Cygnus Gold | Gold Road JV Update
ASX ANNOUNCEMENT:
15 October 2019
ASX: CY5
CORPORATE DIRECTORY
Non-Executive Chairman Michael Bohm
Managing Director James Merrillees
Non-Executive Directors
Simon Jackson Oliver Kreuzer
Company Secretary
Michael Naylor
Cygnus Gold ( Cygnus or the Company ) ( ASX:CY5 ) is pleased to provide an update on activities on the Company’s joint ventures with Gold Road Projects, a wholly owned subsidiary of well-credentialed ASX-listed gold producer Gold Road Resources Ltd ( Gold Road ) ( ASX:GOR ).
The Cygnus - Gold Road joint ventures (JV) cover an area of more than 5,000km[2] in the Wheatbelt region of Western Australia (Figure 1). These tenements are located along the Yandina Shear, a largely unexplored regional structure interpreted to control the location of gold deposits such as Tampia, Griffin’s Find and Lake Magenta.
Recent aircore drilling at the Hammerhead prospect returned additional widespread, anomalous gold including 3m @ 0.35g/t Au from 52m (hole LGAC0058) and 6m @ 0.28g/t Au from 56m to end of hole (hole LGAC0091). These intersections are associated with widespread anomalous gold pathfinder elements such as arsenic, copper, and molybdenum, and are in addition to the results reported in CY5 ASX announcement 10 July 2019.
Anomalous gold and pathfinder anomalism have now been returned from four of the eight broad spaced drill lines through transported cover over nearly 15km strike length of interpreted greenstone rocks at Hammerhead.
In addition to ongoing targeting at Hammerhead, exploration activity has included regional targeting on the Wadderin and Yandina JVs, which has identified a number of high priority targets for drill testing.
The Company is now planning a program to extend and infill the AC drill coverage at Hammerhead as well as deeper reverse circulation (RC) drilling under the best results to date. The AC program will include first pass traverses across the higher priority Wadderin and Yandina targets. These programs are planned to commence immediately post-harvest in late Q4.
Cygnus Gold’s Managing Director James Merrillees said, “Even though early stage, the Hammerhead prospect is now a focus area on the Lake Grace JV where drilling programs are planned to commence over the coming months. Other targets on the Wadderin and Yandina JVs fill a pipeline of joint venture funded projects to be tested over the coming 6-12 months.
–
I’d like to thank our partners Gold Road and acknowledge their support as we aim to emulate their success at Yamarna in the Southwest, an equally underexplored area within the prolific Yilgarn Craton.”

LAKE GRACE JV
The current focus on the ~800km[2] Lake Grace JV is the Hammerhead prospect, a target identified from regional aircore drilling of a zone of surface gold (Au) anomalism coincident with the prospective Yandina Shear Zone.
The original 100m-spaced ‘discovery’ AC traverse at Hammerhead was a regional traverse over unexplored, soil-covered terrain more than 16km from the nearest historical drill holes. This line of drilling intersected widespread >20ppb Au and included (refer CY5 ASX announcement 10/7/2019)[1] :
-
Hole LGAC0019 with 1m @ 0.15 g/tb Au from 51m, with strong arsenic (As), copper (Cu), lead (Pb) and zinc (Zn) in mafic rocks; and
-
LGAC0022, 300m east of LGAC0019, with shallow BIF reporting intersections with gold to 116ppb Au and As to 200ppm.
Follow up aircore drilling (71 holes for 3,315m) at Hammerhead has identified further anomalous gold and pathfinder mineralisation in step out drilling from the original discovery line, nominally on 1,500m spaced lines with holes at 100m centres along lines. Eight lines of drilling were completed over 9.8km of strike length of greenstones at Hammerhead on nominal 1,500m spaced lines with 100m hole spacing (Figure 2).
Significant results include:
-
LGAC0058 with 3m @ 0.35g/t Au and 512ppm As from 52m, in a broader halo of weakly anomalous Au (23m @ 67ppb Au), copper (Cu), zinc (Zn) and As in greenstone basement (Figure 3)
-
LGAC0091 with 6m @ 0.28g/t Au from 56m to end of hole (EOH) interpreted as basement, with strong pathfinder elements (Ag, Cu, Mo) in transported cover above this intersection (Figure 4)
-
LGAC0101 with 4m @ 0.17g/t Au from 42m and 2m @ 0.11 g/t Au from 49m (just above EOH) within a wider zone of anomalous Au (14m @ 0.097g/t Au) hosted in mafic volcanics. This hole was the last hole at the end of this traverse, on the edge of a large surface geochemical anomaly open to the north east (Figure 5).
Importantly, drilling intersected several zones with more than 1,000ppm arsenic (As) associated with the gold anomalies. Arsenic is considered an important pathfinder element for gold mineralisation in this part of the Yilgarn Craton, as exemplified by the nearby Tampia and Griffins Find deposits.
These results are considered significant given the wide line spacing, broad hole spacing, and depth of transported cover, and confirm the gold potential for this part of the Yandina Shear. Further drilling is now planned to vector towards targeted higher grade and thicker zones within this 15km strike length of prospective geology with a program of:
-
Infill and expanded drilling on lines of AC drilling targeting the interpreted shear and mafic rock unit along strike from the existing holes
-
Drilling of deeper RC holes under the best AC anomalies intersected in holes LGAC0058,091 and 101.
WADDERIN & YANDINA JVs
The Wadderin and Yandina JVs are also targeting gold mineralisation associated with the regional Yandina Shear. Due to the sparse outcrop in these large tenement packages exploration has been driven by detailed geological interpretation of geophysical datasets to map out the geology and structures thought to control gold mineralisation.
As well as extensions of the Hammerhead prospect on to the Yandina JV, targeting work has identified in excess of 50 target areas which have now been ranked with geological reconnaissance and surface sampling already underway or complete on most of the highest priority targets.
Land access agreements have now been negotiated with farmers covering the priority targets at Yandina and Wadderin and first pass aircore drilling of these targets is currently scheduled to commence in early 2020.

JOINT VENTURES UPDATE
As previously announced Gold Road has now reached the expenditure required to earn 51% of the Lake Grace Earn-in project, and has elected to form a joint venture to earn an additional 24% interest (75% in total) in the project by spending a further $500,000 within 18 months (refer CY5 ASX Announcement 1 July 2019)1.
On the Wadderin Earn-in project, Cygnus and Gold Road have agreed to extend the minimum expenditure time required to achieve the $900,000 until December 31 2019 and extend the earn in period to 31 December 2020 where Gold Road is required to spend $1,600,000 on exploration expenditure to earn 51% (refer GOR ASX announcement 10/10/2017). All other terms remain unchanged.
The Hyden group of tenements were granted during September and these will be added to the existing Yandina JV.

APPENDIX 2: JORC Code, 2012 Edition – Table 1
Section 1 Sampling Techniques and Data – Lake Grace JV Aircore Drilling
(Criteria in this section apply to all succeeding sections.)
| 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. The results in this release relate to holes LGAC0028-LGAC0101 all drilled within the Lake Grace JV (Cygnus Gold 49%, diluting to 25%). |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Sampling was undertaken under Cygnus Gold’s standard procedures including QAQC. The laboratory also applied QAQC protocols. One metre samples were collected from individual plastic bags using a spear sampler, although scoops were used where the spear method was unsuitable (e.g. when the sample was wet). A four-metre composite was then made up these individual one metre samples to obtain an approximately 2.5 - 3kg sample. An individual one metre ‘end of hole’ sample was also collected for submission. |
|
| 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. All samples are pulverised at the lab to 85% passing -75µm to produce a 50g charge for Fire Assay with an ICP-AES finish. |
|
| 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). Aircore drilling with a blade bit was completed to “refusal”, giving 1-2m of fresh bedrock sample. Where possible lengths of 3-12m of hammer drilling was undertaken with a face sampling hammer bit. Drill holes were angled perpendicular to the interpreted stratigraphy. The program was supervised by experienced Cygnus Gold geologists. |
| 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. One metre samples were collected in individual plastic bags via a cyclone on the rig. Sample recovery was estimated visually and was generally around 80-90% but may be as low as 30-40% in some near surface samples. |
10
| Criteria | JORC Code explanation Commentary |
|---|---|
| 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. |
|
| 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. Samples were wet sieved and logged for colour, weathering, grain size, major lithology (where possible) along with any visible alteration, sulphides or other mineralisation The entire hole is logged by experienced geologists employed by Cygnus Gold using Cygnus Gold’s logging scheme. The level of detail is considered sufficient for early stage exploration of the type being undertaken here. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. Geological logging is qualitative whereas magnetic susceptibility are quantitative All chip trays are photographed in the field. |
|
| The total length and percentage of the relevant intersections logged. All holes are logged over their entire length. |
|
| 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. Samples were composited over 4m intervals with a 1m end of hole sample also collected. Samples were generally dry and duplicate samples were taken at the frequency of 1 duplicate per 50 samples. All samples were prepared at the ALS Laboratory in Perth. All samples were dried and pulverised to 85% passing 75µm and a sub sample of approximately 200g retained. A nominal 50g charge was used for the fire assay analysis. The procedure is industry standard for this type of sample and analysis. Sample sizes are considered appropriate given the particle size and the need to keep 4m samples below a targeted 3kg weight which meet the targeted grind size using LMS the mills used in sample preparation by ALS. |
| 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. Samples were analysed at ALS Laboratory, Perth. The analytical method used was a 50g charge for Fire Assay with an ICP-AES finish for gold only. This method gives a near total digest of the sample and is considered appropriate for the material and mineralisation. |

|---|---|
| Representative samples were also analysed using the ALS method ME-MS61 which is a four-acid digest with an ICP-MS or ICP-OES finish depending on the element being reported with Cygnus requesting analyses for 48 elements. Four acid digestion is considered a ‘near total’ digest. |
|
| 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. Magnetic susceptibilities were recorded in the field using a magROCK magnetic susceptibility metre with a sensitivity of 1x10-5SI units. |
|
| 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. Cygnus has submitted a mix of Certified Reference Materials (CRMs) and blanks at a rate of five per 100 samples. Umpire checks are not required for early stage exploration projects. |
|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. Significant results are checked by the Project Geologist and Competent Person in addition to checks by the Database Manager. |
| The use of twinned holes. No twined holes have been completed at this early stage of exploration. |
|
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. All field logging is carried out on a laptop using Ocris Mobile software. Logging data is submitted electronically to the Database Manager based in Perth. Assay files are received from the lab electronically and all data is stored in the Company’s SQL database managed by Expedio Ltd in Perth. |
|
| Discuss any adjustment to assay data. No assay data is adjusted. |
|
| 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. Aircore collars were determined by handheld GPS, which are considered accurate to ±5m in Northing and Easting. |
| Specification of the grid system used. The grid system used is MGA94 Zone 50 (GDA94). |
|
| Quality and adequacy of topographic control. RLs are allocated to the hole collar using a DTM derived from detailed topography. The accuracy is estimated to be better than 2m in elevation. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Aircore lines are spaced between 400 and 2,000m apart with holes spaced ~100m along lines. |
| Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. The current drill spacing is broad and designed to follow up regolith anomalism and structural targets identified from regional geophysical surveys. |
|
| Whether sample compositing has been applied. Samples were composited over 4m intervals except for the ‘end of hole’ sample which is a single, 1m sample of the last metre of drilling. |
|
| Orientation of data in relation |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. Drilling is orthogonal to the general trend of stratigraphy. |

|---|---|
| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The drill holes reported here were all drilled within E70/4853 (Lake Grace tenement) which is subject to an earn-in, joint venture agreement with Gold Road Projects Pty Ltd, a 100% owned subsidiary of Gold Road Resources Ltd. The landownership within E70/4853 is mostly freehold, and Cygnus has Land Access Agreements according to the Mining Act 1978 (WA) with the underlying landowners that own the ground. Cygnus has signed a standard Indigenous Land Use Agreement (ILUA) for E70/4853. |
| The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. The Lake Grace tenement (E70/4853) is in good standing with the Western Australian Department of Mines, Industry Regulation and Safety (DMIRS). Cygnus is unaware of any impediments for exploration on this licence. |
|
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. Historical exploration within E70/4853 has comprised the following: • 1994 to 1995: North Limited explored the Lake Grace area as part of their larger 400km2Southwest Yilgarn Gold Project. The Panhandle Prospect, located within the northern corner of the current E70/4853, was discovered during a program of airborne geophysics and soil sampling (412 samples total). The Panhandle gold anomaly was interpreted as being spatially coincident with subcropping mafic granulite. The anomaly was subsequently tested with a 53 hole aircore program which failed to further delineate the anomaly. • 2003 to 2008: The Lake Grace area was explored during this period by Dominion as part of their larger Newdegate gold super-project, which spanned ~2,000km2. Most of the exploration work carried out by Dominion during this time too place outside the boundary of the current EL70/4853, with the exception of 86 roadside samples which returned a peak gold value of 8.5ppb Au. • 2013 to 2014: The Lake Grace project area was explored by Auzex Exploration Ltd as part of a joint venture with Panoramic Resources Ltd. During this time, exploration work on the current EL70/4853 comprised desktop-based gold prospectivity modelling and geophysical interpretation. Refer to the Independent Technical Assessment Report within Cygnus’ Prospectus dated 22 November 2017 for details of and references to the previous work. |
| Geology | Deposit type, geological setting and style of mineralisation. Cygnus’s projects are located in the Southwest Terrane of the Archaean Yilgarn Craton. Project-scale geology consists of granite-greenstone lithologies that were metamorphosed to amphibolite to granulite facies grade. The Archaean lithologies are cut by Proterozoic dolerite dykes. Mineralisation observed to date is similar in style to that at the nearby Katanning, Tampia and Griffins Find gold deposits. These deposits, classified as metamorphosed orogenic lode deposits, are characterized by multiple stackedlodes up to25mthickand greaterthan 1,000m longinquartz richgneiss andfelsic to |

| intermediate granulite. Narrow high-grade ore shoots (>10 g/t Au) are commonly enclosed within broader low-grade envelopes (<2 g/t Au) hosting the bulk of the ore at these deposits. Gold is commonly associated with pyrrhotite, pyrite, chalcopyrite, magnetite ± molybdenite. Quartz veins are rare. The mineralization is controlled by the schistosity of the metamorphosed host rocks and plunging folds preserved in these rocks. Please refer to the Independent Technical Assessment Report within Cygnus’ Prospectus dated 22 November 2017 for more detail. |

| 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: 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. All assay and collar information are tabulated in Appendix 1 of this report. All significant intercepts are reported at a 0.1 g/t Au cut-off. Summaries of previous significant drill intersections at Lake Grace (including JORC Table 1 information) are provided in the Independent Technical Assessment Report within Cygnus’ Prospectus dated 22 November 2017. |
| 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. Intersection lengths and grades for all holes are reported as a down-hole, length weighted average of grades above a cut-off of 0.1 g/t Au. Lower grade intervals are quoted to provide context for significant intervals. |
| 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. Intersection lengths and grades for all holes are reported as a down-hole, length weighted average of grades above a cut-off of 0.1 g/t Au and may include up to 1m of ‘internal waste’ below that cut-off. Details of all intersections are included in Appendix 1 in the body of the announcement. |
