Osino Resources Announces Drill Results and Discovery of New System with Large Scale Potential
Oasis and Wedge are Goldkuppe extension targets located up to 2,500m along strike to the southwest of Goldkuppe (refer to Figure 1 on next page). Drilling in the area was targeting a surface geochem and structural target within the prospective schist geology located stratigraphically below the Goldkuppe carbonates, and in rocks similar to the nearby Navachab Gold Mine located 30km to the southwest which has a global resource of more than 5moz and is currently in production.
Heye Daun, Osino’s CEO, commented: “We are very excited about the results and on-going interpretation of our Goldkuppe extension drilling campaign, particularly at Oasis and Wedge where we achieved some very encouraging drill results. Osino was successful in intersecting high grade veins within a thick package of lower grade, more disseminated schist material. This is especially exciting as this represents a style of gold mineralisation not previously seen at Goldkuppe, with large-scale potential and many similarities to Navachab Gold Mine.”
The gold mineralisation at Oasis occurs within a broad unit of banded marble which has been highly altered to skarn and calc-silicate. The best hole at Oasis is OJR210 which intersected several high-grade quartz-sulphide veins which occur within or adjacent to narrow calc-silicate layers. Assays of 9.45 and 6.95g/t Au over a metre each are contained within lower grade haloes of 10m @ 1.58 and 8m @ 1.45g/t Au respectively, all contained within a disseminated zone of 45m at 0.75g/t Au. This gold bearing zone is open to the north and south as well as down dip. The gold mineralisation at Wedge North, 1,000m to the southwest of Oasis, is similar in style to Oasis and is possibly the strike continuation of the same large-scale system.
At Wedge South two holes were drilled to intercept gold mineralized quartz veins sampled at surface which returned an assay of 5.48g/t Au. These veins occur within biotite schist just below the contact with the marble. The best intercept is in hole OJR215 which returned 10m @ 2.00g/t Au within intensive (diopside – garnet) skarn altered schist. Soil sampling and mapping indicates that this mineralisation continues to the southwest.
Gold at Calidus, North End and Spang occurs in boudinaged, massive sulphide (pyrrhotite) zones within dolomitic marble. These sulphide zones generally occur near fold noses and are associated with skarn alteration. Similar larger scale massive sulphide zones at Goldkuppe Central returned intercepts of 22m @ 3.44g/t and 28m @ 1.75g/t Au. Calidus, North End and Spang are located along strike, approximately 1km northeast of Goldkuppe.
Goldkuppe is a large (3,000m long) mineralised system with gold occurring in several discontinuous, plunging shoots. The geology of the Goldkuppe Prospect is dominated by a series of interbedded marble and dolomite units belonging to the Karibib Formation.
The marbles are folded into an anticline which plunges gently to the northeast with beds dipping to southeast. These marbles are underlain by biotite schists which form into an anticline approximately 1km towards the southeast in the Oasis and Wedge area and which outcrop further to the southwest at Wedge South.
The drill program testing the Goldkuppe extension and adjacent targets was completed in late 2017 but was hindered at that time by a delay in assay results from the laboratory. The results have now been received and interpreted and the schematic drill plan in Figure 1 below indicates the location of the most significant drill holes and intercepts at Goldkuppe, Oasis and Wedge, together with the geological and structural setting.

A large part of Goldkuppe remains untested.
A detailed magnetic survey, in-fill soil sampling, rock chip sampling and mapping are currently underway at Oasis and Wedge and will be completed in August. A follow-up drill program is planned for September 2018.

Note: Intersections of significance are reported using a cut-off of 1g/t Au for the downhole weighted average of the continuous interval. The maximum gold assay reported is 9,45g/t over 1m and no top cutting has been applied to the assay data. All intersections reported are considered apparent width as the strike and dip of mineralization is currently unknown.
Quality Assurance
All Osino sample assay results have been independently monitored through a quality control / quality assurance ("QA/QC") program including the insertion of blind standards, blanks and pulp and reject duplicate samples. Logging and sampling are completed at Osino’s secure facility located in Omaruru near the Goldkuppe project. Drill core is sawn in half on site and half drill-core samples are securely transported to the Actlabs sample prep facility in Windhoek, Namibia. The core is dried, crushed to 95% -10mesh, split to 250g and pulverised to 95% -150mesh. Sample pulps are sent to Ontario, Canada for analysis. Gold analysis is by 30g fire assay with AA finish and automatically re-analysed with Gravimetric finish if Au >5 g/t. In addition, pulps undergo 4-Acid digestion and multi-element analysis by ICP-AES or ICP-MS.
