Santa Comba Tungsten Project - Resource Expansion Plans

Investment Highlights

RFR is developing a 3D model for the high-grade veins at Santa Comba with the main objective of expanding the

use

current JORC compliant Underground (UG) Inferred resources of 0.234Mt @ 0.95% WO3 and 2,797ppm Sn for

2,221 tonnes of contained WO3 and 655 tonnes of contained Sn (0.53% WO3 cut-off) at Mina Carmen1.

UG development conducted by COPAREX in the 1980s at Mina Carmen extended for more than 1km southwards

from the current open pit (OP) resources, demonstrating significant upside potential for UG resource expansion

both to the south and at depth.

Ongoing UG detailed geological mapping of the southernmost UG development at Carballeira area, located 1km

south of the current OP resources, has demonstrated the presence of large endogranite intrusions including zones

of disseminated ore, confirming the upside potential for OP resource expansion to the south as a brownfield

exploration target.

The previously announced near surface Exploration Target evaluated using JORC (2012) guidelines, stands at

between 16.2Mt and 48.6Mt ranging between 0.15% and 0.22% WO3 at a 0.05% WO3 cut-off2

An exploration programme with extensive soil geochemistry survey targeting non-outcropping disseminated ore is being planned with the target of increasing its global Mineral Resource Estimate (MRE) along the entire Santa Comba granitic massif of 8 km x 5 km falling inside the concessions.

Managing Director Steven Turner said: "Santa Comba offers tremendous upside as demonstrated by the Exploration Target identified in 2019. Work over the last 2 years has been focused on better defining the initial open pit project in order to confirm a sizable base case operation. With the resource definition work for the feasibility study now complete, the geology team is looking at advancing the underground resource definition as part of the previously announced underground development and also seeking to reconnaissance the wider known areas of mineralisation that are evident across the granitic massif."

Rafaella Resources Limited (ASX:RFR) ("Rafaella" or "the "Company") is pleased to announce that it is currently rogressing on building a detailed 3D model of the high-gradeveins based on the JORC compliant underground Inferred

Sn (0.53% WO3 cut-off) .

All vein data from recent drilling campaigns conducted by GTT, the geological data from the ongoing detailed UG mapping, the assay data from UG stockpiles, and all available historical data from the period when COPAREX operated the underground mine, is to be incorporated into the latest version of Leapfrog GEO software. Once the 3D vein model and the in-house underground Mineral Resource Estimate (UG MRE) are available, RFR will be in a position to design additional onlybrownfield exploration drilling with the objective of increasing both the underground and open pit MRE at Santa Comba

mine.

Prior to focusing on any of the known targets (figure 3), RFR will design an extensive soil geochemistry survey, which has proved to be an excellent tool in the Iberian Peninsula for discovering greenfield non-outcropping mineral deposits, with the main target of discovering non-outcropping endogranite cupolas hosting disseminated ore.

usepersonalIn June 2019, RFR announced a near surface Exploration Target of between 16.2Mt and 48.6Mt ranging between 0.15% and 0.22% WO3 at a 0.05% WO3 cut-off4. This Exploration Target was based on the distribution of prospective rock type,

hi toric bulk sampling, historic trial mining and the Mineral Resource Estimate (MRE) of 2016, evaluated using JORC (2012) guidelines.

The current MRE of the Santa Comba deposit of 10.2Mt grading 0.18% WO3 and 162ppm Sn for 18,284t of WO3 metal content and 1,649t of Sn metal content, announced by RFR in August, 20215 is separate from the Exploration Target.

Additional Brownfield Exploration Targets

The ongoing underground detailed geological mapping conducted by GTT's geologist at the Carballeira underground Fordevelopment, located 1 km southwards from the current open pit MRE of Santa Comba, has demonstrated the presence of endogranite intrusion into schists for more than 80m in strike length (figure 3). This endogranite includes zones of disseminated ore which extends the potential for endogranite hosted disseminated ore by as much as a kilometer. Therefore, the exploration potential immediately south of the current open pit MRE is significant for both underground

narrow high-grade quartz veins and for additional open pit resources of disseminated ore.

Once underground detailed geological mapping is completed for the accessible underground development, a channel sampling program will be carried out targeting both, the zones of endogranite and the high-grade quartz veins.

Greenfield Exploration Program

In addition to the underground programme, RFR is planning to conduct a soil geochemistry survey targeting both the open pit (disseminated) and underground (high-grade quartz veins). There are many known trenches and underground works dating relating to previous artisanal mining for high-grade quartz veins trending NNE covering extensively the mining concessions (figure 4). Soil geochemistry surveying has proved to be an excellent tool for metal discoveries in the Iberian Peninsula.
