Masiqhame Project (South Africa)

Masiqhame

In April 2016, Orion entered into a binding option agreement to earn up to a 73% interest in Masiqhame Trading 855 Pty Ltd (Masiqhame), which holds a prospecting right covering an area of almost 980km2 located 80 kilometres north of the PC Project (Figure 1). The Masiqhame prospecting right is located in easily accessible flat-lying countryside and is well situated with regional grid power and rail lines within 10km of the site. A good all-weather dirt road passes within 800m of the deposit.

Orion has targeted the large Masiqhame prospecting right after analysing regional data which points to the potential for three significant styles of mineralisation:

  • Zinc-copper VHMS-SEDEX mineralisation in the Areachap-Copperton Province;
  • Nickel-Copper mineralisation hosted in mafic intrusions analogous to the Jacomynspan Deposit; and
  • Pegmatite hosted mineralisation such as lithium, beryl and REEs in the Orange River pegmatite belt.

Orion believes that the integration of geochemical and geophysical methods may quickly enable new targets to be identified within the Masiqhame Prospecting Right, which overlies a highly prospective VMS horizon extending over more than 30km of strike. This horizon contains numerous published occurrences of copper-zinc and zinc-copper mineralisation associated with massive sulphides.

Historical Exploration

Mapping and sampling of the outcropping massive sulphide has been carried out since colonial settlement was first established in the Northern Cape. Numerous companies including Anglo American, Phelps Dodge, Anglovaal and Iscor (now Kumba) have explored the Areachap Terrane. The success of exploration at Prieska, Prieska Annex and Jacomynspan also led to declining exploration activity at the other prospects.

In general little work was done away from mineralised targets of surface or sub-cropping nature, most of which were identified by regional geochemical and mapping then followed up by geophysical surveys (IP and pulse EM) and shallow drilling. However du Toit (1998) notes that at the Boksputs Prospect, only one sulphide body has formed a gossan and the remainder are blind to surface. The Kantienpan deposit is also blind to surface and was discovered by EM methods. Roussow (2003) notes that much of the previous exploration was carried out prior to advances in the deposit model for VMS and SEDEX mineralisation. This increases the potential for further sulphide mineralisation to be identified on the Masiqhame prospecting right.

Drilling at the Kantienpan Deposit was curtailed soon after discovery, due to a corporate decision by Iscor to stop all exploration and focus on Iron ore production. As a result a number of additional litho-geochemical and geophysical targets remain to be tested on the Prospecting Right Area.

Orion believes that the integration of geochemical and geophysical methods may quickly enable new targets to be identified within the Masiqhame Prospecting Right, which overlies a highly prospective VMS horizon extending over more than 30km of strike. This horizon contains numerous published occurrences of copper, zinc, copper-zinc and zinc-copper mineralisation associated with massive sulphides.

Kantienpan Deposit

The Kantienpan Deposit is one of a number of Volcanogenic Massive Sulphide (VMS) hosted zinc-copper occurrences in the area of the Masiqhame prospecting right. The deposit was targeted by a combination of magnetic and time-domain electromagnetic ground surveys, following up on alteration identified by rock-chip sampling (Rossouw, 2003).

A total of 14 diamond core holes for 3,199m were drilled at the Kantienpan Deposit by Iscor (Figures 2 and 3). Significant intersections are detailed in Appendix 1 including the following results:

  • 8.84 metres at 6.32% zinc and 1.02% copper (KN005);
  • 6.15 metres at 4.74% zinc and 0.49% copper (KN010);
  • 7 metres at 3.15% zinc and 0.57% copper (KN007);
  • 13 metres at 3.96% zinc and 0.36% copper (KN003); and
  • 2.6 metres at 6.59% zinc and 0.35% copper (KN011).

Drilling has confirmed the presence of significant mineralisation extending from 80 metres – 250 metres below surface and along 800 metres of strike. Mineralisation at the Kantienpan Deposit remains open both along strike and at depth.

Drilling is currently underway at the Kantienpan Deposit, with an initial intersection of 7m at 6.44% Zn and 0.43% Cu in OKNR014.  Latest results will be available in our ASX announcements.

Commercial Terms

Option Agreement – Masiqhame (South Africa)

The Company has a binding term sheet for an exclusive option to acquire up to 73% in Masiqhame Trading 855 Pty Ltd.  The exclusive option allows the Company to undertake due diligence on the corporate entity and prospecting rights until 30 September, 2016.  This option was exercised 28 September, 2016.

To achieve 50% interest, the Company will invest ZAR1.5 million into Masiqhame and these funds will be used for initial exploration works.  The Company’s interest can increase to 73% upon completion of a feasibility study and application for Mining Right, funded through a loan account between the two parties.

With the option now exercised, the Company is working towards the Completion date, 28 October 2016, to earn the initial 50% interest in Masiqhame.  At the time of exercise, the Company was well advanced in meeting this investment commitment, as noted above.

Upon initial investment, the Company will also be appointed managers and operators of the prospecting rights, with representation of directors on the board of Masiqhame.
