As reported last month, the explorer completed a shallow drilling program to test a surface gold anomaly to the southwest of the firm's Twin Hills prospect.
It was also aimed at extending the collection of samples along the Karibib fault between Twin Hills and the producing Navachab Gold mine, which is owned by QKR Namibia.
The program tested a portion of the gold anomaly in calcrete (a hardened calcium layer) which stretches for 8km to the southwest from the original 3km Twin Hills prospect.
The maximum gold assay value was 2.3g/t (grams per ton) and a further seven bedrock samples had values between 0.3g/t and 1.1g/t gold.
"These results indicate that the gold anomalies in calcrete at surface over the 11km strike length are representative of gold in the bedrock below the thick cover," Osino said.
"We have developed the ability to carry out effective exploration in a region with thick calcrete cover. This is a game changer for us.
"We discovered and grew the Karibib Gold Trend during 2018 and we are now advancing this district scale gold play and delineating drill targets for an extensive drill program later in the year."
Toronto based Osino also noted that a detailed ground magnetic survey was currently underway over the length of the Karibib Trend.
"Approximately 60% of the area was covered during Q4, 2018 and the balance will be completed during February, 2019," it said.
"The results to date indicate that the gold anomaly at Twin Hills is closely associated with an anomalous magnetic response.
"Magnetics will therefore serve as an important exploration tool in the covered areas."
Significant drill program planned
Osino is also planning a significant RC (reverse circulation) and diamond drill program for later in 2019, aimed at testing the expanded Twin Hills prospect and any additional targets generated along the Karibib Trend.
Osino's Namibian interests consist of 20 exclusive exploration licenses within the central and northern zones of the country's prospective Damara belt, mostly near to and along strike from the producing Navachab and Otjikoto Gold mines.
Osino is currently focusing efforts on developing the Karibib Gold project and defining new exploration targets in the Otjikoto East area and on other licenses.
