Two of the Highest-Grade Intervals Drilled at the Twin Hills Project to Date



  • Two new holes at Clouds East intersect a shallow, high-grade shoot with intercepts of:
    • 8m @ 12.70g/t (OKR1791 – in wider zone of 54m @ 2.60g/t (from 58m)
    • 12m @ 5.24g/t (OKR1771 – in wider zone of 48m @ 1.86g/t (from 24m)
  • These holes are on strike with OKR092 (50m @ 1.75g/t including 7m @ 3.62g/t) previously reported
  • A second high-grade shoot intersected at Clouds Central:
    • 4m @ 13.71g/t (OKR137)
    • 4m @ 11.15g/t (OKR142)
    • 4m @ 9.09g/t (OKR099 – previously reported)
  • Infill drilling at Twin Hills Central with shallow, consistent and wide mineralized intercepts including:
    • 89m @ 1.68g/t (OKR1641) (from 57m)
    • 114m @ 1.09g/t (OKR1561) (from 31m)
    • 89m @ 1.15g/t (OKR1911) (from 34m)
  • A 25,000m exploration drill program on the Twin Hills satellite targets commenced on January 25th of which over 9,000m has already been completed.
  • Resource modelling has been expanded to include the eastern portion of the Clouds discovery.
  • NI 43.101-compliant maiden resource estimate (MRE) now expected by early Q2 2021, with the Preliminary Economic Assessment (PEA) expected later in Q2 2021.


Osino Resources Corp. (TSX-V:OSI) (FSE:RSR1) (OTCQB:OSIIF)  is pleased to provide an update on the resource and exploration drilling at Osino’s Twin Hills gold project including shallow high-grade intercepts at Clouds and further shallow, wide and consistently mineralized intercepts over 1 g/t from infill drilling at Twin Hills Central. The eastern portion of the Clouds mineralization will be brought into the Twin Hills resource estimate planned for completion by end Q1 2021.


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 and is being fast-tracked to development.


Dave Underwood, Osino’s VP Exploration commented: “The discovery of two high-grade shoots at Clouds is an exciting development at the Twin Hills project and is the first indication of the potential for really high-grade zones. The intercepts of 8m @ 12.70g/t, 4m @ 13.71g/t, 12m @ 5.24g/t etc. are the highest-grade intervals drilled at the Twin Hills Project to date, and we will be adding further holes around these shoots to determine their orientation and extent. These results prove that the Twin Hills mineralizing system focused gold into high-grade pathways and it is likely there are more to be found inside the current drilling footprint and in surrounding exploration targets. The in-fill resource drilling at Twin Hills Central continues to produce wide, consistent zones of mineralization and has reduced the size of the gap between the west and east lobes. An aggressive brownfields exploration drill program of 25,000m started at the end of January and is likely to be completed by May. The exploration program will cover many of the magnetic, IP and gold in calcrete anomalies not drilled to date as well as some conceptual, blind, structural targets.”


Mineralization and Geology of Clouds


The Clouds mineralization is associated with a strong IP anomaly which is almost continuous along strike from THC. See Figure 1. Drilling to date indicates that there is a well-developed zone of gold mineralization at the eastern end of the Clouds IP anomaly, while the central and western portions have produced more sporadic intercepts.


The best new results at Clouds East include:


48m @ 1.86g/t (58-106m) incl. 12m @ 5.24g/t (OKR177, from 58m)
54m @ 2.60g/t (24-78m) incl. 8m @ 12.70g/t (OKR179), from 24m)


Two of the recent holes drilled at Clouds Central also intercepted a narrow, high-grade shoot which is not contained within a broader halo of mineralization. The intercepts for these holes are:


4m @ 13.71g/t (OKR137, from 185m)
4m @ 11.15g/t (OKR142, from 35m)


The discovery of these high-grade shoots at Clouds is an important milestone for the project as it is proof that the Twin Hills mineralizing system can produce exceptional grades where the conditions are favorable. Further close-spaced drilling around these shoots is planned to model their size and orientation. This discovery also indicates the potential for further high-grade shoots not only within the current drilling footprint but also the amongst surrounding targets.

The drilling at Clouds East to-date indicates a tightly folded syncline with the axial plane dipping towards the north-northwest. The bedding at the south end of the syncline shallows somewhat indicating a possible anticline further to the south which will be tested during the next exploration phase. The core of the syncline contains a well mineralized interbedded greywacke unit which contains numerous parasitic folds and is sheared along cleavage and bedding planes due to fold amplification and flexural slip.


As at THC, the gold is associated with arsenopyrite and pyrrhotite mineralization and the wall-rock has undergone potassic alteration as well as silicification in higher grade zones. See section through Clouds East in Figure 2.


Figure 2: Section through Clouds East geology and gold mineralization


Mineralization at Clouds West appears to be located in the narrow limbs of the syncline at a higher structural level than the main closure seen at Clouds East. This may be due to the fold plunging more steeply to the SW at the western limit of the Clouds target. Broader zones of gold mineralization may therefore be located at deeper levels than drilled to date.


Twin Hills Central Resource Drilling


The resource drill program at THC has been completed and the balance of drill assays are expected this week. The latest drilling at THC has continued to produce consistent, wide mineralized intercepts on both the east and west lobes. The gap between the east and west lobes has also become considerably smaller as the drill density increased.


The drilling has included a total coverage of the known mineralization at a 50 x 50m grid and a small number of in-fill drill holes have been put in at 25m spacing. It is expected that the maiden resource will be majority inferred status. A follow-on in-fill drill program will be designed and implemented after the maiden resource estimate is released. Subject to QP confirmation, it is planned to complete at least 40,000m of infill drilling during 2021 in order to convert most of THC from inferred to indicated level. Final drill spacing required to do so will be confirmed by the QP, but it will likely be at 25 x 50m spacing, or less.
