- RC Drilling is progressing well at Machinga, with 7 holes for 840 metres drilled as part of a ~5,000m combined RC and DD program. The diamond drill rig is currently mobilising to site
- Machinga is enriched in heavy rare earths (Dysprosium (Dy) and Terbium (Tb)) and Niobium (Nb) (2010 trenching MATR003: inc.: 15m @ 0.45% with 0.75% Nb2O5 including 5m @ 0.54% TREO and 1.34% Nb2O5)1
- Drilling aims to follow up 2010 drill results which included: 11m @ 1% TREO (including 330 ppm Dy2O3) from 12m (MARC005) and 5m @ 1.5% TREO from 26m (MARC015)2
- A 200m by 50m soil sampling program has been completed over and to the north of known mineralisation at the Machinga North prospect, with the aim to delineate extension of mineralisation for follow-up drill testing
- Soil samples have been despatched to ALS laboratories in Johannesburg for preparatory work prior to full suite analysis in Perth
- Drill samples from the RC/DD program will be despatched to Intertek in Kitwe, Zambia for preparatory work prior to analysis in Perth
As announced on 29 June 2023, the Company has commenced a combined reverse circulation (RC) and diamond drilling (DD) program at Machinga. The Company has so far completed 7 RC holes for 840 metres of the ~5,000 drill program (Figure 1). The diamond rig is due to be mobilised to site by the middle of July.
Drilling at the Machinga North target – one of six targets identified to date within the Machinga concession – in 2010/12 returned intercepts of 11m @ 1.0% TREO with 330ppm dysprosium oxide (Dy2O3) from 12m (MARC005), 5m @ 1.5% TREO with 596ppm Dy2O3 from 26m (MARC015) and 3m @ 2.2% TREO with 295ppm dysprosium oxide (Dy2O3) from 66m (MARC033) including 1m @ 5.1% TREO with 584ppm dysprosium oxide (Dy2O3) from 67m.
Previous trenching in 2010 included: MATR001: 7m @ 1.26% TREO, MATR002: 33m @ 0.71% TREO (inc: 11m @ 1.00% TREO with 0.46% Nb2O5) and MATR003: inc: 15m @ 0.45% with 0.75% Nb2O5, incl: 5m @ 0.54% TREO and 1.34% Nb2O5.
Soil Sampling Program
The Company recently completed stage 1 of a phased soil sampling program at Machinga, to the north of known mineralisation (Figure 2). Sampling was undertaken on a 200m by 50m grid, with 256 samples collected.
The objective of the program is to define extensions of mineralisation along strike to the north, with the aim of proving up additional targets for drilling. Samples were despatched to ALS Laboratories in Johannesburg, South Africa for preparation, prior to a full suite analysis in Perth. Results are expected early August.
