Assay results from the last eight holes of the programme were located in the vicinity of the southern periphery of a historic mineralised body.
The findings will be used in a new conceptual 3D-model and grade-tonnage estimates for the project.
"This final batch of results support our view that the project will be boosted by peripheral, at or near-surface, mineralised karsts and zinc oxides,” said Colin Bird, Galileo chief executive.
Bird added: “We have engaged an independent geological consultant to develop, amongst other things, a conceptual (3D-model) grade-tonnage estimate based on differentiation of the material into medium (3-20% Zn) and high grade (>20% Zn) domains.
“We expect from this exercise and futher study to be able to direct the next exploration and drilling programme with a view to further increasing the size of the deposit and to generate a compliant maiden resource estimate.”
