Freehill Mining Limited (ASX: FHS ‘Freehill’ or ‘the Company’) is pleased to announce that assay results have now been received from a detailed channel sampling and structural mapping program completed in late August 2020 across the El Dorado project area. Assays continue to show strong copper and gold mineralisation.
Whilst advancing development of the company’s JORC compliant 67 million tonne magnetite resource at the 100% owned Yerbas Buenas project is the Company’s priority, Freehill is pleased to confirm that follow-up exploration work at the El Dorado concessions continues to validate three high grade copper and gold zones and several potential iron structures. Significant assay results from the recent channel sampling survey include:
| Copper assay | Gold Assay | Iron Assay |
|---|---|---|
| 2.51% | 1.32 ppm | 18.75% |
| 2.25% | 0.51 ppm | 7.90% |
| 0.11% | 1.81 ppm | 11.05% |
| 0.08% | 6.86 ppm | 6.82% |
| 0.57% | 0.03 ppm | 12.40% |
| Table 1 – Channel sampling highlights |
The El Dorado project covers 750 hectares over eight tenements and adjoins the northern boundary of Freehill’s Yerbas Buenas project area (Fig 1). El Dorado was acquired by Freehill in March this year and takes Freehill’s exploration and development area to approximately 1,250 Hectares in Chile’s highly prospective iron-copper-gold (‘IOCG’) belt. The project is located 7km WSW of the historic copper mining centre of La Higuera.
Encouraging Copper & Gold Mineralisation
Additional detailed surface sampling has been carried out in the central portion of El Dorado to test structural features that may influence mineralisation and to better define localised structures. Channel sampling has identified several additional zones of copper mineralisation with the most prospective area coincident with a magnetic high shown as D1 in Figure 2.
The channel sampling follows on from a rockchip campaign completed in July that identified three zones of mineralisation. (See ASX release: 25 Aug 2020).
Geochemical sampling confirms a NW-SE structural trend of mineralization and is consistent with a high chargeability

zone identified in an earlier IP survey on Yerbas Buenas (Figure 8). Induced Polarisation surveys were carried out in the northern portion of the Yerbas Buenas concessions in early 2019 (Reported ASX release: 25 February 2019 & 17 April 2019).
Additional images of channel sampling points and the type of mineralisation in the area are shown in Fig 6 and 7.
A single 400m exploratory diamond drill hole (ES001) was completed in the northern extremity of the Yerbas Buenas concession within the northern IP anomaly and the core was recently relogged leading to a reinterpretation of the geological model.
The hole yielded several intersections with intense alteration and very encouraging copper sulphide mineralisation within the first 200m from collar. Over 18 intervals had copper grades greater than 1000ppm with several intervals exceeding 2,000ppm (0.2% Cu) including one interval of 3240ppm (0.324%) at only 114m depth. Diamond core images are shown in Fig 4 & 5 indicating visible copper sulphide mineralisation with significant assays for the drill hole presented in table 2. A complete list of Cu, Au & Fe assays for DDH ES-001 are provided in Attachment 1.
Results from the recent channel sampling study shows El Dorado to have significant mineral alteration which is associated with Cu-Fe sulphide mineralisation which can contain gold. The work also identified a number of NW-SE trending structures that where channel sampled having significant gold, copper and iron grades of up to 22g/t Au and 9% Cu were associated with the trend ( see Fig 3 & Table 1).
El Dorado Ground Magnetic Geophysics Survey
A ground magnetic survey (Fig 2) was completed recently in the El Dorado concession area with continuous profiles along E-W lines and line spacing of 50 m for a total survey length of 157 line km. Several magnetic highs are evident and will be tested during future drilling campaigns.
The recent ground magnetics data from El Dorado has been merged with data acquired during previous ground magnetics surveys at Yerbas Buenas and are shown as a single amalgamated ground magnetics image in Fig 3 demonstrating the approximate N-S continuity within both project areas.
The geophysics indicate a large NW structure, previously identified on the lower portion of the Yerbas Buenas project area, extending into the El Dorado tenements. Copper, gold and iron channel sampling locations are shown in Fig 8-11 with Figure 8 showing the Induced Polarisation chargebility signature at -300m.
This primary structure appears to control copper mineralization in both the northern end of Yerbas Buenas and El Dorado. Induced Polarisation (IP) lines are planned to test the southern part of El Dorado for copper mineralization and will focus on the area shown as D1 which is coincident with significant surface mineralisation, which is adjacent to the IP survey in the northern part of Yerbas Buenas.
The strongest magnetic anomaly within El Dorado is labelled D1 and modelling suggests that the magnetite mineralization may extend to a significant depth at D1 and the magnetite grade may increase, slightly, with depth.
The National Geology and Mining Service ( Sernageomin) 1:100,000 geological mapping shows a clear NW contact point between sub-volcanic complexes and dioritic intrusives in the area where higher grade copper and gold mineralisation has been mapped by Freehill.

Comment
Chief Executive Officer Peter Hinner said: “These channel sample results reaffirm our view that El Dorado has extensive copper mineralisation which exposes us to another major commodity with excellent long-term supply and demand characteristics. The IP Survey that is currently underway will help us better determine the extent of future copper exploration undertakings. That said, the rock chip sample from August and now these channel sampling results are clearly showing us that El Dorado is well endowed with extensive copper mineralisation.
“Also highly encouraging are the assay results we are reporting for the first time from a single hole we drilled at Yerbas Buenas, which confirm superb copper mineralisation. To have more than 18 intervals with copper mineralisation of meaningful grade is outstanding. While we are very much focused on advancing the feasibility study for the magnetite at YB, these results we have reported today on the copper give us sufficient confidence to now develop a comprehensive exploration and development program for our copper across Yerbas Buenas and now El Dorado. The IP program that has just started is the next major step in this exploration.”

JORC Code, 2012 Edition – Table 1 report
Freehill Mining Limited
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. |
• Data provided includes Channel sampling, diamond drilling of ES-001 hole and ground magnetic geophysics. • NQ diamond core drilling carried out by DV Drilling using a Cortech 1300G maxi track mounted drill rig. • Refer to Attachment 2 of announcement. Hole ES-001 orientated as shown, and were drilled at dip of 50.2° in a north direction. • Core remained in the custody of the company after being picked up from the drilling site. • Protocol set up and several magnetic • The drill hole locations were located by survey differential GPS and checked against known government benchmarks. • Down hole surveys were conducted on all holes during drilling for azimuth and orientation using Reflex Ezi-Gyro and Reflex-Ori • Surface sampling undertaken using conventional methods described in previous table 1 versions. Assays from current sampling campaign and previous rockchip campaigns provided in Attachment 1 of media release. • Ground magnetics carried out Agarli geofisica using 50m line spacing and the same equipment used in previously reported surveys/ |
| 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). |
• DDH drilling was the method chosen for hole drilled. The core diameter was HQ triple tube (in weathered rock and surficial sands ) and NQ size in competent rock. |
| 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 preferential loss/gain of fine/coarse material. |
• Core recoveries were observed during the drilling and any core loss was noted in the geological logs. • Samples were checked by for volume, moisture content, possible contamination and recoveries. Any issues are discussed with the drilling contractor. • Some core loss was apparent and noted (generally <5%) in the weathered portion of the holes, howeverthiswas generallyminor. |
| 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. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. |
• All core sample logged by a qualified geologist with experience in magnetite deposits in Chile to a level appropriate with the style of mineralization • Logging was both qualitative and quantitative • Lithology, alteration, mineralization level & magnetic susceptibility all logged • All core remained as full core until fully logged and magnetic susceptibilitymeasurements |

| recorded. • Four magnetic susceptibility readings taken of each metre of core prior to cutting and the averaged recorded. • All holes were logged in full. • Channel sampling samples and site mineralistion all logged by Tracking SpA senior geologist in presence of Freehill geologist. |
||
| Sub-sampling techniques and sample preparation |
• 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 instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
• All ES001 core cut using a standard electric diamond saw. • The preparation of samples follows industry practice. • Following detailed logging and magnetic susceptibility measurements taken the core was marked for orientation and cut in half by diamond saw. • Assay sample intervals were then marked by the geologist and ½ core samples bagged into plastic bags and dispatched to AGS Coquimbo, Chile for ore preparation. • Ore preparation was a standard ore prep method which involved oven drying, crushing to ~5kg to 85% -10# and a 250g sub-sampled pulverized of 95% passing 150# • Field QA_QC involved submitting blank material and also certified standard pulps. The laboratory also carried out internal standard QA_QC procedures. The sample sizes are considered appropriate to the grain size ofthematerialbeing sampled. |
| 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. • 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. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
• Sample preparation of channel samples completed by ALS Coquimbo and pulps sent to ALS Lima. • Sample preparation and assaying of DDH ES001 samples done by Activation Geological Services Coquimbo laboratory. Pulversied to 95% passing 150#. Gold assayed by 30g Fire Assay with AAS finish. Copper and other elemenst assayed by 4 acid digest followed by ICP. |
| Verification of sampling and assaying |
• The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. |
• No twinned holes have been completed to date – ES001 was a reconnaissance hole. • Drill logs and geological logging has been done on hand written sheets which are converted to digital format each day. |
| 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. • Specification of the grid system used. • Quality and adequacy of topographic control. |
• Hole location has been done using differential GPS by a registered surveying company. • Drill collar elevations and project area topography have been double checked by GeoAmbiente using a GPS GEODÉSICO V60 GNSS MARCA HI-TARGET drone with +/- 1.5mm accuracy • All digital data, maps and data products associated with the drilling program areprovided in coordinate |

• 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: o easting and northing of the drill hole collaro elevation or RL (Reduced Level – elevation abovesea level in metres) of the drill hole collar o dip and azimuth of the holeo down hole length and interception deptho 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. _ |
• Table of drill hole positions provided in report appendix |
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually 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. • The assumptions used for any reporting of metal _equivalent values should be clearly stated. _ |
• Not applicable for currently reported magnetic susceptibility measurements. |
| 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(eg ‘down hole length, true width not known’). _ |
• Not applicable for currently reported magnetic susceptibility measurements. • Geometry of mineralization not yet determined but will be determined as a result of the current drilling campaign |

| 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. _ |
• This document is considered to be a balanced report of the diamond core logging and magnetic susceptibility measurements taken to date. |
| 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. _ |
• Not applicable for magnetic susceptibility measurements. |
| Further work | • The nature and scale of planned further work (eg 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. |
• Detailed mapping and rock-chip sampling of main geophysical targets are being undertaken together with sampling in a 0.5 Hec bulk sampling pit • Surface sampling, mapping and trenching/pitting of the IP anomaly is planned for Q4 2019 where it appears to be exposed at surface. • Followup RC ‘in-fill’ drilling of the YB6 magnetic structure is planned for Q2 2020 to upgrade the resource category |
