A total of 142 rock chip samples have been obtained and sent for assaying.
The Las Tapias geological complex is centred on a circular structural feature, which is circa 1,100 metres in length and 800 metres wide.
The mineralised pegmatite is 300 to 400 metres long with a width of 150 to 200 metres.
Additional, large pegmatite veins and dykes, exceeding 15 metres in thickness, exist along fault structures surrounding the main pegmatite.
Dark Horse has access to a large portfolio of mineral exploration ground in Argentina through its progressive acquisition of domestic company Pampa Litio SA, of which it currently owns 25%.
Pampa Litio holds four separate exploration licences in the San Luis province totalling 34,000 hectares.
The company also holds an option to acquire the Las Tapias Mine in the Cordoba province, consisting of 6 current mining licences and a surrounding exploration licence.
Dark Horse’s objective is to discover and define a large lithium rich pegmatite resource, develop mines to produce lithium ore and ultimately a production facility in Argentina.
The company is aiming to manufacture battery grade lithium hydroxide for sale into the international battery and electronic markets.
