A technical review of a recently completed FYI Resources’ drill hole on the Sino-Lao Potash Project in Laos has confirmed the extent of potash mineralisation. The hole was the first drilled by FYI in its due diligence program at the project which is in the Natan Mining Area northeast of Vientiane.
The technical review of the downhole Natural Gamma log of the vertical drill hole was carried out by CSA Global. The entire hole was Natural Gamma logged through HQ steel casing by Aztec Engineering Co following completion of the hole.
The gamma sensor in the downhole probe estimates in counts per second (CPS) the level of Potassium-40, a radioactive isotope of potassium. In potash deposits elevated CPS indicates the presence of potash, either as carnallitite or sylvinite, as visually confirmed by site geologists while logging the core.
Of the 228 metres of potash-bearing evaporate seen in the drill core, the downhole probe identified three notable zones of elevated potassium response: 203.6-206.6 metres @ 160 CPS; 207.6-209 metres @ 190 CPS; and 306-320 metres @ 140 CPS.
The approximate average background natural gamma ray response of the evaporate sequence below the hanging wall halite is approximately 85 CPS.
FYI says that although the Natural Gamma log is indicative of potash mineralisation, the available data is not sufficient to allow any reasonable estimation of a mineral resource in isolation at this stage.
The company says the geophysics results add to the due diligence work and understanding of the project and further demonstrate its potential. It says they also add credibility to the strategy of entering a joint venture on the project.
FYI is continuing its due diligence and will work towards a JORC reportable resource estimate once it proceeds with a formal joint venture.
