VANCOUVER, British Columbia, Aug. 11, 2021 (GLOBE NEWSWIRE) — Osino Resources Corp. (TSXV:OSI) (FSE:RSR1) (OTCQX:OSIIF) (“Osino” or “the Company”) is pleased to announce further results from the infill and expansion drill campaign at the Twin Hills project, Namibia. There are currently 7 diamond and 3 RC rigs on site to complete the infill and expansion drill campaign by November 2021.

A total 70,000m of in-fill and expansion drilling has been completed to date on the three zones of mineralization at Bulge, Twin Hills Central and Clouds East – which together make up the Twin Hills gold resource. The drilling is focused on converting the bulk of the resource (reported on April 12, 2021) to the Measured and Indicated categories as well as expanding the mineralization down dip. As expected, the infill drilling has filled in several gaps in the previous grade shell and will add greater confidence to the next iteration of the Twin Hills mineral resource. The campaign of expansion drilling has taken the mineralization at Clouds East from 150m to over 200m below surface and the deep drilling at Bulge indicates that the deposit is open below 400m.  

David Underwood, Osino’s VP Exploration commented: “Recent results at the Clouds East deposit indicate that the previously intersected high-grade shoot increases in width and grade with depth. This expansion at Clouds East offers potential for significant additional ounces when the next resource estimate is published, as intended for early 2022. The deep drilling at Bulge has also extended the consistently wide mineralized zone down to 400m below surface with no indication of it closing off. This development also indicates the possibility of taking the pit to greater depths in the next resource estimate. With 11 drill rigs active at the moment we continue to generate a wealth of geological and assay data, and our understanding of the Twin Hills gold system and its growth potential continues to evolve. We are excited about what the next few months of infill, extension and brownfields exploration drilling will reveal.”

Clouds East

The recent drilling at Clouds East confirms that the grade and width of mineralization improves with depth and indicates the potential to increase the size of the resource at this orebody. Hole OKD148 returned an intercept of 50m @ 1.82g/t Au at approximately 200m below surface while OKD211 returned 41m @ 1.27g/t Au at 100m below surface. Higher up-dip, this same mineralized zone is much narrower and only returned an intercept of 16m @ 1.31g/t Au (OKR271) clearly illustrating the increasing size of the ore shoot with depth. Please refer to Figure 1 below for further details.

Several additional holes are currently being drilled along strike to define this high-grade zone at depth. A hole at the northeastern corner of Clouds East (OKD206) appears to have just clipped the top of the high-grade shoot and returned 5m @ 7.86g/t Au, indicating that the high grade extends in this direction as well, as indicated in Figure 2 below.

Figure 1 accompanying this announcement is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/737ac77e-97e4-4c5d-b964-95ea384f6802

The section through Clouds East in Figure 1 above indicates the parameters used in Osino’s Technical Report describing the Twin Hills Gold Project, Namibia, dated effective April 1, which describes the Twin Hills Mineral Resource Estimate (“MRE”).

The greywacke syncline constraining the mineralization model is represented in dark blue and the grade shell which contains 0.4g/t Au and higher, is shown in orange.

Since publishing the MRE, the infill drilling has identified extensive additional mineralization at Clouds East that is likely to increase the size and grade of the mineralization within the grade shell, to be included in the next resource update.

The current MRE pit shell and the PEA pit design (please refer to the press release dated 14 July 2021) with benches are indicated on the section. The width and grade of the deeper mineralization discovered during the current phase of infill and step out drilling is likely to increase the depth of the pit bottom.

Twin Hills Central

The infill drilling at Twin Hills Central is nearing completion with the dense drill spacing resolving the mineralized deposit into a series of high grade, northeast plunging shoots, surrounded by lower grade material. The Twin Hills Central drilling, together with the additional infill and step-out drill assays received since the last press release is indicated in Figure 2 below.

Figure 2 accompanying this announcement is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/6a2edfac-0478-4b2e-9394-bcce2b723110

Of particular note is the shallow nature of the mineralization particularly at THC where some of the higher-grade shoots come close to surface below the calcrete cover, which is only about 5m thick at OKR307 as opposed to the average calcrete thickness of 20m over most of the remainder of the deposit.


The infill drilling at Bulge will take longer to complete than the other areas, as it needs to be carried out primarily using diamond drilling, to minimize deviation in the deep holes. The denser drill spacing is helping to fill in the previously reported gaps in the grade shell, which were due to the lack of data – see arrows pointing to gaps on OKD149 in Figure 3.

The section through the Bulge in Figure 3 illustrates the consistency of the wide mineralized zone from surface to 400m deep, and open to depth. The current phase of drilling is focused on filling in the gaps in the grade shell due to low data density, like those indicated by arrows on the figure.

In addition, there are holes being drilled from north of the MRE holes (e.g. OKD217) to intersect the mineralization further down dip. These holes are designed to confirm the continuation of the mineralized zone and the possibility of taking the pit deeper.

Improvements in Geological and Structural Understanding

A geological map of the bedrock beneath the calcrete cover has been compiled from the drill hole data, structural measurements on core and the detailed ground magnetic data. The contact between the meta-greywacke and the underlying cordierite schist was mapped in detail and offsets in the contact logged as displacement along structures.

A series of three holes were previously drilled in an east-west direction to cross over and map prominent structures. The east-west holes confirmed two prominent structures; one separating Bulge and THC and a second in the middle of THC – see Figure 1. Further prominent northeast striking structures have been inferred from borehole lithological data west of Bulge and west of Clouds East – see Figure 1.

These structures appear to control the higher-grade shoots that lie directly to the east of the structure. The plunge of the mineralized shoots (which is approximately 580 towards 0280) coincides with the intersection lineation of the northeast structures and the axial plane of the syncline hosting the mineralization.

This new understanding of the structural controls will help prioritize extension drilling as well as future brownfields exploration targets at Twin Hills.

2021 Drill Program Summary

Drilling is ongoing with 11 drill rigs (8 DD and 3 RC) which are active in resource, exploration and hydrology drilling and Osino expects to complete approximately 115,000m of combined DD and RC drilling during 2021.

Approximately 70,000m of RC and DD drilling has been completed for the year-to-date although a significant portion of the infill and expansion assay results are still outstanding. The completed drill meters are as follows:

  • 12,000m of resource drilling completed in Q1 and already included in the published MRE and PEA
  • 40,000m of completed infill and expansion drilling, awaiting some assays, not included in the MRE
  • 18,000m of brownfields exploration drilling completed year-to-date

A further 45,000m of drilling is planned for the remainder of 2021, comprising the following:

  • 20,000m of additional resource drilling (mainly deep DD holes up to 400m depth) is ongoing
  • 25,000m of additional exploration, grade control and technical study drilling is ongoing

Notes on Drill Assay Reporting:

  1. Total intercepts reported are unconstrained – all combined intercepts above 0.4g/t Au reported. GM values based on unconstrained intercepts. All reported intercepts are apparent widths rounded to the nearest meter. Included (incl.) intercepts are constrained at 0.4g/t Au cut-off, minimum 2m wide and no more that 2m internal dilution. True widths are unknown at this stage. 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 colours according to the GM_Class metric indicated in column 9 above.
