Drilling results at Osino’s Ondundu in Namibia reveal previously unknown gold veins

Osino Resources’ drilling campaign at the Ondundu gold project in Namibia has identified previously unknown extensional veins. The infill and scissor hole drill programs at Ondundu includes the best intercepts recorded in Osino’s history. 

Scissor holes at Ondundu’s Razorback and Margarethental mineralised zones have intersected previously unknown mineralisation to the east of current resource indicating significant upside potential. 

Ondundu is a sedimentary hosted, structurally controlled orogenic gold deposit about 130km to the north-west of Osino’s flagship Twin Hills Gold Project. Twin Hills is close to the town of Karibib in the Erongo region of Namibia and is currently in the early stages of development.

Ondundu has a long history of mining and exploration, most recently by Canadian listed B2Gold who drilled 122 Diamond Drilling (DD and Reverse Circulation (RC) holes from 2016 to 2021.

Osino completed the acquisition of Ondundu from B2Gold in July 2022 and in October last year announced a maiden mineral resource estimate (MRE) for Ondundu comprising 26 million tonnes (Mt) at an average grade of 1.13 grams per tonne of gold (g/t Au) for a total of 0.9 million ounces (Moz) of gold in the Inferred Mineral Resource category (0.5g/t cut-off).

Osino’s recent Ondundu drill program was designed to upgrade the mineral resource around Razorback and conduct an orientation program to optimise drilling and assay methodology. Two scissor holes were drilled to check the frequency and grade of extensional quartz veins perpendicular to the main mineralisation.

According to Dave Underwood, Osino’s VP Exploration, the infill drilling program at Ondundu is producing exciting results which complements and expands on the previous drilling at Razorback by B2Gold in 2016.

“The wide intercepts at good grades confirm the robust nature at Razorback with one hole being the best intercept Osino has had anywhere in Namibia.

“Two scissor holes were drilled westwards to check for extensional veins at right angles to the resource drilling. Not only did these holes confirm the presence of previously unknown extensional veins, but also intersected new zones of mineralisation to the east of the resource in an area never previously drilled due to difficult access. This new eastern zone will be drilled out when the resource upgrade drilling gets underway,” explains Underwood.
