Bendi Gold Project
18,900 hectares under application
Department of Puno, south-eastern Peru
The Bendi Gold Project is located in the Puno Orogenic Gold Belt (‘POGB’) in south-eastern Peru where staking to date has been based on Palamina’s current understanding of prospective geological structures in the Benditani Mine district and their relationship to historical and current operating small-scale gold mines in the area.
The Palamina mining concession applications in the Benditani Mine district are located in the Carabaya Province, Coasa District, in the northeastern Puno Department and accumulate some 18,900 hectares. The Benditani gold-mining district, dating back to pre-Inca-Colonial times, currently has some 10 mines in active operation with up to 15 occurrences of gold mineralization. Some of the better known mines include Benditani, Quoquellusta, Monteflor, Cuchilla, Caymen de Oro, Santo Domingo mines.
Access to the Benditani properties is a 7-hour drive from the domestic airport at Juliaca via the towns of Crucero, Coasa and Esquena. Elevations at Bendi fluctuate between 2,500 to 4,300 metres and due to the altitude rock exposure is generally excellent over the majority of the properties.
Staking focused on covering 2 district-scale structures identified by Palamina’s field work. The first a >7 km long thrust-related shear-zone occurring sub-parallel to the Benditani mine structure along which Palamina reports chip samples returning 25.4 and 9.9 g/t gold at the Mantos Gold Anomaly. The second a >15 km long, sub-parallel NW striking structural corridor developed in the core of an anticline. Palamina has discovered an area of anomalous gold along this feature – the Carol Anomaly which returned 4 metres grading 0.25 g/t gold in chip samples collected south-west of the third party Huacolcota producing mine.
Mantos Gold Anomaly
The open-ended 150 m long x 50 m wide Mantos gold anomaly is associated with a > 7 km long, Andean-trending compressive shear-zone occurring in fine-grained siltstones and sandstones of the older Sandia Formation which locally unconformably overlies the slates and siltstones of the younger Ananea Formation. Tectonic compressive-deformation events resulted in NW-SE trending shear-zones, thrust faults, and synclinal and anticlinal folding with minor incidence of NE-SW trending faults, which in turn also result in additional deformation of the host rocks to the orogenic gold mineralization.
The principal mineralized target at Mantos is associated with the western limb of a large anticlinal structure and appears to occur as a discrete package, or ‘manto’, hosting narrow mineralized quartz veins and veinlets generally oriented sub-parallel to the bedding of the fine-grained sediments, but occasionally transecting across bedding boundaries. Some 68% of a total of 69 chip samples resulted in anomalous Au/As values with the two highest gold assays returning 25.4 and 9.9 g/t gold.
Carol Gold Anomaly
The 2.5 km long by up to 30 metre-wide structure hosting the open-ended Carol gold anomaly (300 x 15 metre), is associated with a recently identified > 15 km long NW-SE trending anticlinal feature which transects the southwestern sector of the Bendi Gold Project. Some 1.5 km of the principal exploration target area is located over the eastern limb of the anticline and occurs as brecciated orogenic quartz veins and tectonically fragmented and foliated host rocks. Fine-grained Ordovician to Devonian-aged sediments host this anomalous zone (in such environments anticlinal features can provide optimum ‘traps’ for mineralizing fluids).
Mineralization in the brecciated quartz veins occurs as disseminated sulphides with >10% FeO in the matrix of this prospective gold-anomalous ‘breccia’. Palamina chip sampling from an outcrop south-west and on strike from the third party Huacolcota producing mine returned a 4 metre width grading 0.25 g/t gold.
Further chip sampling and rock-channel sampling is being carried out to further define both zones.
Focus on the POGB
The Puno Orogenic Gold Belt (POGB) covers approximately 175 km x 75 km on the eastern side of the Andes in south-eastern Peru. Known mineralized structures in the POGB extend up to 6 km in length with widths ranging from 0.2 m up to 2.0 m, within mantos up to 40 m in width. Palamina has secured the mining rights to 5 district scale land positions within the POGB where informal miners are actively mining visible gold. Palamina is actively exploring the Gaban and Coasa gold projects in order to identify suitable drill target areas to ultimately define economic gold resources while carrying out limited exploration programs on its Cori, Orco and Bendi gold projects.
