Description
WORLD CLASS MINING JURISDICTION
- Located within the prolific Miocene polymetallic belt, approximately 34 km NNE of the Julcani Mine.
- Mineralisation occurs spatially and genetically associated with a sequence of volcanic and subvolcanic rocks, comprising coarse fragmental dome-diatreme andesite, massive porphyritic andesite and dacite dome facies.
- Historic drilling of 8,500 m in 41 holes defined a tabular, west dipping mineralised system approximately 1,800 m long north to south, up to 300 m wide east to west, and 200 m thick. The deposit, which is open in multiple directions consists of multi-episodic polymetallic (Ag-Au ±Pb ±Zn ±Cu) intermediate sulphidation epithermal mineralisation that often starts in drill holes within a few metres from surface.
- The Company has developed 3D geological models of the Ag-Au mineralization using the available drilling information and interpreted geological controls. Potential extensions to the mineralized envelopes have been used to outline a near surface exploration target of 15 to 35 Mt averaging between 50 and 60 g/t Ag, and 0.4 to 0.6 g/t Au containing some 25 to 60 MOz Ag and 0.2 to 0.7 MOz Au.
The potential quantity and grade of the exploration target is conceptual in nature and there has been insufficient exploration work and drilling to define a mineral resource and the full potential of the mineralisation. Moreover, it is uncertain if further exploration will result in the target being delineated as a mineral resource.

FLAGSHIP PROJECT
PROJECT CHARACTERISTICS
- 250 km ESE of Lima in Central Peru. 34 km NNE of the Julcani mine
- 8,500m historical drilling in 41 holes
DEPOSIT STYLE
- Intrusive dome – related epithermal Ag – Au
DEPOSIT DESCRIPTION
- 3.5 km x 400 m quartz- sericite alteration envelope
- At least two mineralising events: Au then Ag + base metals
- Drill confirmed mineralisation related to dome open to South, North and West
- Higher grade zone open to South
- Untested high-grade feeder potential
MINERALISATION
MINERALISATION
- Ag – Au mineralisation from surface
- Mineralisation dips approx. 40° to West
- Historical high-grade intercepts e.g. RC E10, from 30m depth intersected 107m from of 76 g/t Ag and 0.39 g/t Au, including 21m of 217 g/t Ag and 0.62 g/t Au
TARGETS
EXPLORATION POTENTIAL
- Near surface exploration target of 15 to 35 Mt averaging between 50 and 60 g/t Ag, and 0.4 to 0.6 g/t Au containing some 25 to 60 MOz Ag and 0.2 to 0.7 MOz Au
- The higher-grade mineralisation is contained within a much larger volume of moderately mineralized material that is open in multiple directions
- Untested high-grade feeder potential
* The potential quantity and grade is conceptual in nature, and more information and work is required to define a mineral resource. It is uncertain if this work will result in the target being delineated as a mineral resource.
