HENTY SEES NEAR MINE HIGH GRADE GOLD INTERSECTIONS IN NEW AREAS
-
Henty’s standout gold intersections for the quarter include:
-
10.1m @ 12.8 g/t Au
-
4.7m @ 19.2g/t Au
-
10.4m @ 14.8g/t Au
-
7.1m @ 13.0g/t Au
-
1.95m @40.8g/t Au
-
Drilling confirms mineralisation in new areas has potential to extend Resource near current underground workings
-
Exploration program to increase Henty’s mine life well under way with four drill rigs operating and another on way
-
Overall, of 117 holes drilled, 42 intercepts reported greater than 20g/t Au metres
Catalyst Metals Limited ( Catalyst or the Company ) (ASX: CYL ) is pleased to announce that it has continued its exploration success at the Henty Gold Mine in Tasmania. Results are reported here for the period between 1 October and 31 December 2021. These results are in addition to the previous quarter’s high-grade results which were reported to the ASX on 8 November, 2021.
Underground diamond drilling continued with three rigs in operation and a fourth due to arrive in February (a further rig conducts surface exploration). Drilling was carried out in the upper part of the mine on Zone 96, Intermediate Zone and Zone 15 as well as on the Darwin Zones at the south end of the mine (Figures 1,2 and 3).
Many of the intersections are beyond the limits of the 2021 Resource model and have the potential to contribute to an increase in Resources and Reserves as well as a higher gold grade in future production profiles.
Drilling on the Intermediate Zone and Collar Zones is showing high grade mineralisation in a new area that can now be drilled from recently completed development drives. This area has the potential to extend southward where old surface drillholes have shown gold zones in the 7g/t to 14 g/t Au range
Mr Bruce Kay, Catalyst’s Technical Director stated “ The three new development drives have enabled underground drill access to an untested area (Collar Zone) south and down plunge of the Intermediate Zone for the first time ever and this is already generating economic intersections. Surface drilling will also target this area in the current quarter ”

Of the 117 holes drilled during the period, the majority contained gold mineralisation and 42 had intervals greater than 20 g/t Au metres.
High gold grades greater than 50 g/t Au metres were recorded in eleven holes. A further 31 intervals reported greater than 20 g/t Au metres. These intersections are shown on Figure 2 and 3 and included in Appendix 1.
With the arrival of the fourth underground drill rig in February, the drilling activity will increase considerably, enabling the testing of large areas along the Henty Fault above the previously mined areas.

Henty North Exploration Program
Surface drilling commenced in August to test potential for mineralised extensions in the Henty Mine corridor north of the mine. A total of 1,323m was drilled by the end of the Quarter in three holes. Two holes (CEH001, CEH002) drilled in the Henty Mine corridor targeted the projected extension of the Henty structural position and the third hole (CEH003) drilled a geochemical anomalous area west of the Henty Fault.
The current drilling has confirmed the presence of strong Henty style alteration 250m north of the Sill Zone in chemically receptive Zig Zag Hill epiclastics which host some of the mineralisation within the northern end of the mine. The drilling also revealed a previously unknown north-west oriented structural inflection in the Henty Fault associated with significant deformation over a 70m zone downhole. This is interpreted to represent an interfering cross-structure or structures. These holes are undergoing detailed structural analysis prior to sampling and assaying.
On the completion of this program, surface drilling will commence within the Henty Mine corridor targeting extrapolated mineralisation above the Henty Mine workings. Up to seven holes for 2,700m are planned testing targets located up-plunge of high-grade linear shoots of gold within the mineralised Henty Lodes.
Catalyst’s CEO, John McKinstry added “ The results from the quarter continue to demonstrate that Henty Mine has plenty more to give. Catalyst has owned Henty for one year, and our exponential knowledge growth is increasing confidence that new mineralised zones identified will become the next new mining frontiers. ”
This announcement has been approved for release by the Board of Directors of Catalyst Metals Limited.

| Diamond Drill Sampling Techniques and Data Criteria |
Explanation |
| Sampling techniques | The sampling database for this Henty exploration program includes only data collected by diamond drilling (DD). The previous sampling database has been compiled from information collected when the project was under ownership of numerous companies including (listed from most recent): Diversified Minerals (2016 to 2020) Unity Mining (2009 to 2016) Barrick Gold (2006 to 2009) Placer Dome (2003 to 2006) Aurion Gold (2001 to 2003) RGC/Goldfields (1996 to 2001). Details relating to drilling techniques, quality assurance (QA) protocols and quality control (QC) results for data gathered prior to 2009 is largely unavailable. Drilling carried out during this period is collectively termed “Historical Drilling” herein. For drilling carried out since acquisition of the project by Unity Mining in 2009 a reasonable, although partially incomplete, level of information is typically available describing data collection procedures and relevant QAQC. Drilling carried out during this period is collectively termed “Modern Drilling” herein. For drillhole data, either whole core or half core is generally submitted. In areas where infill drilling is required, whole core is typically submitted given that there are other holes available with half core for future reference. Samples are taken at 0.2–1 m intervals and honour different rock types, alteration zones and mineralised zones as defined by geologists. Diamond drilling methods were used to obtain 0.2 m to 1 m length samples which were subsequently pulverised to produce a 30 g charge for fire assay with determination by atomic absorption spectrometry (FA/AAS) for gold. |
| Drilling techniques | Underground mobile diamond drill rigs are utilised to produce either LTK60 or NQ2 size core. Drill core is not routinely oriented. |
| Drill sample recovery | Drilling recoveries are recorded for diamond core samples as part of geotechnical logging. Recovery of drill core is maximised by using drilling techniques and drilling fluids suited to the particular ground conditions. No relationship between grade and recovery has been identified. |
| Logging | For drillhole data, logging is completed on a lap top computer directly into an Excel based spreadsheet which has been designed for the mine site. Logging is carried out at a core shed with adequate facilities including roller-racks, lighting, core photograph facilities and an automatic core saw. A template with project-specific codes has been set up to ensure consistent collection of relevant geological information. Alteration, geotechnical, structure and rock type information are collected into separate tables using standalone codes. Zones of core loss are also recorded. Logging is generally qualitative in nature. All core is stored at site and has been photographed wet. All diamond core has been geologically logged in full (100%). |

| Diamond Drill Sampling Techniques and Data Criteria |
Explanation | |
| Sub-sampling techniques and sample preparation |
Diamond drill core samples are generally half-core, with core sawn in half using a core-saw. In areas where infill drilling is required, whole core may be submitted given that there are other holes available with half core for future reference. An automatic core saw is used to cut the core. Several laboratories and assay techniques have been used throughout the Project’s history. Typically, samples are initially crushed in a jaw crusher to a size of 10 mm. The jaw crusher is cleaned by compressed air between samples. The sample is then riffle split down to 1 kg, with the remaining samples returned as coarse reject to site and stored under cover for future reference. The 1 kg sample is pulverised using an LM5 pulveriser to a size of 85% passing 75 microns, and the mill cleaned with a barren silica flush between samples. 200 g of this fine material is taken via scoop, from which 30 g is taken for fire assay (FA50). Subsampling is performed during the sample preparation stage according to the assay laboratories’ internal protocols. Field duplicates of diamond core, i.e. other than half of cut core, have not been routinely assayed. Sample sizes are considered appropriate for the material being sampled |
|
| Quality of assay data and laboratory tests |
The techniques are considered total. All samples are currently submitted to ALS Burnie for gold analysis. Samples are crushed and pulverised prior to selection of a 30 g subsample for fire assay with determination by atomic absorption spectrometry (AAS). Previous owners have adopted similar methods. Occasionally, Bi, Ag, Cu, Pb, Zn, As and Mo analyses are completed to assist with understanding the nature of the mineralisation and for metallurgical assessment. Cu, for example, may consume cyanide during processing. If required, pulps are sent from Burnie to ALS Townsville for determination via ICP analysis. Details relating QA protocols and QC results for data gathered prior to 2009 is largely unavailable. Monthly QC reports were compiled by Unity Mining for the period 2010 to 2015. The available QC data compiled by Unity Mining has been reviewed by CSA Global and considers the results as suitable to support the data gathered during this time period. QA protocols that have been adopted since 2016 are summarised below. Drilling DVM specifies inclusion of field blanks at a rate of one blank every 30 samples submitted. The blanks are composed of barren basalt material, which is obtained from a commercial distributor in the town of Devonport on the north coast of Tasmania. DVM specifies inclusion of certified reference materials (CRMs) at a rate of two CRM’s every 30 samples of core samples submitted. Commercially available CRM’s covering ranges considered as representing low, moderate and high values for gold were obtained from OREAS. Inclusion of field duplicates for core samples is not routinely carried out by DVM. Pulp duplicates insertion rates are not specified by DVM. Assay laboratory internal QA protocols are relied upon for analysis of pulp duplicates. |

Explanation | |
| Verification of sampling and assaying |
Significant intersections have been verified by alternative DVM company personnel. No twinning has been completed. The summary below relates to current methods. Historical methods are not known with any certainty. Drilling Logging is completed on a lap top computer directly into an Excel based spreadsheet which has been designed for the mine site. Logging is carried out at a core shed with adequate facilities including roller-racks, lighting, core photograph facilities and an automatic core saw. A template with project-specific codes has been set up to ensure consistent collection of relevant geological information. Alteration, geotechnical, structure and rock type information are collected into separate tables using standalone codes. Core is photographed wet at the core shed. Core photographs are stored on the server for future reference. |
|
| The summary below relates to current methods. Historical methods are not known with any certainty; however, the Competent Person considers it is reasonable to assume that industry standard techniques have been adopted over the Projects history. Diamond drillhole collar positions are set out by mine surveyors. The drilling crew has an azi-reader device that enables them to set up at the correct azimuth and dip according to the drillhole plan. Final collar positions are then picked up by Mine Surveyors at hole completion. Downhole surveys are completed using a Devi-flex tool, with surveys taken every few metres. The grid system used is Geocentric Datum of Australia 1994 (GDA94) but the Henty Mine uses a local grid system which is used in the reporting of drill collars and intersections in Appendix 2. The mine surveyors have conversion tables for the conversion of local coordinates and RL to the MGA94. Below are conversions from local grid to MGA94 for two points in the mine. There is no standard transformation conversion because mine grid is oriented at an angle to grid north. Local mine grid Point 1 N 57102.049 E 21513.529 RL =AHD + 2000 Point 2 N 51318.276 E 21509.850 RL =AHD + 2000 MGA94 Point 1 N 5365490.570 E 382559.064 Point 2 N 5360057.736 E 380580.385 |
||
| Data spacing and distribution | Areas that remain in situ are generally drilled at 10–20 m E by 10–20 m RL spacings in the Mineral Resource area. The drill spacing varies between deposits, and lenses within a deposit. Areas towards the periphery of the lenses are often drilled at broader spacings. Compositing was not applied at the sampling stage. |
|
| Orientation of data in relation to geological structure |
The drilling has been undertaken at various orientations, given the limited platforms available underground. For the most part, holes are drilled at a high angle to the mineralisation. Some holes, however, have been drilled close to sub-parallel to the mineralisation. The relationship between the drilling orientation and the orientation of key mineralised structures is not considered to have introduced a sampling bias. |
|
| Sample security | The summary below relates to current methods. Historical methods are not known with any certainty; however, the Competent Person considers it is reasonable to assume that industry standard techniques have been adopted over the Projects history. Core is transported to the core shed for processing, which is locked at the end of each day. Core samples are placed in a polyweave sack for transportation to the laboratory. The primary laboratory (ALS in Burnie) collects the samples each morning. |

| Diamond Drill Sampling Techniques and Data Criteria |
Explanation | |
| Audits or reviews | No processes or data used in developing the release of exploration results have been subject to audit or review by non-company personnel or contractors so as to reduce costs and timelines for reporting. Catalyst Metals Limited has relied on information from Competent Persons at CSA Global and Henty Mine CSA Global completed a review of data collection techniques in 2017 |
| Reporting of Exploration Results Criteria |
Explanation |
|---|---|
| Mineral tenement and land tenure status |
Henty Gold Mine Tenements in Tasmania are owned by Unity Mining Pty Ltd Land tenure consists of three Mine Leases, 7M/1991, 5M/2002 and 7M/2006. Two Exploration Licences adjoin the Mine Leases; EL 8/2009 to the north and east and EL 28/2001 to the south. The tenements are in good standing and no known impediments exist. |
| Exploration done by other parties | Other companies to have held the project leases include: Unity Mining (2009 to 2016) Barrick Gold (2006 to 2009) Placer Dome (2003 to 2006) Aurion Gold (2001 to 2003) RGC/Goldfields (1996 to 2001) |
| Geology | The Henty deposit lies within the Mt Read Volcanic (MRV) Belt in western Tasmania. The belt hosts several world-class polymetallic ore bodies including the Hellyer, Que River, Rosebery, Hercules and Mount Lyell deposits. The whole belt has been overprinted with a regional lower green schist facies metamorphism. Mineralisation consists of a series of small high-grade lenses of gold mineralisation hosted in quartz-sericite altered volcaniclastic and volcanic rocks that occupy a large sub-vertical quartz-sericite alteration shear zone. Gold is present as both free gold and as gold-rich electrum associated with chalcopyrite and galena in the main mineralised zone. |
| Drill hole Information | All exploration results reported here are from diamond drilling (DD) subsequent to 1 July 2020 which was the cut-off date for the CSA resource estimation summarised in Appendix 1. The historic sampling database has been compiled from information collected when the project was under ownership of numerous companies including (listed from most recent): Diversified Minerals (2016 to 2020) Unity Mining (2009 to 2016) Barrick Gold (2006 to 2009) Placer Dome (2003 to 2006) Aurion Gold (2001 to 2003) RGC/Goldfields (1996 to 2001). Details relating to drilling techniques, quality assurance (QA) protocols and quality control (QC) results for data gathered prior to 2009 is largely unavailable. Drilling carried out during this period is collectively termed “Historical Drilling” herein. For drilling carried out since acquisition of the project by Unity Mining in 2009 a reasonable, although partially incomplete, level of information is typically available describing data collection procedures and relevant QAQC. Drilling carried out during this period is collectively termed“Modern Drilling”herein. |

| Reporting of Exploration Results Criteria |
Explanation | |
| Data aggregation methods | DDH assay samples are collected at 1m intervals in the first instance, but smaller intervals are sampled where related to specific mineralised units. No top-cutting applied to assay data. Significant intersections in first-pass exploration are usually reported as those with assays in excess of 0.5g/t Au (with internal dilution of two consecutive assays or less Reported zones are continuous, with no sample or assay gaps. Holes without zones of significance are tabulated detailing the greatest assay value achieved. |
|
| Relationship between mineralisation widths and intercept lengths |
The dip of mineralisation is expected to be steep west dipping, but drill hole azimuths are variable due to lack of availability of underground drill platforms. The dip of mineralisation is not always consistent or known and the true width of mineralisation has not been resolved. As such, significant mineralised intersections have been reported as downhole intervals. |
|
| Diagrams | Figure 1 shows the longitudinal projection of the Henty resource and mining area with an inset enlargement for the October- December 2021 drilling Figures 2 and 3 show the enlargement diagram with diamond drill holes in longitudinal projection |
|
| Balanced reporting | All drilling inclusive of holes which did not contain significant intersections are included in Tables 1a and 1b |
|
| Other substantive exploration data | Other exploration results that have been used in the CSA resource estimation have not been included in this report. |
|
| Further work | Further drilling at Henty will continue to be focussed on the mine corridor adjacent or parallel to the known resource and will also test specific structural targets beyond the mine environs. |
