Highlights
Rimfire’s primary objective is to build a globally significant scandium resource inventory at our Fifield and Avondale Projects. The Murga intersections announced today in conjunction with the upcoming Melrose resource are the first components in satisfying that objective.
Rimfire offers unique ASX exposure to scandium and we feel that the shallow mineralisation which occurs over a large footprint gives rise to the potential for Murga to host a large-scale scandium resource”.
Drilling details
100 Air core holes (FI2472 to FI2571 – 2,664 metres: Table 1) were drilled to determine the significance of a Rimfire 2023 reconnaissance air core drilling program which successfully intersected strongly anomalous scandium in multiple drillholes at Murga (See Rimfire ASX Announcement dated 3 October 2023).
At Murga, scandium occurs within a flat – lying weathered saprolite (clay) horizon overlying magnetic ultramafic (pyroxenite) intrusive rocks of the Ordovician-age Murga Intrusive Complex, which have been demonstrated from previous drilling at both Murga and the adjacent Melrose Prospect to be intimately associated with scandium mineralisation (See Rimfire ASX Announcement dated 6 December 2023).
The most recent air core holes were drilled on 100 x 100 metre centres at Murga North and on 400 x 400 metre centres over the remainder of the Murga Intrusive Complex. In total the drilling was carried out over an area of approximately 20km² with locations shown in Figures 4 and 5.
The drilling has successfully defined an initial 4 areas – Murga North, Murga Northwest, Murga East and Murga South within the Murga Intrusive Complex for immediate drill follow up Figures 2 – 6).
All are characterised by thick vertical widths of strong scandium anomalism (+100ppm) with little of no associated nickel and / or cobalt anomalism which is in contrast to other scandium prospects in the area.
Significantly all the areas remain open and further drilling is required to determine the lateral extents of the scandium at each location.
Also, several magnetic features within the Murga Intrusive Complex that were not assessed by this phase of air core drilling have (based on the latest drilling results) been subsequently identified as new scandium targets for drill testing. These targets are additional to the 4 areas detailed below and include a +1 kilometre – long, WNW trending linear magnetic feature immediately west of the Murga East scandium area (Figure 2).
