Drill Assays From San Finx Sn-W Mine Confirm Significant Extensions of The High-Grade Vein Mineralisation

Rafaella Resources Limited (ASX:RFR) (‘Rafaella’ or the ‘Company’) is pleased to announce that assay results from three exploration diamond drillholes (‘DDH’) drilled, but never assayed, in 2015 by Valoriza Minería S.L.U. (‘Valoriza’) returned high tin grades from cassiterite mineralisation. These results will be included for the ongoing 3D geological model of the vein system and for a maiden JORC compliant Mineral Resource Estimate (MRE) for its 100% owned San Finx tin and tungsten mine1 (“San Finx”).

Investment Highlights

  • Drillhole 15DDPN01 (PN01) was in the NE extreme of the main UG development of Pozo Nuevo zone, and it returned:
    • 2.23% Sn over 1.50m, from 84.25m and
    • 1.12% Sn over 1.10m, from 174.90m.
  • Drillhole 15DDPN02 (PN02) tested depth extensions in the central part of Pozo Nuevo zone and intersected:
    • 2.12% Sn over 1.60m, from 287.50m, undercutting level 8 of the UG development, proving continuity of the vein system and good grades at depth.
  • Drillhole 15DDPN03 (PN03) was in the SW extreme of the main UG development of Pozo Nuevo zone, and it intersected:
    • 0.73% WO3 over 1.00m from 244.90m,
    • 0.55% Sn over 2.00m from 374.80 and
    • 0.61% Sn over 1.00m from 436.40m.
  • Cu assay returned an average grade of 0.30% Cu within the 0.25% Sn and W cut-off intervals, suggesting that the mine could generate copper concentrate by-product credits.
  • San Finx was producing a clean concentrate of both tin and tungsten as recently as 2017.

Managing Director Steven Turner said:“These results confirm the exceptional grades of both tin and tungsten that are characteristic of this mine and underpin the attractiveness of restarting operations as soon as possible. San Finx is a historically producing mine with simple metallurgy and a track record of selling high-grade clean concentrates under contract. Work is continuing with the JORC compliant mineral resource estimate, and these results will be incorporated into that study. The Board looks forward to updating the market with the final report in Q3 2022.”

Assay results from 3 deep DDH, drilled by previous owners

Rafaella Resources has received assay data from the three DDH re-coded as 15DDPN01 (PN01), 15DDPN02 (PN02) and 15DDPN03 (PN03) which were drilled by Valoriza with the objective of expanding resources at depth for the underground operation. Figure 1 shows the location of the drillholes and of the underground development projections.

Figure 1. San Finx Sn-W deposit showing the mineralized zones at surface and the projection of the underground development for the zones of Buenaventura and Pozo Nuevo. Collar and projection of DDH PN01, PN02 and PN03.

Table 1 is showing drillhole coordinates, depth and downhole survey.

A total of 71 samples from the 3 DDH, including QA/QC (blanks, standards and duplicates from both, pulps, and coarse rejects) were submitted to ALS preparation laboratory in Seville.

All intercepts above 0.25% cut-off (combined Sn + WO3) have been calculated, as shown in table 2. True thickness factor has been applied according to the angles measured directly from core.

Cu assay returned an average grade of 0.30% Cu within the 0.25% Sn+WO3 cut-off intervals, suggesting that the mine could generate credits from a by-product sulphide concentrate.

The mineralised veins intersected generally correspond with the NE system, showing high core angles, Corrections ranging between 0.50 and 0.95 have been applied for the true thickness factor. Note that for the shallower mineralised veins intersected by DDH 15DDPN01, drilled in the NE extreme of the Pozo Nuevo Zone and that corresponds with the NNE trending Campelo-Silva vein system, the true thickness factor applied was much higher due to the low angle that such veins have been intersected.

FPX Nickel Completes Production Run of Battery-Grade Nickel Sulphate to Support Discussions with Prospective EV Battery Supply Chain Partners

FPX Nickel Corp. (TSXV: FPX) (OTCQB: FPOCF) ("FPX" or the "Company") is pleased to announce successful production of additional battery-grade nickel sulphate from its Baptiste Nickel Project ("Baptiste" or the "Project"). Building on the success of previous testing campaigns, a production run was completed to produce larger quantities of nickel sulphate crystals. The nickel sulphate samples, which meet the strict target specifications for battery applications, will be provided to selected prospective downstream partners including pCAM producers, battery companies, and automakers pursuing supply security, traceable sourcing, and low carbon intensity production.

"The production of high-purity nickel sulphate further positions us to engage in strategic discussions with prospective downstream partners across the global EV supply chain," commented Martin Turenne, FPX Nickel's President and Director. "This milestone further demonstrates the strategic flexibility of the Baptiste awaruite concentrate and the technical maturity of the awaruite refining process."

Top 9 Nickel-producing Countries

The top nickel producing countries list has been shaken in recent years by Indonesia's rapid rise to the top, beating the Philippines and New Caledonia.

Demand for nickel is mounting. Stainless steel accounts for the vast majority of nickel demand, but electric vehicle (EV) batteries represent a growing application for the base metal as the shift toward a greener future gains steam.

But while nickel's long-term outlook appears bright, it may face headwinds in the short term. Nickel prices have been trending down since breaking US$20,000 per metric ton in May 2024 as weak usage coincides with strong output from top producer Indonesia.
