High definition induced polarisation and electromagnetic survey commenced
==> picture [157 x 5] intentionally omitted <==
The Board of Alderan Resources Limited (“Alderan”) (ASX: AL8) is pleased to announce that exploration work has commenced on the Frisco Project in Utah, USA, with geophysics crews starting an induced polarisation (“IP”) and electromagnetic (“EM”) survey. A drilling contract has also been executed with drilling expected to commence in late July/early August.
Alderan has engaged Dias Geophysics to conduct a high definition IP survey over the entire Frisco Project (24.77km[2] ), and an EM survey over the Accrington copper-zinc skarn prospect. Geophysics crews have been mobilised and have arrived at site.
The IP survey is designed to complement existing datasets and to assist in the definition of current and new targets. The EM survey is to be conducted over the large Accrington skarn prospect with the objective to identify conductive bodies that may represent massive sulphide bodies. It is expected that both the surveys will be completed within 6-8 weeks.

Cactus Cu-Au-Ag Breccia Pipes
The Cactus project is composed of at least three hydrothermal breccia pipes including the historic Cactus coppergold-silver mine which will be the focus of initial drilling. Mineralisation is hosted within a series of outcropping quartztourmaline-chalcopyrite-pyrite breccia pipes which are aligned along a west-northwest trending structural corridor some 1,000m long by up to 400m wide.
The Cactus pipe was mined across over 200m in strike, up to 55m in width and to approximately 275m below surface with mineralisation remaining open along strike and at depth. Major mining activities stopped in 1915 at the southeastern boundary of the claim when the neighbouring claim holder started legal proceedings. Alderan holds the rights to all adjoining claims. Despite the historical mining, significant mineralisation remains within the breccia pipe. Historical drilling at the Cactus Breccia Pipe returned significant copper-gold-silver mineralisation as shown in Table 1.

Historical drilling did not commonly assay for gold and silver, despite the mine being a historical copper-gold-silver producer. Alderan intends to conduct infill and extensional drilling with an aim to establish an initial JORC compliant resource at Cactus. Drilling will also test the continuity of mineralisation at depth and along strike between the Cactus and Comet/New Year breccia pipes. The Comet and New Year breccia pipes have had limited exploration comprising mostly of shallow drilling. At Comet, historical shallow drilling intersected copper-gold-silver mineralisation to end of hole. Magnetic data indicate that the Comet breccia pipe may be of similar size to the Cactus pipe and that mineralisation may be continuous between these pipes. Limited drilling at the New Year pipe intersected significant copper, however drilling was restricted to drilling down dip of outcropping breccia.

All breccia pipes are hosted within strongly magnetic Cactus - Monzodiorite and appear as distinct magnetic lows within Alderan’s airborne magnetic survey (see Figures 6 & 8). Demagnetisation is caused by hydrothermal alteration and replacement of host rock with non-magnetic breccia material during emplacement. 3D inversion modelling of magnetic data shows a deep downward continuation of these demagnetised zones (Figure 6) in direct spatial correlation with breccia mineralisation outcropping and underground, indicating a potential coalescence of breccias at depth.

The Cactus Breccia Pipes are interpreted to have been formed within the context of an underlying mineralised porphyry intrusion (the Cactus Canyon prospect). Deep historical drilling (AMAX hole 520-1), located in between the Cactus and New Year breccia pipes, intersected an interval containing mineralised porphyry assaying 30.48m @ 0.22% Cu (from 426.72 to 457.20m). Gold was not assayed. This intersection is spatially associated with the modelled zone of low magnetisation, highlighting the potential significance of this exploration target. Porphyritic rocks are often found as clasts within the breccia, material at surface and within the old mine dumps that have been mapped in outcrop adjacent to breccia pipes.

About the Cactus Canyon Cu-Mo-Au Porphyry System
Porphyry copper deposits account for the majority of the world’s copper production and are often large, world class, long life mines. These intrusive systems often result in the emplacement of several associated deposits types including proximal skarns, breccia pipes, mantos and epithermal gold deposits.
Work undertaken by Alderan has confirmed the presence of a large central porphyry system at the heart of the Frisco Project which has been named the Cactus Canyon prospect. The Company believes that the Cactus Breccia Pipes form part of the wider Cactus Canyon porphyry system, which also incorporates the Accrington and Horn Cu-Zn-PbAg skarns.
Key features of the system include:
-
A large central magnetic anomaly up to 2km in diameter located below and adjacent to the Cactus Breccia Pipes;
-
Numerous outcropping and often copper bearing intrusive porphyritic dikes with historical drilling also intersecting copper-molybdenum bearing dikes adjacent to the central Cactus Canyon target;
-
at least 5 individual porphyry intrusive phases identified to date, ranging from mafic to felsic in composition;
-
• the presence of mineralised breccia pipes and large skarns, which typically form contemporaneously and proximal to underlying porphyry intrusions;
-
regional scale alteration typical of porphyry intrusives; and
-
large scale geochemical zonation across the entire Frisco Project with distal gold-silver anomalism, trending to more proximal zinc-lead and central copper-molybdenum dominant anomalism - a key signature of many porphyry deposits in the world.
The induced polarisation being undertaken by the Company will cover the entirety of the Frisco Project and it is hoped it will provide further evidence of widescale mineralised exploration targets at Cactus Canyon, Cactus and Accrington.

About Alderan Resources Limited
Alderan is a mineral exploration Company with a focus on the Frisco Project, located in Utah, United States of America. The Frisco Project encompasses an area of significant historical mining activity with numerous old mines and workings across an area of approximately 7km by 4km. These include:
-
the Cactus copper-gold-silver deposit and breccia pipe, one of several mineralised breccia pipes over an area of approximately 1000 metres by 400 metres. Modelling of magnetic survey data demonstrates that these pipes are likely connected at depth;
-
the Accrington copper-zinc-silver-gold skarn, which hosts extensive mineralisation across an area of 1.8 kilometres by 1.2 kilometres; and
-
the Horn zinc deposit, a historic lead-silver mine, which contains significant amounts of unmined high grade zinc.
The Company believes that these three deposits are genetically related to, and were formed contemporaneously with, underlying mineralised (copper-molybdenum-gold) porphyry intrusions. Work undertaken by the Company has confirmed the presence of a mineralised porphyry system beneath and adjacent to the Cactus breccia pipes.

APPENDIX 1
JORC Code, 2012 Edition – Table 1 Report
Cactus Prospect
Section 1 - Sampling Techniques and Data
| 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. |
• Sampling of core was generally of 5 feet or 10 feet over mineralised intervals in the historic drilling, no duplicates, standards or blanks are known. • Select intervals were used for minor core sections and composite samples. • Sample weight of historic sampling is unknown. • Alderan resampling of Amex exploration inc (“Amex”) drillholes 520-4 Assays completed at ALS Labs Reno Nevada - no standards/blanks - 9 ft composite sample interval of section 575ft - 875ft (only ⅓ of original half core). |
| Drilling techniques |
• Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). |
• Drilling: Anaconda - diamond; Rosario - surface (unspecified hammer); Rosario - underground (diamond). • Historic drilling includes diamond core, reverse circulation, hammer bit and rotary air blasting. • For some of the historic drilling, the drill type could not be determined, but was most- likely reverse circulation or open hammer. |
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to |
• Core recovery rate not recorded historically. • Observations by Alderan of Amex Drillholes 520-1 - 520-4 showed very good core recovery - predominantly >90% and up to 100%. • Measures were not taken to maximise sample recovery historically. |
