Black Craig, page-3

So lets just recap a few points of the announcement 21 October:
"Commencement of a 2,500 m initial diamond drilling programme at the Blackcraig Lead-Zinc-Silver Project where mining was last undertaken in the late 18th and early 19th century."

"Planned drill holes between 150 and 300m in length will target mineralisation beneath the old workings (mined from surface commonly to a depth of approximately 45m). Holes will cover approximately 1km of strike extent of the potential 4.5km mineralised trend.

"Drilling will be carried out by Priority Drilling of Ireland and is expected to take around 2-3 months to complete, with first assay results expected while the drill program is ongoing."

Its around 3 weeks since drilling started. By now I'd assume they've completed the first few holes.
IMO this exploration is completely off the radar of the broader market and any indication of mineralization could push the share price up appreciably - bearing in mind the mkt cap ca $85 million doesn't even reflect Lindi.
The fact they've broadened the exploration way beyond Black Craig indicates they hold strong belief in this particular forgotten part of Scotland.
