Viking Mines has identified a second parallel lepidolite pegmatite trend at the Reung Kiet (RK) Lithium Project in Thailand, substantially increasing the project’s prospectivity with lepidolite being a lithium-rich mica. RK is a brownfields project and exhibits several outcropping lepidolite rich pegmatites along strike from historical open cut mines.
Viking has been conducting reconnaissance soil sampling, rock chip sampling and mapping programs since announcing a transaction with Lepidico Ltd in November 2016. This three-month agreement is to explore the option of establishing a joint venture to build a small-scale lithium carbonate plant at or near the RK project.
The Main Trend extends southwest along strike and exhibits excellent exposures of several lepidolite pegmatite dykes in a swarm of about 30 metres wide. Previous rock chip and channel sampling returned results of up to 1.9% Li2O.
The second, new Eastern Trend is 65-75 metres east of the Main Trend, about 1km long and runs parallel to Main Trend. Minor historical workings are present with individual dykes up to 4 metres wide. Rock chip sampling indicates Li2O grades of 0.99% to 1.49%.
Subtle lithium and rubidium anomalism suggest both lepidolite pegmatite trends are open to the north of the historical tin mine
Viking has designed a drilling program with further drill sites being assessed. The 22 hole program of about 2000 metres will test near-surface continuity, grade and widths of the parallel lepidolite pegmatites as well as the lepidolite pegmatite exposures to the south.
Viking is also advancing its rock chip sampling, soil sampling and geological mapping at the Bang I Tum Lithium Prospect to the north. Bang I Tum is considerably larger in strike extent. Once completed Viking will prioritise drilling programs.
Drilling is planned to commence as soon as practicable following the grant of the Reung Kiet exploration licence. Viking has been negotiating with several potential drilling contractors.
Drilling rigs will be deployed to Viking’s nearby Khao Soon tungsten project, over which Viking has an option to acquire 75%, so as to ensure rigs are secured. Upon issuance of the lithium exploration licences, drill rigs will be re-deployed to the RK project.
