ADDITIONAL HIGH-GRADE VEIN AND NUMEROUS TARGETS IDENTIFIED AT PROFUNDA MINE TREND

HIGHLIGHTS

• Eleven high-priority target areas identified from radiometric surveys over the 3.7 kilometre long "Profunda Mine Trend"
• Follow-up pole-dipole IP geophysical surveys totalling 6,700 line metres and magnetic surveys totalling 10,250 metres now underway over all eleven target areas
• Ground truthing of 2,000cps spot radiometric anomaly at Profunda East discovered highly mineralised dolomite under cover which assayed:
  • 37.5% Cu, 0.27% Co, 193g/t Ag and 0.14% Ni (Sample 26584)
• Similar characteristics and grade to veins and alteration sampled in wallrock peripheral to the La Profunda mine workings 1 km to the west
• Results from current geophysical surveys and sampling aim to define additional drill targets for phase two drilling programme
• Discovery of the high-grade Profunda East mineralised dolomite highlights the potential for additional undiscovered La Profunda Cu-Co-Ni sulphide bodies elsewhere in the Cármenes Project area

Riedel Resources Limited (ASX:RIE) is pleased to announce that additional high-grade assay results have been received from a sampling programme recently completed at the site of a regional radiometric anomaly at the Profunda East Prospect.

Importantly, eleven high-priority target areas have now been identified from recent radiometric surveys over the 3.7 kilometre long "Profunda Mine Trend". The most advanced of these priority targets will be further tested in the Company's near-term drilling programme.

Riedel Executive Chairman, Mr Jeffrey Moore commented:

"The discovery of strongly mineralised dolomite at shallow depth below a radiometric anomaly is highly encouraging and further validates the effectiveness of radiometric surveying in identifying multiple highly prospective exploration targets within the Cármenes project area.

Furthermore, the grade and nature of the vein sample demonstrates strong similarities to the peripheral veins sampled in wallrock at the nearby Profunda Cu-Co-Ni deposit which reinforces our theory that these regional veins may be interpreted as "pointers" to other undiscovered La Profunda Cu-Co-Ni sulphide bodies.

Importantly, eleven high-priority radiometric anomaly target areas have now been discovered over a distance of 3 kilometres along the Profunda Mine Trend with each of these targets warranting follow-up testing.

Looking ahead, we eagerly anticipate the commencement of our 5-hole diamond drilling programme at the Profunda Mine Prospect which will be undertaken concurrently with additional target generation activities."

DISCUSSION OF RESULTS

PROFUNDA MINE TREND - Radiometric Surveys and Rock-Chip Sampling

At the Profunda Mine Trend (which comprises the Profunda Mine, Profunda East and Profunda West Prospects) the Company's joint venture partner SIEMCALSA has collected 3,554 radiometric measurement points. Data is collected by using a SAIC Exploranium GR-135 Plus radiometer with a grid spacing of 25 metres by 25 metres.

Analysis and interpretation of the radiometric data has identified eleven key target areas which have been selected for follow-up exploration; including IP surveys, Ion-Leach soil geochemical surveys, detailed geological & structural mapping and diamond drilling.

The locations of the eleven Target Areas over normalised and gridded radiometric data are presented as a colour image in Figure 2.

Target Area 8

At Target Area 8 in the Profunda East Prospect, shallow excavating below a radiometric anomaly resulted in the discovery of non-outcropping, highly mineralised dolomite (see Figures 2, 3, 4 and 6) that returned outstanding assay results of 37.5% copper, 0.27% cobalt, 193g/t silver, 1.3% lead and 0.14% nickel in sample 26584 (full assay and location details in Table 1).

FIGURE 4. Rock chip sample no. 26584 at Target Area 8

The discovery of a non-outcropping mineralised vein at target Area 8 (sample 26584), which is located 1.3 kilometres to the east of La Profunda, is considered to be very encouraging.

Earlier this year SIEMCALSA selectively sampled five mineralised vein sets and zones of alteration from dolomite wallrock within the rim or edge of the previously mined La Cuevona ("the Big Cave") stope at the La Profunda Mine (see Table 1 and ASX Announcement dated 26 April 2018).

The grade and nature of vein sample 26584, including outstanding results of 37.5% Cu, 0.27% Co and 193g/t Ag shows strong similarities to the five wallrock samples collected at the Profunda sulphide breccia deposit, which enables the following conclusions to be drawn:

• The high-grade assay result from sample 26584 and oxide minerals assemblage compares very favourably with the results of alteration zone and rock-chip wallrock vein sampling carried out at La Profunda;
• The discovery of the mineralised non-outcropping vein at Target Area 8 highlights the exploration potential for the discovery of other mineralised veins, which may be present as "pointers" to other Profunda-type minerals deposits in the project area,
• Future exploration will focus on identifying other mineralised veins which might logically be expected to be associated with other non-outcropping Profunda-type Cu-Co-Ni deposits which likely exist elsewhere in the Cármenes Project area.

Target Area 2

Ground mapping over an area several hundred metres to the west of the historic Profunda Mine has also discovered copper mineralisation in rocks associated with a small historic excavation.

Rock sample 26585 was submitted for analysis at ALS Laboratories in Spain and assay results from the sample returned excellent values of 4.9% copper and 0.16% antimony.

The rock was described in the field as grey dolomite with disseminated mineralisation (bornite?). This area has been delineated as Target Area 2 (see Figure 2) and will be further investigated by follow up geophysical and geochemical test work.

NEXT STEPS

PROFUNDA MINE TREND - IP and Magnetic Geophysical Surveys

As previously advised (see ASX release dated 13 April 2018), an additional 7 PDIP (pole-dipole induced polarisation) lines, collecting data over 1,600 metres, were recently completed within

the vicinity of the Profunda Mine Prospect. Interpretation of the PDIP data identified 3 significant target clusters located within 200 metres of the historic La Profunda Mine workings.

The target clusters present compelling drilling targets and are characterised by multiple and coincident geophysical and geochemical signatures.

Based on the success of PDIP surveys at the Profunda Mine Prospect and in response to the success of recent work programmes including radiometric surveys and rock-chip sampling, ground-based PDIP and magnetic surveys have now commenced over eleven key Target Areas covering 3,000 metres of the Profunda Mine Trend to acquire data for detailed target definition and depth modelling (see Figure 7).

Within the Profunda Mine Trend, several mineralised deposit types are likely to be present and geophysical surveys aimed at better characterising disseminated-type breccia and other deposit types have been designed to provide effective ground penetration to depths of up to 150 metres.

At Profunda East, PDIP survey data will be collected over lines 5,500 metres in length and magnetic data will be collected over 8,750 metres. At Profunda West, PDIP survey data will be collected over lines 1,200 metres in length and magnetic data will be collected over 1,500 metres. The PDIP lines will be oriented east-west and north-south and the magnetic survey lines will mirror the PDIP lines but also interleaved between PDIP lines with approximately 50 metre east-west line spacing.

The geophysical programmes have been contracted to geophysical contracting and consulting company International Geophysical Technology, S.L. (IGT). IGT is domiciled in Madrid and is well placed to carry out these geophysical surveys due to its strong reputation for deliverables and experience in the field. Riedel looks forward to updating shareholders on the results of these geophysical survey programs and upon receipt of drilling approvals over the coming weeks.
