Osino Reports Wide, High-Grade Intercepts Below Pit Shell at Clouds Deposit, Further Infill Results at Twin Hills Central & Bulge

 

 

 

 

 

Drilling Ongoing With 9 Rigs at Twin Hills Gold Project, Namibia

 

 

Highlights

 

  • Further wide, high grade intercepts returned from Clouds East including wide high-grade intercepts below the current resource pit shell:
    • OKD142 – 73m @ 1.42g/t (178-251m) incl. 37m @ 2.27g/t
    • OKR275 – 40m @ 1.50g/t (47-87m) incl. 18m @ 2.64g/t and 6m @ 1.06g/t
  • Further wide, consistent intercepts from infill holes at Twin Hills Central (THC) and Bulge including:
    • OKR184 – 92m @ 1.27g/t (7-99m) incl. 32m @ 1.99g/t and 18m @ 2.00g/t
    • OKR220 – 82m @ 1.07g/t (9-91m) incl. 12m @ 1.35g/t and 26m @ 1.76g/t
    • OKR274 – 60m @ 0.97g/t (124-184m) incl. 9m @ 1.82g/t and 4m @ 2.14g/t
  • 37,107m of the planned 42,000m infill drilling has been completed to date.
  • 18,549m of the planned 25,000m exploration drilling has been completed to date.
  • Assay results for more than 110 completed boreholes outstanding (infill & exploration)
  • Infill, expansion, and brownfields exploration drilling is ongoing with 9 drill rigs.

 

Osino Resources Corp. (TSX-V:OSI) (FSE:RSR1) (OTCQB:OSIIF) is pleased to provide an update on drill results from its ongoing infill and expansion drill program at Osino’s flagship Twin Hills Gold Project in the Erongo Region of Namibia.

 

Results include a wide, high-grade intercept at Clouds East from a deeper hole below the pit shell (OKD142 – 73m @ 1.42g/t, including 37m @ 2.27g/t). More than half of this intersected high-grade zone is outside of the current resource envelope, suggesting possible future incremental resource growth (refer to Figure 2 below).

 

The maiden resource was released on April 12th, 2021 including 0.43Moz @ 1.00g/t in the Indicated category and 1.47Moz at 1.08g/t in the Inferred category at a cut-off grade of 0.5g/t. The infill drill program is aimed at converting the bulk of the mineralization to the Indicated and Measured Categories and includes approximately 42,000m of drilling to be completed by July 2021. Further drilling is planned for the 2nd half of the year with the aim of delineating down-dip and strike extensions to the currently defined resource outline.

 

David Underwood, Osino’s VP Exploration: “The infill drill program is progressing at full speed and producing better than expected results. The drill holes at Clouds East beneath the maiden resource pit shell are intersecting wide zones of high-grade mineralization which is clearly improving at depth. This indicates the potential for a significant resource upgrade at Clouds for the next estimate and we are planning an expansion of the current drill program to include further deep drilling at Clouds, Bulge and THC.”

 

Infill Drill Program

 

A total of 37,107m of infill drilling has been completed since the program started in March 2021. This includes 14,620m of diamond core from 61 holes and 22,487m of reverse circulation from 163 holes. The program is being carried out on a staggered 50m x 50m pattern resulting in an effective maximum drill spacing of approximately 32m to 35m. This will result in conversion of a significant portion of the current Inferred resource to Indicated and Measured categories.

 

There are currently 4 Reverse Circulation rigs drilling the holes of up to 220m in depth around the margins of the modelled pit at THC, Bulge and Clouds and 5 Diamond rigs drilling the infill and step-out holes of greater than 220m depth.

 

Figure 1 below indicates assays to date in coloured dots (colour-coding according to gram-metres) and assays awaited are shown in white dots.

The remaining infill drill meters (4,893m) will be completed by July 2021. The current assay turn-around time is approximately 2 months, therefore the last batches from the infill drill program are expected to be reported in September 2021.

 

Clouds Infill & Expansion Drilling

 

Assays received after the previous press release (dated May 19, 2021) include an intercept at Clouds East from a deeper hole to the north and below the US$1700/oz pit shell (OKD142 – 73m @ 1.42g/t, including 37m @ 2.27g/t). More than half of this intersected high-grade zone is outside of the current resource envelope, indicating possible future resource growth potential – see Figure 2.

 

It is now clear that the Clouds East high-grade shoot continues to depths beyond 250m although the assays of some of the deeper step-out holes, outside of the resource envelope, are still outstanding. Additional step-out holes are currently being planned around OKD142 to test the down dip and strike extensions of the mineralization.

 

Other infill assays received in the Clouds area, including OKR282 (124m @ 0.73g/t), confirm consistency and width of mineralization from surface to about 150m in depth, contained within the US$1700/oz pit shell.

 

OKR275 (40m @ 1.50g/t from 47-87m) is on the western margin of the Clouds deposit and indicates shallow high-grade mineralization in that area.

Figure 2 above is a section through the Clouds East orebody including OKD142. The modelled resource envelope is represented by the blue color on the figure, while the 0.4g/t grade shell is shown in orange (the modelled resource envelope (blue) is distinct and different from the 0.4g/t grade shell). Results shown annotated in text box with blue boundary (OKR086 and OKR088) are assays reported previously. Note the extensive mineralization outside and below the current pit shell.

 

Twin Hills Central and Bulge Infill Drilling

 

Additional infill assays at Bulge and THC continue to produce consistent, wide mineralized intercepts (see Figure 3 below). Infill holes OKR184, OKR220 and OKR273 all produced wide zones of mineralization as expected and confirm mineralization from surface just below the calcrete cover.

 

Deeper infill holes (up to and beyond 450m drill depth) at Bulge and THC are being drilled with diamond rigs to test down dip and deeper strike extensions of the orebody as expected from 3-D modelling and structural interpretation.

 

The gap between Bulge and THC is steadily becoming smaller with more infill drilling and the latest results in the area include OKR274 with 60m @ 0.97g/t, including 9m @ 1.82g/t and 4m @ 2.14g/t. The gap is now down to less than 200m in strike length.

Table of Significant Intercepts

 

A selection of previously unreleased intercepts is presented in Table 1 below. The full table of significant intercepts is available on the website here.

 

Brownfields Exploration

 

A total of 18,549m of drilling has been completed to date on the brownfields targets. These targets are all within a 10km radius of the THC orebody and have not been tested previously. These assays have started to arrive and will all be reported in due course.

Notes on Drill Assay Reporting:

 

  1. Total intercepts reported are unconstrained – all combined intercepts above 0.4g/t reported. GM values based on unconstrained intercepts. All reported intercepts are apparent widths rounded to the nearest meter. True widths are unknown at this stage. Included (incl.) intercepts are constrained at 0.4g/t cut-off, minimum 2m wide and no more that 2m internal dilution. Collar positions are in UTM WGS84 surveyed by digital GPS.
  2. The GM number indicated in column 8 above is a commonly used short-hand method of representing gold grade (g/t) and unconstrained intercept width (m) as a single metric by multiplying the average intercept grade with the intercept width. The borehole collar color-coding in Figure 1 uses the same metric, with different colors according to the GM_Class metric indicated in column 9 above.

 

Quality Assurance / Quality Control

 

All Osino sample assay results have been independently monitored through a quality assurance / quality control 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, Namibia, near the Twin Hills Project. Drill core is sawn in half on site and half drill-core samples are securely transported to the Activation Laboratories Ltd. sample prep facility in Windhoek, Namibia. The core is dried, crushed to 90% -10mesh, split to 350g and pulverized to 90% -140mesh. Sample pulps are sent to Activation Laboratories Ltd. in Ontario, Canada for analysis. Gold analysis is by 30g fire assay with AA finish and automatically re-analyzed with Gravimetric finish if Au >5g/t. In addition, pulps undergo 4-Acid digestion and multi-element analysis by ICP-AES or ICP-MS. RC drill samples are prepared at Activation Laboratories Ltd. sample prep facility in Windhoek, Namibia. The RC chips are dried, crushed to 90% -10mesh, split to 350g and pulverized to 90% -140mesh. Sample pulps are sent to Activation Laboratories Ltd. in Ontario, Canada for analysis. Gold analysis is by 30g fire assay with AA finish and automatically re-analyzed with Gravimetric finish if Au >5g/t.
