ASX ANNOUNCEMENT 12 November 2021
Alderan drilling at Detroit on track – first two holes complete
HIGHLIGHTS
-
Alderan completes the first two holes in a planned 10-hole (~3,000m) drilling programme at its Detroit copper gold project, Utah, USA.
-
Hole 3DD21-001 testing the Southern chargeability anomaly intersected a sequence of limestones and calcareous fine-grained sediments containing up to 10% pyrite.
-
Samples from hole 3DD21-001 submitted for analysis with assays expected in January 2022.
-
Hole 7DD21-003 testing the Basin Main magnetic anomaly intersected veined and altered diorite and porphyry containing disseminated magnetite zones and up to 10% sulphides consisting of pyrite, minor molybdenite and lesser chalcopyrite.
-
Samples from hole 7DD21-003 due for despatch over the coming week.
-
Drilling commenced on Site E in the Copperhead area to test the Northern Extension chargeability anomaly close to the Copperhead Fault, historical mine workings and highly anomalous rock samples.
Alderan Resources Limited (ASX: AL8) ( Alderan or the Company ) is pleased to announce progress on its 10hole (~3,000m) drill programme at its Detroit Project located in the Drum Mountains region of western Utah, USA[1] .
The first two holes in the programme testing geophysical targets were drilled to their planned depths. The first hole, 3DD21-001, testing the Southern chargeability anomaly was drilled to a depth of 332.4m while hole 7DD21003 testing the Basin Main magnetic anomaly reached a final depth of 513.07m.
The drill rig has now moved to site E in the Copperhead area to test the Northern Extension chargeability anomaly. The site is located in favourable host stratigraphy in close proximity to the Copperhead fault zone and Alderan rock samples immediately to the west assayed up to 3.2% copper and 9.1g/t gold. Four holes are planned in the Copperhead-Northern Extension area.
Alderan Managing Director Scott Caithness said:
“Drilling at Detroit is progressing well with good daily meterage rates being achieved by the Major Drilling team. The first hole testing the Southern chargeability anomaly intersected a sequence of limestones and calcareous fine grained sediments. The source of the chargeability anomaly is believed to be carbonaceous and pyritic sediments intersected in the top 150m of the hole.
Hole 7DD21-003 into the Basin Main magnetic anomaly has intersected veined, fractured and altered diorite and porphyry which contains pyrite and minor visible molybdenum mineralisation. Lesser chalcopyrite has also been observed in places down the hole.
Samples are being progressively submitted for lab analysis with initial assays expected in January 2022.”
Detroit Drilling Programme – Current Status
Alderan contracted Major Drilling, one of the world’s leading drilling companies, to complete a 10-hole (~3,000m) diamond drilling programme at the Basin Complex in its Detroit project after surface exploration identified multiple targets with potential for copper and gold deposits.

ASX ANNOUNCEMENT 12 November 2021
Drilling aims to intersect copper and gold grades with the long term aim of defining a mineral resource at the Basin Complex. The targets are associated with magnetic and chargeability IP geophysical anomalies, favourable host rocks, known copper and gold mineralisation and potentially mineralised structures. Figure 3 shows the location of the drill sites and Table 1 provides a summary of the location, hole orientation and target rationale for the holes.
Drill hole 3DD21-001 testing the Southern chargeability anomaly distal disseminated gold target was completed at its target depth of 332.4m. The hole intersected a sequence of grey limestones and fine-grained calcareous sediments. The chargeability anomaly is interpreted to be caused by fine disseminated pyrite in a more carbonaceous shale unit in the top 150m of the hole. The hole is locally fractured and dissolution cavities occur in limestone.
Drill hole 7DD21-002 testing the Basin Main magnetic anomaly porphyry copper-gold-molybdenum target was abandoned due to drilling difficulties and hole 7DD21-003 was the re-drill from the same site. This hole traversed potassic, siliceous and sericite altered diorite and porphyry intrusives consistent with rocks in porphyry deposits to its final depth of 513.07m (see Figures 1 & 2). Quartz veins, veinlets and stockworking occurs throughout the hole. Pyrite content ranges up to 10% occurring in veinlets and stockworks. Minor molybdenum and lesser chalcopyrite were observed locally down the hole.
In relation to the disclosure of visual mineralisation, the Company cautions that visual estimates of mineralisation should never be considered a proxy or substitute for laboratory analysis. Laboratory assay results are required to determine the widths and grade of the visible mineralisation reported in preliminary geological logging. The Company will update the market when laboratory analytical results become available.

ASX ANNOUNCEMENT 12 November 2021
Samples from hole 7DD21-001 were delivered to the ALS laboratory in Nevada for analysis. Sampling of hole 7DD21-003 is expected to be completed in the next week ahead of despatch to the lab. Assay turnaround times are currently around eight weeks hence results are now expected in January 2022.
The drill rig has moved to the Copperhead area where it is drilling proposed hole E to test the Northern Extension chargeability anomaly near the Copperhead fault zone at the contact between favourable Lower Cambrian Pioche and overlying Tatow units. The Tatow unit is known to host gold mineralisation at the Drum Gold Mine and at Mizpah to the southeast. Four holes are planned in the Copperhead area - two holes testing the Northern Extension and two testing the Copperhead chargeability targets in close proximity to the Copperhead Fault. Copperhead is an historical gold and copper mine and Alderan rock sampling has returned assays of up to 3.2% copper and 9.1g/t gold.

Detroit Project[2]
The Detroit Project is one of four projects held by Alderan (see Figure 4) in the state of Utah, USA. It lies within the Detroit Mining District, approximately 175km southwest of Salt Lake City, and contains numerous historical copper, gold and manganese mines. The district has been explored for copper and gold in the past by major mining companies such as Anaconda Copper, Kennecott, Newmont, BHP and Freeport-McMoRan but no one company was able to build a significant contiguous land position to enable district-wide modern exploration. The United States Geological Survey ( USGS ) has also explored the area, sampling extensive mineralised jasperoids.
Alderan has a consolidated exploration area at Detroit of 25.5km[2] through a series of option agreements with tenement owners. This provides the Company with the opportunity to conduct the first ever modern exploration over the entire mining district.
Prior to consolidation, Alderan completed a seven-hole drilling program in and around the Mizpah prospect with hole locations guided by tenement holdings. Post consolidation, Alderan has compiled past exploration data, completed stream sediment, rock and soil sampling, conducted ground magnetics and induced polarization geophysical surveys, carried out petrographic examinations of drill core and modelled the historical Mizpah oxide gold deposit. It has also secured and option to acquire the Drum Gold Mine, one of Utah’s largest historical gold producers.
Alderan’s exploration to date has highlighted Detroit’s potential to host porphyry copper-gold-molybdenum plus distal disseminated, skarn and structure related gold deposits.

Appendix 2: JORC Code, 2012 Edition – Table 1 Report
Section 1 - Sampling Techniques and Data
(Criterial in this section apply to all succeeding sections)
| Criteria of JORC Code 2012 |
JORC Code (2012) explanation | Details of the Reported Project |
|---|---|---|
| Sampling techniques |
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialized 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. |
Diamond drilling was used to obtain rock materials subject to pending gold and multi-element geochemical analysis. Sample widths vary from 1 to 3 meters dependent on observed geologic characteristics. The core was sawn or split in equal halves ensuring that geologic characteristics were represented equally in both the analytical sample and archive materials. Sample weights delivered to the analytical lab vary from 4 to 14 kilograms in weight. |
| Include reference to measures taken to ensure sample representativeness and the appropriate calibration of any measurement tools or systems _used. _ |
HQ diameter drillcore was used for sampling. Sample length was 1 to 3 metres, that provides good representative material. |
|
| 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. |
The drillcore samples are analysed for gold and multi-element geochemistry. Individual samples were selected base on their geological characteristics including lithology, alteration, and mineralization styles. Materials are being analysed at ALS North American facilities. The gold method being used is the ALS procedure that uses a 30-gram charge for fire assay (Au- AA23). Multi-element geochemical analysis will be completed on geologic composite that vary in width from 4 to 6 meters that development from remaining gold sample pulps. That ALS procedure for this is ME-MS61m. |

Industry standard practices, e.g. optimized drilling speed and regular changes of the drill bits, were used throughout to ensure no recovery or sample representation issues were encountered. |
|
| Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
Not relationships observed between the core recovery and sample grades. | |
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. |
Geological, geotechnical, and geophysical (magnetic susceptibility) logging was completed on all of the core materials and is to an industry standard appropriate to the initial exploration nature of the program. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. |
Geologic logging is qualitative to semi-quantitative making use of an experienced geologist and high-quality binocular microscope. Geotechnical and geophysical logging results are quantitative. |
|
| The total length and percentage of the relevant intersections logged. |
100% of the drill core was logged applying the same logging and documentation principles. | |
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken |
Drill core was sawn by a diamond saw and half core was sampled with remaining half core retained in the core trays. |
| If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. |
Not applicable, diamond drill core drilling was used. | |
| For all sample types, the nature, quality, and appropriateness of the sample preparation technique. |
The samples are prepared in the ALS laboratory in USA. Sample preparation follows the standard procedure of the ALS lab, representing the industry common practice. Each sample was weighed, fine crushed to <2mm (70% pass) and split by a riffle splitter. The sample was then pulverized up to 250g at 85% < 75um. |

==> picture [309 x 142] intentionally omitted <==
| Quality control procedures adopted for all sub- sampling stages to maximise representativeness of samples. |
The logging geologist supervised sample sawing and splitting to ensure all samples were geological representative. Quality of comminutions is verified by a control sieving, which is a standard procedure of the ALS laboratories. |
|
| Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-halfsampling. |
The diamond drill holes were oriented and drilled in such a way to attempt to cut inferred geologic controls (bedding, faults etc.) perpendicular to their strike in order to measure true thicknesses. The logging geologist supervised sample sawing and splitting to ensure all samples were geological representative. |

|
| Discuss any adjustment to assay data. | Not applicable – no adjustments made. | |
| Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. |
A handheld sub-meter GPS was used for collars and geochemical samples locating. Accuracy of the GPS based techniques was deemed sufficient given the initial exploration nature of the drill program. |
| Specification of the grid system used. | All data are recorded in a UTM zone 12 (North) NAD83 grid. | |
| Quality and adequacy of topographic control. | RL values obtained by GPS were routinely compared with the nominal elevation values that were deduced form the regional topographic datasets. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. | Location and spatial distribution of the drillholes are applicable for assessment of a prospectivity of the project area but the data not suitable and was not intended to be used for quantitative assessments of the project, i.e. not intended for estimation of the Mineral Resources. |

Acknowledgment and appraisal of exploration by other parties. |
The Drum Mountains of west central Utah have long been a subject of mining and exploration for gold, copper, and manganese, starting from 1800’s and continued until early 1900’s. This was followed by renewed interest in beryllium, gold, manganese, and uranium in the past 20 years. Gold and copper were discovered in the Drum Mountains in 1872, and from 1904 to 1917, gold, silver, and copper was produced from siliceous replacement fissure deposits in jasperoids, limestone and dolomite, for a total value of about $46,000. Exploration for gold and base metals intermittently continued through the entire 20’s century. In particular, since early 1960’s, when jasperoids similar to that commonly found in highly productive gold mining districts have been identified in the Drum Mountains of Utah, the specialised studies of the jasperoids have been undertaken by USGS and the different mining companies. Sampling of these rocks commonly reveals anomalous concentrations of gold. |
| Geology | Deposit type, geological setting, and style of mineralisation. |
The mineralisation presented at the Drum area includes different types and mineralisation styles, main of which are Carlin-like gold, gold-bearing skarns, Cu-Mo-Au porphyries, and Marigold-type. The focus of Alderan’s exploration efforts at Detroit is to discover a Carlin-like gold deposit. Key feature of Carlin-like deposits includes: a) Favorable permeable reactive rocks (silty limestones and limey siltstones) b) Favorable structures often coincident with mineral-related intrusive c) Gold-bearing hydrothermal solutions |
12
| d) Micron-sized gold in fine-grained disseminated pyrite e) Common geochemical indicators As, Sb, Ba, Te, Se, Hg f) Common argillization and jasperoids; fairly common decalcification. Other types of mineralisation, representing exploration targets of Alderan in the Drum mountains area includes: 1. Intrusion hosted/related gold mineralisation positions. 2. Marigold style brecciated quartzites, which can spatially associate with the Carlin-like mineralisation. 3. Magnetite copper-gold skarns that were identified through the ground magnetics. |

| 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: |
The drillhole information presented in the releases is adequately reported in the summary table shown at Appendix 1. |
| 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_and_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. |
The drillhole information presented in the releases is adequately reported in the summary table shown at Appendix 1. | |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually |
Length weighted average was used for estimation the grade of the intersection. The samples grade of the mineralised interval varied from 0.04 to 1.15 g/t. No top cut was used at this stage given the relatively uniform low-grade characteristics of the mineralization. |
13
| 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. |
Not applicable. This ASX announcement reports assays obtained for part of the drillholes. The data at this stage of exploration are insufficient for analysis relationships between thickness and grade of mineralisation. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
Not applicable, this ASX announcement reports the gold grade of a single intersections. | |
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. |
The diamond drill holes were oriented and drilled in such a way to attempt to cut inferred geologic controls (bedding, faults etc.) perpendicular to their strike in order to measure true thicknesses. |
| If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. |
True width of mineralisation is not known. | |
| 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’). |
True width of mineralisation is not known. However, because the drilling was oriented approximately perpendicular to the strike of the exploration targets it is assumed that reported intersections of pyrite mineralised intervals are closely approximate their true thickness. |
|
| 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 and tables are presented in the text of the release. |
14
| 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 new results are presented in the release and summarised in the tables and presented on the maps. These include results of the drillholes drilled by theDD20M-001 - DD20M-007recently drilled by Alderan at the Drum - Detroit area. The announcement includes results of the visual logging of the drill core and the gold assay which are summarized and reported concisely. |
|---|---|---|
| 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. |
The rock-chips geochemical survey results have been presented on the previous announcements of the Alderan. |
| 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. |
The next phase of exploration is currently planned and will be announced separately. |
