Europa Metals Ltd (AIM:EUZ, JSE:EUZ, OTC:EOPAF) has initiated a new drilling programme at the Toral lead-zinc project in Castilla y León in Spain.
A series of holes will be drilled at depth, targeting an increase in the existing JORC indicated resource.
Separately, a geotechnical drill programme has now been completed.
"Europa Metals continues to progress its work programme on a number of fronts,” said acting chief executive Myles Campion.
“Following a slight delay, the drill rig is now on site and I am pleased to get our 2022 resource drilling campaign underway, which seeks to target additional resources at depth."
In March, Europa announced the results of ore sorting and metallurgical work which showed that 94% of the overall lead and zinc in the feed could be recovered.
Consultant Wardell Armstrong is currently nearing completion of its first stage rougher tests on all samples and will then proceed with final locked cycle testwork.
Europa Metals intends to utilise the findings and the tailings and rejects from the metallurgical and ore sorting test work to establish a picture of how best the company can use such waste products as both backfill and paste fill for potential future quarry reclamation and underground mining operations.
