and 68 g/t silverCH3917: 2.8 metres @ 1.9% copper and 34 g/t silverAcross Tabalosos East, which represents only 1% of Hannan's 656 sq km of tenure at the San Martin JV area, a total of 91 channels average 1.0 metre @ 1.9% copper and 28 g/t silver using a lower cut of 0.5% copper over 0.2 metres and range from 3.0 metres @ 3.4% copper and 36 g/t silver to 0.2 metres @ 0.6% copper and 2 g/t silver.Widths and grades remain consistent with the drill discovery of the Kupferschiefer copper-silver deposits in 1957.A geophysical trial induced-polarization pole-dipole survey will commence in February at Tabalosos East with the aim to map mineralization to depth.A public participation meeting with all stakeholders, to conclude the DIA drill permitting field work component, is expected to be held in February when recently implemented Peruvian COVID-19 capacity restrictions are lifted. |
Michael Hudson, CEO, states "Comprehensive channel sampling provides further excitement, with average widths and grades continuing to show context with drill numbers found during the discovery of the vast Kupferschiefer copper-silver deposits. We have also extended mineralization via channel sampling a further 3 kilometres south into the Renaco area with some of the highest grades we have seen on the project to date including channeling 0.4 metres @ 10.8% copper and 124 g/t silver. With social and geophysical programs planned for February we highly anticipate moving toward our maiden drill program in this expanding mineral system around the middle of the year".
At San Martin outcrop is extremely poor with <1% exposed rock in the area. Individual outcrops were located with the aid of soil samples and LiDAR surveying. Nevertheless, Hannan's detailed geological facies analysis across the project has identified the economic geological implications for high-grade stratabound sediment hosted copper mineralization that may have significant lateral continuity.
Copper mineralization is located at the base of a transition between the Sarayaquillo Formation and the Cushabatay Formation. This transition has previously been recognized in the district in academic literature, but is not well documented. The mineralized zone is located in the transition between fluvial-aeolian sediments and the onset of marine sedimentation. Copper mineralization is hosted in well-sorted sediments with the main reductant consisting of carbonized plant fragments varying in size from silt to several decimetres, at the top of a red-bed unit. Furthermore, initial observations suggest that the mineralization is mineralogically very simple with the dominant hypogene copper minerals being chalcocite and minor cuprite. Overall, the mineralization is extremely sulfur poor and very little sulfides can be observed in hand specimens. Leaching of the copper mineralization by supergene processes has been observed by Hannan geologists in some zones of Tabalosos and it is possible that the mineralization will show higher grades at depth due to the absence of surface leaching.
Context with the discovery of the Kupferschiefer
Sediment-hosted stratiform copper-silver deposits are among the two most important copper sources in the world, the other being copper porphyries. They are also a major producer of silver. KGHM Polska Miedz's ("KGHM") three copper-silver sediment-hosted mines in Poland (the "Kupferschiefer") were the leading silver producer in the world and seventh largest global copper miner in 2020. Quoted resources in 2019 for KGHM were 1,518 Mt @ 1.86% copper and 55 g/t silver from a mineralized zone that averages 0.4 metres to 5.5 metres thickness.
To provide context, Hannan's widths and grade (0.9 metre @ 1.9 % copper and 27 g/t silver) from 105 channel surface samples reported here at San Martin (lower cut 0.5% copper), within an area about 9 kilometres long and 1 kilometre wide, compare with those found during the initial modern-day drill discovery of the Kupferschiefer copper-silver deposits.
- In 1957 the discovery drillhole (Sieroszowice IG 1) intersected 2.0 metres @ 1.5% copper at the depth of 657 metres.
- In 1959 the Lubin-Sieroszowice deposit, based on the results from 24 drillholes contained 1,365 Mt @ 1.4% copper and 26 g/t silver in indicated resources, with a thickness ranging between 0.2-13.1 metres in an area about 28 kilometres long and 6 kilometres wide between 400 metres and 1,000 metres depth.
Hannan's sampling, to date, has been confined to surface channel sampling, although mineralization at Tabalosos East is interpreted to extend with shallow dips to the west for between 2-4 kilometres, with a target depth ranging from surface to 500 metres (Figure 3).
Technical Background
All samples were collected by Hannan geologists. Rock and sediment samples were transported to ALS in Lima via third party services using traceable parcels. At the laboratory, rock samples were prepared and analyzed by standard methods. The sample preparation involved crushing 70% to less than 2mm, 250g riffle split, pulverize split to better than 85% passing 75 microns. The crushers and pulverizes were cleaned with barren material after every sample. Samples were analyzed by method ME-MS61, a four acid digest preformed on 0.25g of the sample to quantitatively dissolve most geological materials. Analysis is via ICP-MS.
Channel samples are considered representative of the in-situ mineralization samples and sample widths quoted approximate the true width of mineralization, while grab samples are selective by nature and are unlikely to represent average grades on the property.
