Drilling to Commence on High Priority EM Target at Boksputs
Electromagnetic conductor detected straddling the boundary between Orion’s Masiqhame Prospecting Right and
the newly granted Boksputs North Prospecting Right
- Orion receives grant of Boksputs North Prospecting Right.
- Follow up survey confirms EM anomaly straddling the boundary between Masiqhame and Boksputs
North Prospecting Rights.
- Survey data modelled revealing an EM anomaly containing a highly conductive 3000s - 6000s plate.
The conductor lies along the trend of recently drilled copper gold mineralisation associated with a 600
Siemens conductor.
- Diamond drilling to test the conductor will commence immediately.
Orion’s Managing Director and CEO, Errol Smart, commented:
“A fixed loop electromagnetic survey (FLEM) 2,500m north, along the trend of our recent Boksputs copper gold
drill intersections has detected a conductor with nearly ten times higher conductance than the FLEM target
previously drilled.
“We have also received notice of grant of a new Prospecting Right covering the area north of the new high
priority target allowing the FLEM survey to cover the open extension to the north of this very exciting target.
“Our previous FLEM survey conducted in 2018 detected this anomaly, but the target was modelled to lie outside
the survey loop requiring a new survey to provide data over the optimum area to model the target more
accurately.”
Orion Minerals Limited (ASX/JSE: ORN) (Orion or the Company) is pleased to announce that diamond drilling is
to commence immediately on a high priority target detected by a fixed loop electromagnetic (FLEM) survey on
the boundary of Orion’s existing Masiqhame Prospecting Right and a newly granted Boksputs North Prospecting
Right.
The Boksputs Prospect
The Boksputs Prospect, which is located on the northern boundary of the Company’s Masiqhame Prospecting
Right, has recently delivered very encouraging copper-gold intersections on the 600s B4 FLEM conductor,
including a best section of 5m at 1.09% Cu and 0.13g/t Au, including 1.00m at 2.38% Cu and 0.29g/t Au (refer
ASX release 25 January 2021). A follow up FLEM survey of the B1 conductors previously detected in two small
survey loops located 2,500m to the north of B4, on the boundary of the prospecting right (PR) and continuing
north of the PR, has now confirmed a very strong (3000s - 6000s) continuous conductor, DP1, that presents a
compelling drill target (Figures 1 and 2).
The strike extension of this target is also now accessible to Orion after receipt of the grant notice for prospecting
right NC12197PR, covering the northern extension of the target (Figure 3).
