Minotaur Exploration has reported high-grade copper drill assays for the final 18 holes of the 2019 drill campaign at the Jericho deposit – a Joint Venture with OZ Minerals (80 per cent) and Minotaur (20 per cent).

Drilling concluded late July with 58 holes completed. The drill program focused on the parallel J1 and J2 copper-gold lodes along 2.3 kilometres of J1 and 1.7 kilometres of J2 down to only 250-300 metres below surface. Less than half of the known mineralised area of both lode structures was covered by this drilling. Previous drilling (2017-2018) shows mineralisation is developed along 3.7 kilometres of strike and down to at least 650 metres below surface. The full extent of the mineralisation remains unknown and is open along strike and up and down dip.
Interpretation of 2017-2018 Jericho drill core suggested mineralisation has a shallow to moderate plunge north within the host lodes. This trend was confirmed during the 2019 drill program as definition of three main shoots evolved. These are named ‘Matilda’ and ‘Jumbuck’ within the J1 lode and ‘Billabong’ within the J2 lode.
The company reported that mineralisation within the shoots “is typically thicker, higher grade and more consistently developed than surrounding mineralisation. The two separate lodes lie parallel and are approximately 120 metres apart”.
