- Assays received for a further 16 RC and diamond drill holes at Twin Hills Central
- 26 of 31 holes from the Phase 1 and 2 drill programs intersected significant gold mineralization, with several exceptional new intercepts including wide zones of mineralization with high-grade shoots
- Highlights from the latest results include:
- 92m @ 1.40g/t (20 – 112m), incl. 35m @ 2.54g/t
- 37m @ 2.58g/t (173 – 200m), incl. 8m @ 7.50g/t
- 68m @ 0.99g/t (8 - 76m), incl. 24m @ 2.07g/t
- 54m @ 0.89g/t (90 – 144m), incl. 13m @ 1.44g/t and 5m @ 2.03g/t
- Highest individual meter assays include 52.0g/t, 18.3 g/t, 15.8g/t and 15.2g/t
- The strike of confirmed gold mineralization has now increased by 50% from 800m to 1200m and remains open to the east, west and at depth
- The objectives of the drill program included defining higher grade shoots, testing strike extensions at Twin Hills Central and completing initial drill traverses at Twin Hills West, Barking Dog and Clouds
- The balance of Phase 2 drill results from all targets is expected before the end of
January 2020

Significant intersections include 92m @ 1.40g/t (OKD024) and 37m @ 2.58g/t (OKD022). The latest results increase the strike length of gold mineralization by 50% to 1200m (open both east and west and at depth). The Company is anticipating receipt of additional results from 2 holes at THC as well as 14 holes at Twin Hills West, Clouds and Barking Dog. Previous results were reported in news releases dated
Assay Results for Twin Hills Central Drilling
Assays have been received to date for a total of 16 reverse circulation (RC) and 8 diamond (DD) holes from the Phase 2 drill program at Twin Hills Central which ended in early

In the diagram above, borehole collars have been color-coded according to a commonly used shorthand method of ranking gold intercepts: Multiplying intercept average grade (g/t) by width (meters) resulting in a “g/t x meter” intercept measure (combining both average gold grade and intercept width into a single metric known as “Gram-Meter”). On this basis, Osino considers any intercept of more than 50 as very good and any intercept of more than 100 as exceptional.
Using this metric, Osino has a total of 9 exceptional and very good intercepts out of 31 holes drilled so far (since
Twin Hills Central remains open along strike towards the east and west, and down dip at depth below 200m.
The next phase of drilling at Twin Hills Central will focus on closing off the mineralization towards the south, following the emerging high-grade shoots towards the south west and east as well as ongoing infill drilling.
Initial results for Twin Hills West, Clouds and Barking Dog will be reported once the balance of assays have been received. The next phase of drilling at these targets will be planned to follow up all significant assay results.
Following receipt and interpretation of all remaining assay results, Osino will compile and announce the expected 2020 work program. This is expected to be published in January/

1 Unconstrained intersections
*Drilled in NNW orientation (opposite to all other holes) to ascertain continuity
Notes: All reported intercepts are apparent widths rounded to the nearest meter. True widths are unknown at this stage. Included intercepts are at 0.4g/t cut-off, minimum 2m wide and no more that 2m internal dilution.
Geology and Structure
The meta-greywacke unit is underlain by biotite schist and cordierite schist. Sulphide minerals include pyrrhotite, arsenopyrite and pyrite in veinlets and as disseminated alteration. Geochemical data indicates a strong correlation between gold and arsenopyrite within the meta-greywacke unit.
The assay results to date clearly indicate the presence of structurally controlled high-grade shoots within the larger mineralized halo. The process of modelling geology, structure and grade in 3-D has now commenced prior to the planning of the next drill program.
Qualified Person
Quality Assurance
All Osino sample assay results have been independently monitored through a quality assurance / quality control ("QA/QC") program including the insertion of blind standards, blanks and duplicate samples. QA/QC samples make up 10% of all samples submitted. Logging and sampling is completed at Osino’s secure facility located in Omaruru near the
