As part of a farm-in to earn 75% of three exploration licences in the region, the company has been progressing numerous targets over 746 square kilometres on highly prospective ground for precious and base metals.
Walkabout’s exploration team in the UK has conducted detailed mapping, sampling and a ground geophysical survey over the Blackcraig historical mining area and mineralisation trend.
The company's principal focus is on obtaining funding for the flagship development-stage Lindi Jumbo Graphite Project in Tanzania, while it has also been able to maintain exploration progress in Scotland.
Since finalisation of the farm-in agreement in late 2018, the company has been actively engaging with local communities, landowners and relevant councils providing updates on activities and intended programs in the area.
Walkabout has engaged the services of a Scotland-based social and community risk specialist consultancy to assist in this process, including the appointing of a community liaison officer.
“Unlocking untouched potential”
Chairman Trevor Benson said: “The historic East Blackcraig and West Blackcraig mines provide a distinguished legacy of lead-zinc mining in southwest Scotland.
“Modern exploration techniques are already unlocking the previously untouched potential of the associated mineralisation both in a regional and a brownfields context.
“The Blackcraig project is very exciting geologically with our early-stage exploration work potentially unlocking a new generation of high-grade base metal discoveries.”
Recent exploration includes reconnaissance mapping and sampling, and a close-spaced ground magnetics geophysical program that was completed the week before the COVID-19 lockdown in the UK was announced.
The recently completed close-spaced ground magnetics survey highlighted several NW-SE features parallel to the historical mining areas.
This survey, together with the dataset compiled from the historical mining records and observations during the fieldwork campaigns have been used to plan the first phase of drilling.
Planned collar positions will be ground-truthed as soon as travel in the UK is allowed and work is well advanced to get all the regulatory requirements in place.
Blackcraig mining history
The area around Blackcraig is well known for its historical high-grade lead-zinc mines with mineralisation discovered in 1763 during the construction of an old military road exposing sulphides in a hillside cutting.
Operations were initially exploited by underground mining in the latter half of the 18th century and were abandoned when it became difficult to de-water the mines.
They were reopened in the mid-1850s with sporadic production until 1917.
The East Blackcraig and West Blackcraig mines produced over 14,000 tonnes of lead ore, 1,200 tonnes of zinc ore and minor copper.
No further exploration work has been conducted and the only evidence of the mining era is the occurrence of a few abandoned and collapsed shafts and adits, spoil heaps and the foundations of some plant and buildings.
