Kaskara

Kaskara Copper-Lead-Vanadium Prospect

The Kaskara prospect lies on the Kaskara Trend on EPL 3542 (SBR 70%). Kaskara has been the product of a dedicated program of project generation and prospecting.

Kaskara is a significant prospect that has characteristics similar to many of the largest deposits of the region. There are many similarities to be drawn between Kaskara and nearby Tsumeb deposit and the Kipushi deposit in the DRC.

Throughout the Otavi Mountain Land and other areas in Botswana and Zambia, there is a Tertiary-aged low temperature hydrothermal event that has affected many of the base metal deposits of the region. This event has had a major effect on mineralisation at Kaskara, so that very little sulphide mineralisation has yet been encountered in drilling. The Company’s mineralisation model predicts primary sulphide mineralisation at depth below the oxide zone.

Regionally, Kaskara is located within a highly prospective dilational zone adjacent to a major fault. A jog in the fault is home to numerous mineral occurrences, including Kaskara, Lucas Post and Ondjima..

Mineralisation encountered at Kaskara is dominated by vanadates of copper, lead, and zinc. The main minerals are descloizite (zinc-lead vanadate), mottramite (copper-lead vanadate) and vanadinite (lead vanadate chloride). Hematite is also very common.


Unlike the unweathered rocks in the immediately surrounding area, the weathering profile at Kaskara is deep, and presently known to exceed 200 metres. This has resulted in a funnel-shaped oxide zone that is at its deepest in the mineralised zones, a feature common at major deposits in the region such as Tsumeb (900m deep weathering profile), Abenab (>300m deep), Berg Aukas (>500m deep), and Kombat (>500m deep).
 

RC Drilling

The nature of the mineralisation at Kaskara prevents effective diamond drilling in the oxide zone. This style of oxide ineralisation is largely peculiar to this area of southern Africa and is also observed in other locations in the OML associated with significant sulphide ore bodies such as the Tsumeb copper deposit to the north and the Abenab & Berg Aukas lead-zinc deposits to the east.


A total of thirty four holes (KKRC0018-0051) were drilled across the outcropping mineralised zone. The results show that Sabre has successfully intercepted broad zones of mineralisation at Kaskara, that extend to depth.

Significant intercepts included:

KKRC0020 19.00 m @ 1.01% Pb+Zn, 0.26% V2O5 & 0.10% Cu from surface
and 10.00 m @ 1.28% Pb+Zn, 0.09% V2O5 & 0.05% Cu from 114.00 m

KKRC0027 12.00 m @ 2.41% Pb+Zn, 0.73% V2O5 & 0.24% Cu from 31.00 m

KKRC0028 11.00 m @ 1.10% Pb+Zn, 0.21% V2O5 & 0.06% Cu from 56.00 m

KKRC0031 18.00 m @ 1.16% Pb+Zn, 0.27% V2O5 & 0.09% Cu from surface
and 21.00 m @ 1.09% Pb+Zn, 0.21% V2O5 & 0.07% Cu from 107.00 m

KKRC0032 35.00 m @ 1.17% Pb+Zn, 0.11% V2O5 & 0.31% Cu from 157.00 m

KKRC0035 16.00 m @ 1.01% Pb+Zn, 0.28% V2O5 & 0.07% Cu from 155.00 m

KKRC0036 23.00 m @ 1.17% Pb+Zn, 0.11% V2O5 & 0.06% Cu from 190.00 m
and 10.00 m @ 1.14% Pb+Zn, 0.34% V2O5 & 0.15% Cu from 234.00 m

KKRC0038 16.00 m @ 4.28% Pb+Zn, 1.30 % V2O5 & 0.26% Cu from 54.00 m

KKRC0045 10.00 m @ 5.39% Pb+Zn, 1.57% V2O5 & 0.16% Cu from 19.00 m

Kaskara is a large mineralised system, including extensive surface mineralisation and significant mineralised intercepts in drilling. The deep IP target at Kaskara remains only partially tested and requires down hole geophysics, together with digital modelling, to help better target the source of the anomaly at depth prior to further exploration.
