Significant Rare Earth Results from Drilling and Rock Chip Sampling at Khartoum Project
Highlights:
-
Recent assessment of results from rock chip sampling and RC drilling previously completed by the Company at the Khartoum Project, North Queensland, has identified significant Total Rare Earth Oxide (TREO) values including:
-
Rock chip values to 6993ppm and 5782ppm TREO.
-
Drilling results of 8m at 2096ppm and 2m at 3093ppm TREO.
-
High ratio of Heavy REO including 62% (with 1680ppm Y203) and 81% (with 2310ppm Y203).
-
High ratio of Magnetic REO with 15 samples greater than 20%.
-
Significant values to 1230ppm Nd2O3, 456ppm Dy2O3, 377ppm Pr6O11, 54ppm Tb4O7, 218ppm Gd2O3, and 2310ppm Y203.
-
Elevated REE samples collected in areas of significant Sn and W sample results, from 5 different prospect areas.
EV Resources Limited (ASX:EVR) (“ EVR ”, or the “ Company ”), is pleased to provide an exploration update for the Khartoum Project, located in North Queensland.
A recent assessment of rock chip and drill samples has identified several prospect areas that have returned significant Rare Earth Element (REE) results. The samples were initially collected during the Company’s exploration efforts to define tin (Sn) and Tungsten (W) mineralisation.
Rock chip samples were collected from various prospects within EVR’s Khartoum tenure, either from historic mine dumps or outcropping geology that indicated potential for Sn and/or W mineralisation. The drill samples are from RC drilling completed by EVR during 2022 to test Sn geochemistry targets.
Drilling was undertaken in the Boulder area to test the significance of surficial Sn geochemical anomalies in areas of greisen alteration of host granites. The drilling intersected elevated REE at shallow depth at a few locations (see Table 2 for a summary of significant REE results). Most of the intersections returned a high ratio of Magnetic REO with maximum values of 223ppm Dy2O3, 1052ppm Nd2O3, 233 Pr6O11 and 39ppm Tb4O7. Many of the drill results are from 4m composite samples, hence grades may be greater over individual metre intervals.

EV Resources’ Executive Director Adrian Paul commented:
“The Herberton-Mt Garnet Mineral Field has always been recognised as a highly mineralised, prospective and under-explored region. Recent studies by the Queensland Geological Survey has highlighted the district, including EV Resources Khartoum Project tenure, as having potential to host epithermal, intrusive-style and porphyry-style mineralisation. Work by the Company in the past 18 months since acquiring the tenements has defined several areas with potential for economic Sn and W mineralisation, with one prospect having already been tested with preliminary drilling. The presence of significant Rare Earth Element values, and particularly critical NdPr magnet REEs, highlights the potential of the Khartoum Project to host critical metals.”

The most significant REE rock chip results are from areas of highly altered and greisenised fractionated granite outcrop. These include samples returning Total Rare Earth Oxide (TREO) values of (See Table 1 for a summary of elevated REE results):
-
Adelaide - 3920ppm TREO (1680ppm Y203, 323ppm Nd2O3, 305ppm Dy2O3 and 47ppm Tb4O7).
-
Gows - 3295ppm TREO (675ppm Nd2O3, 83ppm Dy2O3, 155ppm Pr6O11 and 15ppm Tb4O7).
-
Fingertown - 4678ppmTREO (2310ppm Y203, 151ppm Nd2O3, 456ppm Dy2O3 and 54ppm Tb4O7).
-
Geebung - 6993ppm TREO (1230ppm Nd2O3, 377ppm Pr6O11, 99ppm Dy2O3 and 20ppm Tb4O7) from Geebung.
It should be noted that the REE results are from samples that were collected during exploration for Sn/W and were not targeting REE mineralisation, hence the significance of the elevated REE values. Also of note is that there are no significant REE values in the immediate areas of drilling, indicating surface depletion of REE elements, or the presence of lithological units intersected in drilling that do not have a surface expression.
Data collected to date has been assessed at a high-level by a Brisbane-based Geological Consultancy, who noted that the level of TREO anomalism does potentially indicate a broader mineral system which warrants further investigation. It should be noted that although highly anomalous, the values are an order of magnitude lower than typical hard rock primary REE deposits.
EVR recognisies considerable upside considering no work has been undertaken specifically targeting REE mineralisation at the Khartoum Project and of over 5000 rock chip samples in the geochemistry database less than 500 (EVR samples) have been analysed for a full suite of REE elements. Although drilling is sparce throughout the Khartoum tenure, only the holes completed by EVR in the Boulder area have been analysed for REE elements. Hence, the anomalous REE areas are heavily skewed towards prospects that have been sampled by EVR.
Further work is required to determine the significance and potential of the REE values. Host mineralogy is not yet understood and will be a key factor in determining the metallurgical process required to extract REEs and to what extent REEs could contribute to the Khartoum Project’s economic potential.

JORC Code, 2012 Edition – Table 1 report
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | Explanation | Commentary |
|---|---|---|
| Sampling techniques | • Nature and quality of sampling (e.g. 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 (e.g. ‘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 (e.g. submarine nodules) may warrant disclosure of detailed information. |
Rock chip samples of selected zones of outcrop or mullock from workings were collected based on geological determination. Bulk RC drill samples were collected at one metre intervals and riffle spilt to a 87.5:12.5 ratio. Initial 4m composite samples were collected by spear sampling consecutive bulk bags to provide composite samples. Where significant assay values were returned, 1m riffle spilt samples were submitted to the laboratory to provide a result more indicative of in situ mineralisation. All samples were between 2-3kg and were individually labelled and geologically documented. |
| Drilling techniques | • Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). |
Drill type was face sampling hammer reverse circulation using a 140mm bit.. |

| Commentary The recovery and moisture content of each 1m drill sample sample was visually assessed and recorded. A high-capacity rig with auxiliary booster was used to ensure sufficient air capacity to maintain dry samples. Cyclone and splitter were cleaned at every rod change and after every hole. There is no apparent relationship between sample recovery and grade. Geology of rock chip samples was recorded. Geological records have primarily been quantitative. All RC samples were geologically logged by a qualified geologist at one metre intervals as each hole was drilled. Data captured included lithology, oxidation state, mineralogy and alteration. Both qualitative and quantitative data was collected. RC chips were retained in trays for future reference. All holes for their entire length were logged. For RC drilling each individual one metre sample of approximately 30kg is passed through a cyclone into a rotary cone splitter. Approximately 87.5% was collected in a large plastic bag which is retained for future use if required. The 12.5% split was collected a separate calico bag from the cone splitter. All samples were tube (spear) sampled to provide 4m composite samples. 4m composite samples were initially submitted to the laboratory. 1m samples corresponding to significant 4m composite results were then submitted to the laboratory. At the laboratory, samples were dried crushed and pulverised to 85% passing 75 microns. This is considered to appropriately homogenise the sample to allow subsampling for the various assay techniques. No Certified Reference Material, duplicate samples or blanks were used. Sample sizes are industry standard and considered appropriate. |

Both qualitative and quantitative data was collected. RC chips were retained in trays for future reference. All holes for their entire length were logged. |

• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including |
For RC drilling each individual one metre sample of approximately 30kg is passed through a cyclone into a rotary cone splitter. Approximately 87.5% was collected in a large plastic bag which is retained for future use if required. The 12.5% split was collected a separate calico bag from the cone splitter. All samples were tube (spear) sampled to provide 4m composite samples. 4m composite samples were initially submitted to the laboratory. 1m samples corresponding to significant 4m composite results were then submitted to the laboratory. At the laboratory, samples were dried crushed and pulverised to 85% passing 75 microns. This is considered to appropriately homogenise the sample to allow subsampling for the various assay techniques. No Certified Reference Material, duplicate samples or blanks were used. Sample sizes are industry standard and considered appropriate. |

The holes were designed to intersect mineralisation at a near-perpendicular orientation based on surface outcrop mapping, however true width of intersections cannot be determined at this stage. A drill hole location plan is included as Figure 2. As drilling was of an initial exploratory nature, with only a small number of holes drilled at each location, drill hole sections are not deemed necessary at this stage.

Exploration within the Khartoum Project tenements is at an early stage. EV intends to undertake more systematic, detailed exploration work over higher-priority targets, including mapping and channel sampling along the extent of outcrop that has previously returned elevated results. If the results of rock chip values is of sufficient grade and extent of outcropping target is deemed significant, further appraisal of prospects will be by drilling. Further drilling is being planned to follow up the significant zones of mineralisation intersected in drilling. |

| 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 (e.g. ‘down hole length, true width not known’). |
Calculated intersections are based on down hole length, true width is not known. The holes were designed to intersect mineralisation at a near-perpendicular orientation based on surface outcrop mapping, however true width of intersections cannot be determined at this stage. |
|
| 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. |
A drill hole location plan is included as Figure 2. As drilling was of an initial exploratory nature, with only a small number of holes drilled at each location, drill hole sections are not deemed necessary at this stage. |
|
| 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. |
All results above the cut off reporting value of 1000ppm TREO have been reported. | |
| 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. |
All meaningful & material exploration data has been reported. | |
| Further work | • The nature and scale of planned further work (e.g. 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. |
Exploration within the Khartoum Project tenements is at an early stage. EV intends to undertake more systematic, detailed exploration work over higher-priority targets, including mapping and channel sampling along the extent of outcrop that has previously returned elevated results. If the results of rock chip values is of sufficient grade and extent of outcropping target is deemed significant, further appraisal of prospects will be by drilling. Further drilling is being planned to follow up the significant zones of mineralisation intersected in drilling. |
