Osino Resources Corp. (TSX-V:OSI) (FSE:RSR1) (OTCQB:OSIIF)  is pleased to announce an update on the resource drilling at Osino’s Twin Hills Central gold project and the newly discovered Clouds mineralization on strike to the east. Clouds has so far returned a number of excellent results that include a high-grade shoot of 50m @ 1.75g/t as well as wider zones of consistently mineralized lower grade (inc. 77m @ 0.88g/t and 97m @ 0.65g/t). The ongoing resource drilling at THC has also returned additional excellent assay results which continue to define and improve the resource potential at Twin Hills.


The Twin Hills project is located in north-central Namibia, where Osino holds a dominant 7,000 km2 land position. The large-scale, sedimentary-hosted and structurally controlled Twin Hills gold system was discovered by Osino in 2019.


Dave Underwood, Osino’s VP Exploration commented: “The resource drill-out at THC is on schedule for the targeted maiden resource release at the end of Q1 2021. Assay results continue to indicate excellent continuity down dip and along strike with higher grades focused around fold hinges. Some of the latest holes have intersected mineralization over 350m down dip and still open. The new discovery along strike to the east at Clouds is also evolving positively with an excellent intercept of 50m @ 1.75g/t indicating potential for wide zones of higher-grade material. The Clouds East mineralization is currently 350m long and open east and west and promises to add significant ounces to the maiden resource. The recently commissioned structural study on THC has also added confidence to the deposit model and has provided a much better structural understanding. A second phase of structural work which started mid-January focuses on Clouds and the brownfields targets. We are particularly excited about the start of exploration drilling in February on the walk-up targets around THC, which include several magnetic, IP and gold-in-calcrete anomalies which have never been tested before.”


THC and Clouds Resource Drilling


The in-fill and step-out drilling to define a Maiden Resource Estimate at THC and Clouds is scheduled to be completed by end January 2021. The completed program will include approximately 60,000m of diamond and reverse-circulation drilling that will be included in the 43.101 compliant resource estimate, which Osino aims to publish by the end of Q1 2021. Drilling is being carried out on 50m x 50m drill spacing, covering the entire THC deposit and parts of the Clouds prospects to the east, with drill depths of 200m or more at 60 degrees inclination towards the southeast – see Figure 1.


The mineralization at THC and Clouds stretches over a total strike length of 3000m to date and is still open to the east. The mineralization is intersected by a series of NNW striking vertical faults in the ‘Gap’ but these do not appear to indicate major displacement – see model in Figure 3.


THC is remarkably consistent along strike and down dip with up to 259m (OKD118) of mineralized material and a down dip extent of over 350m and open to depth – see section in Figure 2. A number of holes drilled from the northern side of THC have produced shallow high grade material above the wide mineralized halo including OKRD069 which intersected 4m @ 11.67g/t from 56 – 60m.


The Clouds mineralization is characterized by a strong and coincident magnetic and IP anomaly and drilling results received so far indicate the potential for a significant mineralized body at Clouds East which is approximately 350m in strike length so far and open to east and west.

THC Results Discussion


Many of the results received since the previous news release (November 11th, 2020) are in-fill holes in the western and eastern lobes of THC. These assays indicate excellent continuity of grade and width within the two zones separated by a narrow area of faulting (the ‘Gap’) – see model in Figure 3. In-fill hole OKD097 in the western lobe returned 184m @ 1.12g/t.


In addition, a number of holes were drilled to the north of THC to intersect the plunging mineralization at depth and to test for blind parallel zones. To the north of the west lobe several holes intersected over 200m width of mineralization including holes OKD119 (236m @ 0.78g/t), OKD118 (259m @ 0.72g/t) and OKD091 (259m @ 0.74g/t). Hole OKD116 intersected 113m @ 1.00g/t to over 350m down dip and still going strong to depth – see section in Figure 2 below.


Hole OKD112 to the north of the east lobe intersected a zone of higher-grade mineralization from 220 to 295m (76m @ 1.09g/t). The higher-grade zone intersected in hole OKD112 is believed to represent the mineralized fold hinge of the Twin Hills Syncline which is sub-horizontal and east-west in orientation. This fold hinge will be modelled and targeted with the resource in-fill drilling.


An unexpected, shallow, high-grade quarts-pyrite vein system of 4m @ 11.67g/t was intersected in hole OKRD069 at a depth of 56m – see Figure 1. This mineralization is unusual for its very high grade but also because it is associated with pyrite, whereas all the other mineralization at Twin Hills is associated with pyrrhotite and arsenopyrite. This new vein system will be targeted in the next round of drilling.

Clouds Results Discussion


The initial drill assays at Clouds indicate potential to add significant ounces to the resource, in particular the eastern end of the system, 1200m east of THC – see Figure 1. Many of the Clouds assays have not been received yet but the early results include a best of 50m @ 1.75g/t as well as wider zones of lower grade (97m @ 0.65g/t) – see Figure 1.


The Clouds East mineralization is 350m in strike extent at the moment and open to the east and west. The IP chargeability anomaly continues strongly in the easterly direction where it links with the Barking Dog prospect. The host lithology and style of mineralization at Clouds appears to be the same as at THC and a structural study has been commissioned to confirm the geometry of the system.


Structural Interpretation


During December 2020, the company engaged Colin Porter, an experienced structural and ore deposit modelling consultant, to assist with the structural interpretation and refinement of the lithological model which will feed into the resource estimate.


Figure 3 is available at


The in-house model of a syncline overturned towards the south has been confirmed and refinements added to allow a tighter lithological framework for the footwall and internal waste. Porter also logged and modelled a number of late vertical NNW striking faults which are usually characterized by breccia zones containing calcite, quartz and pyrite. These late faults do not seem to displace the mineralization significantly in a lateral sense but appear to have caused vertical displacement, particularly in the ‘Gap’ area between the west and east lobes at THC – see model in Figure 3.
