ASX ANNOUNCEMENT 30 December 2021
Alderan to focus Detroit drilling on Drum and Mizpah prospects
HIGHLIGHTS
-
Future drilling at Alderan’s Detroit Project in Utah, USA will focus on Drum Gold Mine and the neighboring Mizpah distal disseminated gold prospect.
-
Alderan’s mapping, sampling and modelling indicate Drum and Mizpah have potential for leachable oxide plus primary sulphide gold mineralisation - oxide remains open and the primary sulphide potential is untested by past exploration.
-
Alderan’s in-pit rock samples at Drum assay up to 10.7g/t gold with 36 of 76 samples assaying +0.5g/t gold and 22 assaying +1.0g/t gold.
-
Previous Alderan drilling at Mizpah includes gold mineralised intercepts up to 83m in length.
-
Modelling of historical drill data highlights strong potential for remnant mineralisation, highgrade gold in structural zones and mineralised extensions at Drum and Mizpah.
-
Drum and Mizpah have not received modern exploration since mining ceased at Drum in 1989.
-
Alderan will incorporate Drum and Mizpah drilling in its Detroit programme which recommences in January 2022.
Alderan Resources Limited (ASX: AL8) ( Alderan or the Company ) is pleased to announce it will focus future drilling on the Drum Gold Mine ( Drum ) and the Mizpah gold prospect within its Detroit Project, located in the Drum Mountains region of western Utah, USA.
Drum and Mizpah are distal disseminated gold deposits which lie only 2km apart to the southeast of the Basin porphyry. The decision to focus on Drum and Mizpah follows receipt of assays for hole 3DD21-001 and expedited sections of holes 6DD21-004 and 6DD21-005 which returned low gold grades.

Alderan Managing Director, Scott Caithness said: “Based on results to date, Alderan’s Detroit drilling programme has been successful in focusing our future exploration effort. Drum and Mizpah are both clear standout prospects with higher gold grades and potential for both oxide and primary gold deposits.
“Alderan’s modelling of 1980s drill data at Drum and Mizpah indicates combined potential for approximately 82,000 - 167,000 ounces of dominantly oxide gold mineralisation based solely on these drill holes. There is additional upside potential as both deposits remain open and neither have been explored for primary gold mineralisation below the oxide. This primary potential is indicated at Mizpah by holes ending in assays up to 9.0g/t gold and at Drum by holes drilled 150m down dip of historically mined ore which intersected up to 15m grading 4.5g/t gold.”

Detroit Drilling Update[1]
Alderan has received gold only assays for drillhole 3DD21-001 and results for the expedited sections in holes 6DD21-004 and 6DD21-005. These holes are part of Alderan’s 10-hole programme to test seven separate geochemical, geological and geophysical targets at Detroit. Gold assays received to date are low order (<0.1g/t Au) for all of samples submitted; multi-element assays, including copper, are yet to be received.

Hole 3DD21-001
Alderan designed this hole, drilled to a depth of 332.4m, to test the high amplitude 80 millisecond Southern chargeability geophysical anomaly located in close proximity to the historical Charmed gold mine. The anomaly occurs at a favourable stratigraphic contact between shales and limestone and across a west dipping fault.
1 Refer Alderan ASX announcements dated 15 October 2021, 12 November 2021, 8 December 2021.
ASX ANNOUNCEMENT 30 December 2021
The hole intersected a largely unaltered sequence of grey limestones and calcareous siltstones and shales. The source of the chargeability anomaly is interpreted to be carbonaceous shales and pyrite intersected in the top half of the hole.
Alderan submitted 242 samples including standards for multi-element analysis and gold assay results received are all low grade with the highest assay being 0.08g/t over the interval from 279.5 - 280.8m (1.3m) downhole.
Hole 6DD21-004
Drill hole 6DD21-004 was drilled to a depth of 209.4m, testing the Northern Extension chargeability anomaly for a distal disseminated gold deposit in favourable host stratigraphy and in close proximity to the Copperhead Fault. The Northern Extension chargeability anomaly has a 3D inversion model strike length of 1.1km, width of 500m and depth extent of 500m at a >20 millisecond cutoff.
The east-southeast trending Copperhead Fault is interpreted to be one of the major mineralising structures at Detroit with Alderan rock samples collected at the historical Copperhead mine grading up to 3.1% copper and 9.1g/t gold.
The hole intersected a sequence of altered calcareous shales and siltstones interbedded with limestones and dolomites. The prospective Chisholm and Tatow units were both traversed with the Chisholm intersected over a downhole length of 61m having strongly developed iron oxide clays and local silicification. The Tatow consists of a 33m length of brecciated, carbonaceous and calcareous siltstone and shale with dark fine-grained sulphide flooded bands.
A 21m length (124.6 - 145.5m downhole) of sheared, carbonaceous and strongly altered Tatow containing >10% sulphides was sampled and submitted for expedited lab analysis[2] , however gold assays are low grade. The highest assay being 0.04g/t Au over the interval from 139.4 - 140.9m (1.5m) downhole.
Hole 6DD21-005
Drill hole 6DD21-005, testing the 3D inversion modelled 900m long dumbbell shaped Copperhead chargeability anomaly (>20 milliseconds cutoff) in targeted Tatow host stratigraphy near the Copperhead fault ended at a depth of 441.07m. It traversed a similar interbedded fine grained clastic sediment and carbonate sequence as hole 6DD21-004. The prospective Tatow Formation is intersected over approximately 20m from 389m and consists of silicified, fractured and oxidised, calcareous siltstone with approximately 10% fine grained magnetite and sulphides[2] . A total of 21 samples from a 31.8m interval (396.6 - 428.4m downhole) were submitted for expedited lab analysis with the highest gold assay being 0.07g/t over the interval from 404.5 - 406.1m (1.6m) downhole.
Assays for the remaining portions of the holes are yet to be received along with assays for holes 7DD21-002 & 003 and 6DD21-006.
Drum and Mizpah Background and Next Steps
Drum Gold Mine
Alderan secured an option over the Drum Gold Mine, one of the most productive and economically important sediment-hosted gold deposits in Utah, in late September 2021 as part of its strategy to consolidate the Detroit mining district[3] . Drum was discovered in 1982 with a drill intercept of 15m grading 8.5g/t gold and was mined from the adjacent East and West pits between 1984-89 [4] . Over its six-year mine life, it reportedly produced 125,000oz of gold from 3.17 million tonnes of oxide ore grading 1.22g/t gold. Towards the end of its life, a small underground operation was developed in the West Pit which produced mined grades of +4g/t gold.

ASX ANNOUNCEMENT 30 December 2021
Alderan’s review of historical drill hole data at Drum suggests exploration potential for approximately 1.2 - 1.5 million tonnes of remnant mineralisation at an approximate grade of 1.1 - 1.4g/t gold (approximately 42,000 - 67,000 ounces)[5] . This estimate of exploration potential quantity and grade is conceptual in nature, there has been insufficient exploration to estimate Mineral Resources and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
The mineralisation remains open along strike to the south and down dip to the southwest where drill holes include YC-174 which intersected 15.2m grading 4.5g/t gold (including 6.1m at 10.3g/t Au) 150m from historical ore in the West Pit. The ore horizon mined in the East Pit remains open down dip to the southwest and has not been drill tested below the West pit. Drum has both long and high-grade historical drill intercepts with hole DM-9 having a 70.1m intercept grading 1.0g/t gold and the highest grade individual assay over a 5ft (~1.5m) sample interval being 38.8g/t gold.
Alderan composite grab rock chip sampling along the outcropping walls of the East and West pits has focussed on altered target host rocks of the Tatow and Chisholm formations which were the prime ore horizons during historical mining and in visible structural zones interpreted to be potential hosts of high-grade mineralisation. This sampling has verified the potential of Drum with the highest gold assay being 10.65g/t over a 2.8m sampling interval. Additional high-grade sample intervals include 1.7m grading 7.01g/t gold and 2.8m grading 5.86g/t gold. A total of 36 samples grade +0.5g/t gold with 22 of these grading +1.0g/t gold. An additional 17 samples grade +0.15g/t gold which is above the cutoff for oxide gold leach operations in neighbouring Nevada.
Alderan has already commenced drill site permitting so that drilling at Drum can commence in Q1, 2022 as part of its current Detroit drilling programme.

Mizpah Gold Prospect[6]
Mizpah was discovered and drilled in the mid-1980s but never mined. Alderan’s geological modelling and review of the 1980s drill data suggests that the historically delineated Mizpah oxide gold deposit has exploration potential for approximately 3.0 - 4.0Mt at an approximate grade of 0.4 - 0.8g/t gold (approximately 40,000-100,000 ounces). This estimate of exploration potential quantity and grade is conceptual in nature, there has been insufficient exploration to estimate Mineral Resources and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
Additional upside is indicated as the deposit is open along strike to the southeast and northwest and down dip to the southwest and it remains open at depth with 40 of the 197 holes drilled ending in +0.5g/t gold.
Alderan’s exploration at Mizpah has included limited verification diamond drilling, ground magnetics and induced polarization geophysical surveying plus stream, soil and rock sampling. Surface rock samples collected by Alderan grade up to 6.9g/t gold which is consistent with historical sample assays which grade in the 3-10g/t gold range.
Alderan’s diamond drill holes DD20M-002 and DD20M-005 intersected grades and widths of mineralisation (Table 1) which are consistent with historical intersections. Hole DD20M-006 suggests that the mineralisation extends to the northwest and could be much thicker than indicated in historical drill holes. It was collared 100m north-northwest of the nearest historical hole and approximately 350m northwest of the focus area of historical drilling and intersected 83m of gold mineralisation. This is significantly longer than any historical intersections.

Detroit Project
The Detroit Project is one of four projects held by Alderan (Figure 9) in 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.

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 based 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. |
|
| 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.). |
Diamond drilling was used to obtain rock materials subject to pending gold and multi-element geochemical analysis. All core was of “HQ” diameter. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
Core recoveries were measured by the geologist in charge of all logging. Core recovering for the entire program was excellent (> 98%). |
| Measures taken to maximize sample recovery and ensure representative nature of the samples. |
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 250g by a riffle splitter. The 250g sub-sample was then pulverized to 75 microns at 85% pass |
| 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-half sampling. |
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 to measure true thicknesses. The logging geologist supervised sample sawing and splitting to ensure all samples were geological representative. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
Sample weight is in the range from 3 to 7 kg which is appropriate for mineralisation present in this project. |
|
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. |
Diamond drillcore samples were assayed at the ALS laboratory. The gold method being used is the ALS procedure that uses a 30-gram charge for fire assay, AKLS code is Au-AA23 Multi-element geochemical analysis has been 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. These are standard techniques commonly used for analysis of the gold mineralisation. 4acid digest assures a most complete nature of the assayed results |
| For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. |
Not applicable. This ASX announcement reports only drilling data, portable XRF and geophysical instruments was not used. |
|
| Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
Certified standard reference materials have been inserted in the sample sequence at a rate of two percent. These materials include certified gold pulps, blank pulps, and coarse blank materials. The logging geologist was responsible for the placement of these materials. Duplicate samples will be selected and submitted for analysis once initial gold results are received. |
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
Not applicable. The current announcement is reporting essentially the initial drill holes, with initial assays still pending. |
|---|---|---|
| The use of twinned holes. | Not applicable – no twinned holes are planned at the current exploration program. Twin holes will be used after economic mineralisation has been intersected. |
|
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. |
Drillcore was rigorously documented by Alderan geologists. All field data are collected, entered into Excel spreadsheets and validated. Assay results have been obtained electronically from the ALS laboratory. Alldata are safely stored inthe company office in Perth. |
|
| 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. |

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. 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 |
| 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. No top cut was used at this stage given the relatively uniform low-grade characteristics of the mineralization. |
| 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 average grade of the intersections was estimated using length weighted method. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
Not applicable, metal equivalents not reported | |
| 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 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. | |
| 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 this ASX release. |
| 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 visual estimates and partially received assays of the drillholes drilled by the 3DD21-001, 6DD21-004 and 6DD21-005 recently drilled by Alderan at the Drum - Detroit area. The announcement includes results mostly based on the visual logging of the drill core and partially received assays |
|---|---|---|
| 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 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 once all results have been received. |
