ASX ANNOUNCEMENT 2 November 2022
Alderan intersects thick gold zones in all Mizpah drill holes
HIGHLIGHTS
-
All remaining holes in Alderan’s 22-hole reverse circulation drilling programme at Mizpah intersected thick near surface gold mineralisation which remains open to the southwest.
-
Higher-grade zones within thick gold mineralised intercepts in Mizpah drill holes include:
-
7.6m @ 2.2g/t Au within 15.2m @ 1.28g/t Au from 1.5m downhole (3MZRC22-012)
-
9.1m @ 2.1g/t Au within 42.7m @ 0.76g/t Au from 18.3m downhole (3MZRC22-006)
-
7.6m @ 1.5g/t Au within 36.6m @ 0.62g/t Au from 4.6m downhole (3MZRC22-005)
-
7.6m @ 1.4g/t Au within 27.4m @ 0.56g/t Au from 33.5m downhole (3MZRC22-015)
-
10.7m @ 1.3g/t Au within 32.0m @ 0.55g/t Au from 13.7m downhole (3MZRC22-007)
-
9.1m @ 1.3g/t Au within 112.8m @ 0.38g/t Au from 22.9m downhole (3MZRC22-014)
-
7.6m @ 1.3g/t Au within 25.9m @ 0.58g/t Au from 16.8m downhole (3MZRC22-22)
-
Mizpah gold mineralisation starts from surface, gold intercepts in 15 of the 22 holes start from depths of less than 20m and the deepest intercept starts at 55m downhole.
-
The average length and grade of gold mineralised intersections across all holes is 29.5m and 0.58g/t Au with intercepts ranging from 4.6m to 112.8m in length.
-
Higher grade mineralised intervals down holes average 8.5m in length and grade 1.2g/t Au.
-
The highest grade sample interval (1.5m) is 5.23g/t Au with all holes having maximum sample grades ranging from 0.93-5.23g/t Au.
-
Depth of oxidation ranges from 3-38m across all holes with gold mineralisation occurring in oxide, mixed oxide-sulphide and sulphide zones.
-
Mizpah lies in the same rock units 2km north of the historical Drum gold mine which produced 125Koz @ 1.2g/t Au. Gold intersections in Alderan’s H1 2022 drilling at Drum include 6.5m @ 2.5g/t Au within 17.8m @ 1.7g/t Au (9DD22-003).
-
Assay results are expected over coming weeks for Alderan’s infill soil samples to better delineate high order gold-in-soil anomalies at Basin Main (assays to 0.32g/t Au) and Midway (assays to 0.19g/t Au) which lie in the same rock units 800m north and 1km south of Mizpah respectively.
-
Alderan’s next step is first pass metallurgical testwork for gold recoveries with further drilling planned pending soil and metallurgical results.

ASX ANNOUNCEMENT 2 November 2022
Alderan Resources Limited (ASX: AL8) ( Alderan or the Company ) is pleased to announce assay results for the final 16 holes in its recently completed reverse circulation ( RC ) drilling programme at its Mizpah oxide gold prospect, at the Detroit project in the Drum Mountains region of western Utah, USA.[1] The 22 hole programme (1,797m) focused on intersecting high-grade near-surface oxide gold mineralisation and demonstrating that the deposit is open down dip to the southwest (see Figure 1 and Appendix 1 for hole details). Alderan also received assay results for a redrilled hole at Drum.
In addition, Alderan has received research data on heap leach gold deposits in the USA compiled independently by CSA Global and sourced from S&P Global Capital IQ and. This data enables Alderan to internally benchmark its Detroit exploration results against producing heap leach gold mines and deposits in the scoping study to development stage.
Alderan Managing Director Scott Caithness said: “Alderan has intersected gold in all of its Mizpah reverse circulation drill holes plus demonstrated that the mineralisation is from surface and dips gently to the southwest. Gold intersections can exceed 100m in length which is significantly longer than intercepts drilled in the 1980s.
“Importantly, Mizpah could be much larger as the deposit remains open to the west and southwest, grade-thickness contouring suggests NE-SW structures may host deeper and better grade zones of mineralisation and Alderan holes drilled up to 350m west of the historical deposit have intersected thick zones of gold mineralisation.
“The Mizpah results, particularly when combined with Alderan’s Drum drilling results from Q1 2022, suggest that Detroit has potential to be a large gold district. The infill soil sample assays to better define the Basin Main and Midway gold in soil anomalies to the north and south of Mizpah could add to this potential. These assays are expected in the coming weeks.”
Mizpah Drilling Results
All holes in the Mizpah drilling programme intersected gold mineralisation (see Table 1). Alderan collected samples over five-foot (1.52m) intervals which it sent to ALS in Nevada for gold analysis. Gold grades in Alderan holes are consistent with historical drill holes however the average thickness of intersections is significantly longer than historical holes. Alderan’s strategy was to traverse the entire prospective rock sequence consisting of predominantly fine-grained siltstones and sandstones with lesser carbonates and marbles of the Tatow unit before moving into quartzites of the Lower Pioche Formation.
Gold intercepts start from surface with the deepest intercept commencing at 54.86m below surface in hole 3MZRC22-021. The average length of gold intercepts across all holes is 29.5m with intercepts ranging in length from 4.57m in hole 3MZRC22-019 to 112.78m in 3MZRC22-014.
The average grade of intercepts across all holes is 0.58g/t Au, marginally below the median grade of 0.6g/t Au for heap leach gold deposits in the CSA Global study, and intercepts commonly contain on average 8.5m thick highergrade zones, many of which grade +1.0g/t Au.
The highest gold grade for an individual sample interval (1.52m) is 5.23g/t Au which occurs in a 7.62m zone grading 2.18g/t Au from 3.05m below surface in hole 3MZRC22-012. Eighteen of the 22 holes drilled have individual sample intervals which grade +1g/t Au with the remaining holes having maximum assays in the range of 0.9-1.0g/t Au.
The gold intercepts occur in oxidised, mixed oxide-sulphide (transition) and reduced sulphide rich (un-oxidised) rocks in the same sequence of calcareous sediments as the Drum mine, 2km to the south. The depth of oxidation ranges from 3.05m to 38.10m down holes 3MZRC22-021 and 3MZRC-008 respectively.
Gold grade x thickness (GT) contouring of both Alderan and historical drill hole data indicates that the Mizpah deposit is open to the west and southwest. Alderan holes DD20M-006 and 3DD22-001 drilled 200m and 350m to the west-

ASX ANNOUNCEMENT 2 November 2022
northwest of the historical Mizpah deposit intersected 83m grading 0.41g/t Au and 69m grading 0.18g/t Au respectively. These holes suggest that the Mizpah mineralising system is significantly larger than the historically defined deposit.
GT contouring also highlights higher GT zones potentially associated with northeast-southwest trending structures which are open to the southwest. These structures have potential for thicker zones of higher-grade mineralisation.

Drum Hole Re-Drill
Alderan received assay results for hole DPRC22-001, the re-drill of historical hole YC-174 which intersected 15.4m @ 4.5g/t Au and Alderan’s hole 9DD22-007 which intersected 5.9m @ 1.2g/t Au before being abandoned.[2] Despite deviating significantly from its planned path, the hole intersected 7.62m @ 0.96g/t Au from 106.7m downhole which included 4.6m @ 1.27g/t Au. While the hole did not replicate the thickness and grade of YC-174, it clearly demonstrates that gold mineralised host stratigraphy mined in the Drum West Pit continues for at least 150m down dip to the southwest and remains open.

ASX ANNOUNCEMENT 2 November 2022
Next Steps
Alderan expects to receive assay results for the infill soil samples at Detroit in coming weeks. The C-horizon soils were collected at 40m intervals along 100m spaced infill lines and to fill in gaps in the original 200m and 400m spaced lines where anomalies have been identified. This includes 3km strike of host stratigraphy between Drum and the high order Basin Main anomaly which is 800m north of Mizpah and has gold in soil grades up to 0.32g/t Au.[3] This zone also includes the Midway gold in soil anomaly which grades up to 0.19g/t Au.
Following the receipt of all drill hole assays at Mizpah, Alderan is selecting samples for early ‘sighter’ metallurgical testing to obtain an indication of gold metallurgical recoveries. The samples will focus on mineralised intersections grading greater than 0.3g/t Au. Further drilling will be planned pending the metallurgical results.
The environmental assessment required to obtain permitting for further drilling at Drum is ongoing.
Detroit Project
The Detroit Project is one of four Alderan projects (Figure 3) 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 in relation to drilling
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. _ |
Reverse circulation drilling was used to obtain rock chip material which was then subject to gold geochemical analysis. Sample lengths were standardised at 5 feet (1.52m) meters down holes. Rock chips from the entire sample intervals were collected and despatched for analysis. Sample weights delivered to the analytical lab vary from 0.83 to 15.16 kilograms. |
| Include reference to measures taken to ensure sample representativeness and the appropriate calibration of any measurement tools or systems used. |
Reverse circulation drill chip samples were used for sampling. Sample lengths down holes were consistently 5 feet (1.52m) to provide 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 reverse circulation drill chip samples based on 5 feet (1.52m) intervals were analysed for gold 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). |
|
| 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- |

All intervals down drill holes were sampled. Sample weights ranged from 0.83 to 15.16 kilograms for individual 5ft (1.52m) sample intervals. Geologist were on site during all drilling and responsible for all logging. |
| Measures taken to maximize sample recovery and ensure representative nature of the samples. |

The Drum Mountains of west central Utah were the subject of mining and exploration for gold, copper, and manganese from the 1800’s 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 were 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 20th century, in particular, since the early 1960’s when jasperoids similar to those commonly found in highly productive gold mining districts have been identified in the Drum Mountains of Utah. Specialised studies of the jasperoids have been undertaken by USGS and the other companies over this period and 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 distal disseminated gold. The focus of Alderan’s exploration efforts at Detroit/Drum is to discover a distal disseminated gold deposit. Key features of these deposits include: 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 are: As, Sb, Ba, Te, Se, Hg f) Common argillization, development of thejasperoids and decalcification of the host rocks. |

| This mineralisation was explored, and mineralised bodies delineated in the Detroit/Drum area by the drillhole, that is presented in this announcement. Other types of mineralisation, representing exploration targets of Alderan in the Drum mountains area includes: 1. Intrusion hosted/related gold mineralisation. 2. Carlin-like mineralisation. 3. Magnetite copper-gold skarns that were identified through ground magnetics. |

| 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 Material and should be stated. |
Length weighted average was used for estimation the grade of the intersection. The sample grades within the mineralised intervals varied as follows: • 3MZRC22-007: from 0.16 to 2.62g/t Au. • 3MZRC22-008: from 0.015 to 1.395g/t Au • 3MZRC22-009: from 0.048 to 1.855g/t Au • 3MZRC22-010: from 0.08 to 2.63g/t Au • 3MZRC22-011: from 0.059 to 1.81g/t Au • 3MZRC22-012: from 0.15 to 5.23g/t Au • 3MZRC22-013: from 0.081 to 0.925g/t Au • 3MZRC22-014: from 0.039 to 4.91g/t Au • 3MZRC22-015: from 0.076 to 3.95g/t Au • 3MZRC22-016: from 0.045 to 0.95g/t Au • 3MZRC22-017: from 0.058 to 1.225g/t Au • 3MZRC22-018: from 0.162 to 1.365g/t Au • 3MZRC22-019: from 0.118 to 1.355g/t Au • 3MZRC22-020: from 0.086 to 1.93g/t Au • 3MZRC22-021: from 0.393 to 1.195g/t Au • 3MZRC22-022: from 0.08 to 2.57g/t Au • 9DRC22-001: from 0.351 to 1.405g/t Au |
| 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 intersections presented in this ASX announcement have been estimated using the length weighing method which is a standard technique broadly used in the mining industry. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
Not applicable, this ASX announcement reports the gold grade. |

| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. |
Alderan’s aim with this phase of drilling at Mizpah was to intersect near surface high grade gold mineralisation. Rock units hosting the mineralisation are interpreted to dip relatively gently at 20-30o to the southwest. Historical data including sample assays, logs and sections of reverse circulation holes drilled in the 1980s interpreted mineralisation horizons, structures and geological contacts. Alderan’s vertical drill holes are targeting the interpreted mineralised horizons and its angled holes are targeting either zones between historical drill holes or interpreted structures that have potential to host mineralisation. The true width of mineralisation has not yet been calculated and will vary from the intersections down drillholes. |
|---|---|---|
| If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. |
The unit which hosts the mineralisation is interpreted to dip gently at between 20-30o toward the southwest at an azimuth of around 220o. Holes drilled vary from vertical to -45o depending on whether they are targeting the host unit, zones between historical drillholes or interpreted structures. |
|
| 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’). |
Grade and length of mineralised intersections is estimated using nominal 0.15g/t Au as lower cut-off. The drill holes were aimed at intersecting near surface high grade gold mineralisation based on mineralised model blocks and drill intersections in historical drill holes collared during the 1980s. Given the highly variable nature of gold distribution in deposits, Alderan’s intersections are generally consistent in grade with historical holes in their vicinity however some of Alderan’s mineralisation intercepts are significantly longer in length. True width of mineralisation is not yet known and assay results for the remaining 16 holes in the Mizpah programme will enable a more accurate assessment of true width. |
|
| 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 and in the JORC Table 1. |
| 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. |
The release is focused on presenting the new drilling results verifying presence of the gold mineralisation at the historically drilled Mizpah deposit. |
17
| 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. |
Alderan rock and soil sampling has identified gold mineralisation at Mizpah and drilling in 2020 and earlier in H1,2022 confirmed presence of gold mineralisation in and around Mizpah (Refer ASX announcements dated 22 February and 22 March 2022). Alderan has also carried out magnetic and induced polarisation geophysical surveys in and around Mizpah. |
|---|---|---|
| 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 assay results are from the final 16 drill holes at Mizpah. Assays are awaited for infill soil sample assays to better define the Mizpah and other anomalies within the Detroit project area. The next phase of work includes ‘sighter’ metallurgical testwork and designing further drilling to test for lateral and down dip extensions. |
