Mineral Commodities Ltd (“MRC” or “the Company”) and its empowerment partner Blue Bantry Investments 255 (Pty) Ltd are pleased to provide an update on drilling results from Prospecting Right (WC 30/5/1/1/2/10262PR) that is also subject to an expanded mining application owned by the Company’s 50% South African subsidiary, Mineral Sands Resources (Pty) Ltd (“MSR”). The resource definition drilling is targeting the Inland Strandline areas adjacent to the existing Tormin mining operations, in the Western Cape province of South Africa.
Notable drill holes from the resource definition drilling located only 200 metres north of the current Tormin Processing Plant (all from surface) include:
-
Hole L11-11) 4m @ 61.34% THM and 7m @ 49.99% THM from 10m
-
• Hole L11-12) 5m @ 62.52% THM and 8m @ 48.50% THM from 11m • Hole L11-13) 6m @ 58.81% THM from 12m • Hole L11-8) 7m @ 43.29% THM from 9m
600 metres south of the current Tormin Processing Plant (all from surface) include:
-
Hole L6-4) 2m @ 57.41% THM from 7m
-
• Hole L6-5) 3m @ 53.11% THM from 6m

Executive Chairman Mark Caruso said, “ The drilling results are outstanding and extremely encouraging, indicating a world class heavy mineral sands deposit that demonstrates Tormin could host one of the highest grade inland mineral sands resources in the world. Based on the recent permitting approvals and these drilling results, the expansion of our world class operations at Tormin is imminent”.
In January 2020[2] , the Company received registered Prospecting Right 10262PR to explore approximately 12km in length over the Inland Strandline area covering 1741 hectares of the coastal area immediately adjacent to the existing mining operations on the Companyowned farm Geelwal Karoo 262.

Figure 1 – Prospective Inland Strandline area straddling existing processing infrastructure at Tormin
The Inland Strandline is a palaeo-marine strandline 35m above mean sea-level in an area which has undergone historical exploration since the 1930s. The historical resource work and estimates are not JORC compliant as previously reported to the ASX.[2 ] Geophysics indicate that the Inland Strandline runs contiguously along the coastline of the Company’s entire granted mining and prospecting tenure as well as areas under application.
In February 2020, the Company commenced a 7000m resource definition drilling program targeting the Inland Strandline and adjoining Northern Beaches. To date, 1971m of drilling from 121 aircore holes have been completed on the Inland Strandline with 1612 samples analysed. The drilling has been conducted with drill fence lines 250m apart on 20m spacings.
The high-grade THM mineralisation and VHM mineral assemblage observed in the laboratory results (1612 HLS and XRD analysis) of the drilling confirm the historical resource grades and are similar to the grades encountered in the first years of mining the high-grade Tormin Beach areas. The reported VHM contains high constituent zircon, rutile ilmenite, garnet assemblage as well as anatase and magnetite.

The current drilling program is targeting only 5.5km of the identified 12km long Western Strandline on Prospecting Right 10262PR. To date, drilling has intersected mineralisation across the entire strike extent of 5500m, at a width of up to 200m (Drill Fence Line 11) and to a maximum depth of 23m Strandline and Orange Feldspathic Sands Mineralisation (Hole GRC L14-9, 5-28m depth). Additional drilling planned this quarter is targeting a maiden JORC resource to an Indicated and Measured category, as well as target a newly identified Eastern Strandline.
Eastern Strandline Discovery
In addition to these outstanding drilling result, there is also substantial data reflecting the presence of multiple palaeo strandlines running semi-parallel to the coastline and within the current Inland Strand prospecting tenure. Two palaeo-marine strandlines have been identified, the known Western Inland Strandline (35m above mean sea-level) and an Eastern Inland Strandline located at an average height of 86m above mean sea level (indicated in purple in Figure 8). Historical drilling (non-JORC compliant) has reportedly intersected this strandline at a depth of 31m below surface. Aeromagnetic data clearly identifies the Eastern Strandline and the Company intends to drill the Eastern Strandline as part of the ongoing drilling program at Tormin.

Although the main target is the high grade 35m Western strandline (Figure 9), the overburden horizons above the strandline, in the form of Aeolian facies (Orange Feldspathic Sand), Erosion surface facies (Dorbank, Silcrete, Calcrete) and Red Aeolian Sands deflation zones (RAS) have also been confirmed to be mineralised. These overburden facie grades have a high variance in heavy mineral concentrations and further resource modelling is required to confirm their heavy mineral grades which is present in some drill holes from surface.

Drilling activities are scheduled to recommence in mid-April after the COVID-19 lockdown period in South Africa, targeting an Indicated and Measured JORC (2012) compliant Resource. The Company is confident that it may be in a position to release an Indicated and Measured Resource on the Inland Strand area by the end of the June Quarter.
The drilling activities at the Northern Beaches are ongoing with results also expected in this coming quarter.
Drill collar locations from completed exploration holes to date are outlined in Appendix 2.

Cautionary Statement
This report contains certain forward-looking statements. Any forward-looking statements reflect management’s current beliefs based on information currently available to management and are based on what management believes to be reasonable assumptions. It should be noted that several factors could cause actual results or expectations to differ materially from the results expressed or implied in the forward-looking statements.
Competent Persons Statement
The information in this Announcement related to Exploration Results is based on information compiled and has been approved for release by Mr Bahman Rashidi, who is a member of the Australian Institute of Mining and Metallurgy (AusIMM) and the Australian Institute of Geoscientists (AIG). Mr Rashidi is Exploration Manager and a full-time employee of the Company and has over 22 years’ of exploration and mining experience in a variety of mineral deposits and styles. Mr Rashidi has sufficient experience which is relevant to the style of mineralisation and types of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person in accordance with the JORC Code 2012.
The information from Mr Bahman Rashidi was prepared under the JORC Code (2012). Mr Rashidi consents to the inclusion in the report of the matters based on this information in the form and context in which it appears.
The following table provides a summary of important assessment and reporting criteria used for the Tormin Operation in accordance with the Table 1 checklist in The Australian Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves (The JORC Code, 2012 Edition). Criteria in each section apply to all preceding and succeeding sections.

Appendix1 JORC TABLE 1
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections)
| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| • Sampling techniques |
• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section)
| Criteria | Explanation | Commentary |
|---|---|---|
| • Mineral tenement and land tenure status |
• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
• The area has a granted prospecting right (WC 30/5/1/1/2/10262 PR) in the name of Mineral Sands Resources (Pty) Ltd a subsidiary of ASX listed Mineral Commodities Ltd (ASX: MRC). • This prospecting Right (Inland Strand) incorporates an area approximately 12km in length covering 1741 hectares of coastal area immediately adjacent to the existing mining operations on the Company-owned farm Geelwal Karoo 262. |
| • Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. | • The general area has been investigated and mined for heavy mineral deposits as far back as the 1930s (Haughton, 1931). Subsequent geological surveys and exploration programs investigated the distribution, mineralogy and economic potential of the heavy mineral sands along the coastline of Geelwal Karoo (Toerien & Groeneveld 1957, Abele 1989, Swart 1990, Barnes 1998) and Trans Hex 1989-1991). • During 1999, Trans Hex conducted additional onshore drilling of strandlines and identified the inland raised beach deposits containing heavy minerals. Trans Hex subsequently bulk sampled the material by digging several trenches in 1999-2000. |
| • Geology | • Deposit type, geological setting and style of mineralisation. | • The heavy mineral sand deposits occur in a current active beach environment (e.g. Tormin mine) as well as in older palaeo-beach raised strandlines found inland (inland strandlines) eg. Tronox Namakwa Sands. • Apart from the mid-Jurassic, Cretaceous and Tertiary (Paleogene) sediments along the coast, numerous small fossiliferous, marine and terrestrial deposits of Neogene age outcrop along the coastal zone. • The Neogene deposits are host to the commercially important diamondiferous and HMS raised beach terraces. |
| • Drill hole Information |
• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: • Easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
• A summary of the 121 aircore drilling (1971 m) is reflected in the text of this release. • The minimum hole length is 3m, maximum 36m and average depth of drilling is 16.28 metres. • East collar ranges – 222,151mE to 225,480mE • North collar ranges – 6,503,989mN to 6,508,430mN • Azimuth ranges/ Dip ranges – vertical drilling |
| • Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• No weighting or cutting of HM values, other than averaging of grades intersected were reported. • As all samples are 1 metre in length, no length weighting is required in averaging grades. |
| • Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
• The strandline mineralisation is sub-horizon in nature and the air core drilling intercepts are vertical. • Thickness of intercept reported is therefore true thickness of the mineralisation. |
| Criteria | Explanation | Commentary |
|---|---|---|
| • Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• Maps, sections and plan view are provided in this report. |
| • Balanced reporting |
• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
• Intersection with grades above 10% THM (Total Heavy Minerals) or above 5% VHM (Valuable Heavy Minerals) have been reported in this release to indicate the high-grade strandline zones. |
| • Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• Historical drill data is not reported as it is classified as historical foreign estimates that are non-JORC compliant. |
| • Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
• 81% of current drilling lab results have been received to date. • Only 33% of the planned 6000m of drilling has been completed to date. • Further drilling is planned to produce an indicated and measured resource over the Western Inland Strandline and an inferred Resource over the Eastern Inland Strandline. • The drilling activities in the Northern Beaches is ongoing, targeting Indicated Resource. |
