Orion Minerals defines new drilling targets at Prieska Zinc-Copper

- 2017-10-09 01:21:44 PM

Orion Minerals NL announced that drilling in the Deep Sulphide Target at its Prieska Zinc-Copper (Prieska) Project in South Africa has intersected a wide zone of high grade mineralisation in an area where historic data shows mineralisation blocked out and accessed with preparatory development but not stoped. In addition, and significantly, a new discovery has been made along strike to the northwest of previously reported mineralisation, with a 14.50m massive sulphide intersection being returned which provides a new target to extend the zone of wide, high grade mineralisation.

“Figures" referred to throughout this announcement can be viewed on the pdf version of the announcement, available on the Company's website, www.orionminerals.com.au.

Orion’s Managing Director and CEO, Errol Smart, commented on the results, “We continue to be pleased with drilling and exploration results from the Prieska Project. While drilling within the confines of historically drilled mineralisation continues to verify the grade and width as reported, our exploratory drilling is encountering very encouraging extensions to known mineralisation”

Deep Sulphide Target Summary

Assays have been received for hole OCOD068 drilled with the objective of validating mineralisation recorded to be intact in an area of historical trial mining. Hole OCOD068 intersected a wide zone of high grade mineralisation in an area where mine plans show mineralisation to be blocked out and accessed with preparatory development but not stoped prior to the mine closing in 1991 (Figure 1 and 2). The results for OCOD068 are set out below:


    - 23.30m at 5.45% Zn, 0.84% Cu, 0.18g/t Au and 6.8g/t Ag from 974.55m,

      including 10.35m at 6.92% Zn, 0.70% Cu, 0.18g/t Au, 5.95g/t Ag from 977.65m.


The intersection of mineralisation in this area represents a key finding as it confirms the limited extent of previous mining. Importantly, this intersection is in an area of high tenor in accessed mineralisation and strong geotechnical conditions, presenting an attractive target for potential early development. Deflection holes are currently being drilled off OCOD068 as part of the metallurgical sampling program.

OCOD068 intersected mineralisation in an area with a number of historic intersections (Figure 3). The correlation between these holes is shown in Table 1. True widths are quoted for the historic underground holes, while the OCOD068 intersection is at high angle to mineralisation and is close to true width. The results of OCOD068 fall well within the range of the historic intersections and further validate the historic data.
