Silver Mines Limited COVID-19 Response

During the March 2021 quarter, Silver Mines Limited (ASX:SVL) (“Silver Mines” or “the Company”) continued to carry out measures in response to the impact of the COVID-19 pandemic. The Company’s priorities are to protect the health and safety of our staff, contractors and local communities, while maintaining the integrity of our business.

The Company adheres to the directives from Federal and State Government and has put in place comprehensive COVID-19 Policies and Procedures. This has allowed our current operations to continue safely and with minimal interruption.

Bowdens Silver Project

The Bowdens Silver Project is the largest undeveloped silver deposit in Australia and lies within Exploration Licence 5920, which is 100% held by the Company. The Project is located in central New South Wales, approximately 26 kilometres east of Mudgee.

In May 2020, the Company completed and submitted the Bowdens Silver Development Application and associated Environmental Impact Statement (EIS) to the New South Wales Department of Planning, Industry and Environment. The proposed development comprises an open-cut mine feeding a new processing plant with a conventional milling circuit and differential flotation to produce two concentrates that will be sold for smelting off site.

Plant capacity is designed for 2.0 million tonnes per annum with a mine life of 16.5 years. Life of mine production is planned to be approximately 66 million ounces of silver, 130,000 tonnes of zinc and 95,000 tonnes of lead.

Summary points of the EIS include:

• Considerable local economic benefits with substantial local job creation;

• Minimal impacts on surface water and groundwater during and after operations;

• An arrangement to source surplus water from nearby coalfields via a dedicated water pipeline thereby limiting the requirement to source water locally;

• No physical human health risk issues of concern have been identified;

• A progressive rehabilitation plan has been committed to with rehabilitation occurring throughout the life of the mine;

• No significant impacts upon migratory or threatened species. The Project’s biodiversity offset program will see a significant area of land conserved in perpetuity;

• Relocation of a local road around the mine site with the result that the majority of traffic would avoid the local township of Lue;

• Aboriginal Cultural Heritage assessment has been concluded in conjunction with the local Aboriginal communities, with agreement on ongoing management; and

Silver Mines Limited ABN: 45 107 452 942

==> picture [122 x 34] intentionally omitted <==

• More broadly, the potential for amenity-related impacts would be managed over the life of the mine through a range of management commitments, monitoring and reporting.

The EIS was placed on an eight-week public exhibition which concluded during the September 2020 quarter. Results from the public exhibition may be viewed at the New South Wales Department of Planning, Industry and Environment Major Projects website (https://www.planningportal.nsw.gov.au/major-projects).

From the exhibition process, the Company received no objections to the Project from any of the Government agencies and received resounding public support. The Company will be shortly responding to received submissions.

During the March 2021 quarter, the Company announced the submission its Mining Lease Application (“MLA 601”) to Government for the development of the Bowdens Silver Project.

Silver Mines continues an extensive program of consultation with relevant Government departments, local communities, and other interested stakeholders. The program examines the potential impacts and benefits of exploration and development across the substantial Bowdens Silver tenement portfolio. Consultation processes focus on the current potential mine development area and the wider area where the Company is commencing or undertaking exploration programs.

Bowdens Project Exploration

Introduction

During the March 2021 quarter, the Company provided updates on exploration activities at the Bowdens Silver Project (Refer to releases of 28[th] January 2021 and 19[th] February 2021).

Diamond drilling continues to test extensions of potential source/feeder structures to the Northwest High-Grade Zone and Main Zone at depth below the proposed open pit design. The Northwest Zone has previously returned spectacular high-grade silver results while drilling into the modelled mineral resource in the Northwest of Main Zone show substantially stronger mineralisation than what was indicated by previous drilling. The Northwest zone extends from approximately 30 metres below the base of the proposed Bowdens Silver open pit and is a mineralised zone being targeted for potential high-grade silver underground mining scenarios (refer to Figures 1 and 2).

Figure 2. Schematic cross-section through the north of Bowdens in proximity to proposed open pit.

Drilling in the Northwest High-Grade Zone has shown the mineralisation consists of breccia and veined sulphides dominated by silver sulphides, galena (lead sulphide) and sphalerite (zinc sulphide) within the welded tuff of the Rylstone Volcanics.

Mineralisation intersected in BD20017 from 248 to 256 metres show breccia and vein textures indicative of boiling and episodic hydrothermal events. These intercepts are approximately 30 metres down-plunge and to the south of the high-grade intercept of 2.4 metres @ 701 g/t silver equivalent from BD20012 (Refer to release dated 8[th] October 2020) and the interpreted fluid conduit.

Hole BD20016 tested a western and southern extension of BRC12037 (4 metres @ 1007 g/t silver equivalent) and intersected several narrow high-grade zones (refer to Table 1). BD20014 was drilled to extend the Northwest Zone to the north of current known limits with significant results also shown in Table 1.

Assay results have been returned BD21002 from the Main Zone and the Aegean Zone below the proposed pit. The latest results, from the upper portion of the hole (89.0 metres to 130.6 metres depth), fall within the modelled mineral resource yet show substantially stronger mineralisation than what was indicated by previous drilling.

The Aegean Zone is defined by numerous high-grade silver intercepts from previous drilling as a 2 to 8 metre thick, 150 metre in strike and 30 metre wide zone of predominantly silver mineralisation with the base of the welded tuff. Historic intercepts include 2 metres at 755 g/t AgE in BGR304, 3 metres at 725 g/t AgE in BGD040, 2 metres at 1421 g/t AgE in BD16005 and 14 metres at 277 g/t AgE in BD16002. The Zone is being tested for extensions to the northwest and towards the Northwest High-Grade Zone for underground mining scenarios.

Results from BD21002 have extended the Aegean Zone some 50 metres north with an intercept of 8 metres at 202 g/t AgE and 2 metres at 250 g/t AgE. A further hole, BD21003 is also targeting extensions to this zone with sampling completed on this hole. Detailed modelling work and interpretation of these results is underway.

Drilling is on-going with a priority to target and define the location and orientation of the feeder structures to the Bowdens Silver Deposit. This includes testing the Northwest Zone and the potential for high-grade zones linking the Northwest Zone to the Main Zone. With the latest results, the Northwest High-Grade Zone is now defined as 1 metre to 20 metres thick, 200 metres width (east to west) and continues down plunge/dip to the northwest for at least 300 metres. This zone is not yet closed off and drilling presents further potential for expansion.

BD21001 was drilled to test the area between the Main Zone and Northwest High-Grade Zone with a very high-grade vein intercepted between 279 and 280 metres depth returning 1 metre @ 1529 g/t silver equivalent. This hole was also designed to test a continuation to the north of the modelled dacite intrusion which did not intersect any intrusion. This, combined with detail gravity modelling, suggests that the dacite could have a steep southern continuation.

1.Bowdens’ reported silver equivalent is consistent with previous reports and current resource modelling based on assumptions: Ag Eq (g/t) = Ag (g/t) + 33.48Pb (%) + 49.61Zn (%) calculated from prices of US$20/oz silver, US$1.50/lb zinc, US$1.00/lb lead, and metallurgical recoveries of 85% silver + gold, 82% zinc and 83% lead estimated from test work commissioned by Silver Mines Limited. 2. Silver equivalent updated to also include significant gold credit assuming the same recovery as silver, with gold:silver price ratio of 80:1 based on the approximate price ratio: Ag Eq (g/t) = Ag (g/t) + 33.48Pb (%) + 49.61Zn (%) + 80*Au(g/t). Intercepts calculated using a 90g/t Ag cut-off and 3 metre internal dilution factor, with highest individual assay results highlighted as included within overall intercept; except where indicated with [+], which is the high-grade breccia zone intersected in BD20017.

Further Exploration

Two diamond drilling rigs are operating at the Bowdens Silver Project and continue to test high-grade silver targets and extensions to the current resource. Due to the success of the current program, expansion of drilling and other exploration activities is currently being planned.

Regional exploration activities, around the Bowdens Silver Deposit, have continued through the March 2021 quarter and in accordance with the Company’s COVID-19 policies. A detailed gravity survey was completed over the Deposit area and surrounds. The increased survey resolution will assist with the interpretation of the controlling structures and possible source intrusives in the area. This data and updated models have aided in targeting for new silver deposits in proximity to the Bowdens Silver Deposit.

For further information refer to ASX releases of 28[th] January 2021 and 19[th] February 2021.

Barabolar Project

During the March 2021 quarter, the Company continued desktop activities on the Barabolar Project, which is located approximately 26 kilometres east of Mudgee in central New South Wales and 10 kilometres northwest of the Company’s Bowdens Silver Project (refer Figure 3).

Due to the COVID-19 pandemic the planned drilling at Barabolar had been put on-hold. However, the Barabolar Project remains a compelling target area with a considerable hydrothermal footprint, and the Company is continuing with desktop studies and application of R&D technologies in this area as it plans for the recommencement of activities.

About the Bowdens Silver and Barabolar Projects

The Bowdens Silver Project and Barabolar Projects are located in central New South Wales, approximately 26 kilometres east of Mudgee (see Figure 4). The consolidated project area comprises 2,007 km[2 ] (496,000 acres) of titles covering approximately 80 kilometres of strike of the highly mineralised Rylstone Volcanics and underlying sediments, intrusions and volcanics of the Macquarie Arc. Multiple target styles and mineral occurrences have potential throughout the district including analogues to Bowdens Silver, high-grade silver-lead-zinc epithermal, volcanogenic massive sulphide (VMS) systems and copper-gold targets.

Bowdens Silver is the largest undeveloped silver deposit in Australia and one of the largest globally with substantial resources and a considerable body of high-quality technical work completed. The projects boast outstanding logistics for future mine development.

Tuena Gold Project

The Tuena Gold Project is located 80 kilometres south of the city of Orange in New South Wales (Refer to Figure 5).

The Tuena area was the scene of a historic gold rush, with gold extracted from several narrow high-grade gold reefs over a regional trend greater than 5 kilometres of strike length. The Company has completed reconnaissance mapping, rock sampling and soil geochemistry; as well as flown a detailed magnetic survey. The Company has defined >15 individual zones with anomalous gold in soil sampling associated with historic workings. Rock samples have also returned highly anomalous gold results at Peeks Reef (up to 76.4 g/t Au in rock sampling), Cooper & McKenzie and the Eastern Prospects (Refer to release dated 23[th] October 2019).

During the December 2020 quarter, the Company commenced a 20 hole 4,000 metre drill program designed to test beneath several of the historic hard-rock gold workings and associated geochemistry anomalies along an extensive 5.4 kilometre by 1.5-kilometre shear complex within EL8526 (refer to Figure 5). In addition, two targets, at Lucky Hit South and Markham’s Prospects, have been identified with both gold and base-metal pathfinder signatures. Both prospects adjoin historic workings at Lucky Hit and Markham’s Hill respectively and are clearly defined by soil chemistry with anomalism of silver, bismuth, lead, tellurium and gold (refer release dated 19[th] May 2020). These targets are being tested for bulktonnage gold mineral systems and have a comparable signature and scale to the McPhillamy’s Gold Project (Regis Resources) located north of the Tuena Gold Project.

During the March 2021 quarter, final drill assay results were returned. Drilling has encountered multiple potentially mineralised structures beneath historic workings comprising quartz and carbonate veining with or without pyrite (iron sulphide). A substantial intercept of 4 metres @ 6.88 g/t gold (from 98 metres) , with a peak assay of 25g/t gold over 1 metre was intersected in TRC20010 beneath the Garnet Mine Prospect (refer to Figure 6) with multiple intercepts < 0.5 g/t gold returned in TRC20009 and TRC20010 suggesting that other gold bearing structures are proximal.

Further gold mineralisation was received from assays for holes around Peeks Reef in the northwest of the area and between Peeks Reef and Garnet Mine. TRC20019 intersected 10 metres @ 0.53 g/t gold (from 36 metres) including 3 metres @ 1.5 g/t gold (from 36 metres) and 1 metre @ 2.67 g/t gold (from 72 metres), while TRC20017 intersected 1 metre @ 1.62 g/t gold (from 133 metres) at Eastern prospect.

Alteration associated with mineralisation consists of sericite–silica–carbonate with the project area mostly metamorphosed to schist and phyllite. The distribution of gold mineralisation suggests that a substantial hydrothermal system has affected the area. Results from this initial program are being collated and will guide follow-up drilling to test the extents of gold encountered.

This program represents the first modern drilling to be completed in the Tuena project area. However, in recent years there have been substantial gold discoveries made along the strike of the Copperhannia Fault including the McPhillamy’s deposit to the north of Tuena (Regis Resources) and the Cullarin discovery to the south (Sky Metals).

About the Tuena Gold Project

The Tuena Gold Project is a regional exploration project that consists of a four exploration licenses covering 747 square kilometres. The project is 100% owned by Silver Mines Limited and is located in the Southern Tablelands of New South Wales, 180 kilometres west of Sydney, 80 kilometres south of Orange and 150 kilometres southwest of the Company’s primary assets the Bowdens Silver Project and the Barabolar Project. Tuena was the site of a mid-1800s alluvial and hard-rock gold rush. A cluster of historic workings closely associated with the major Copperhania Thrust Fault extend over an area approximately six kilometres by four kilometres. The Company is targeting the region for large structurally controlled gold deposits analogous to the nearby McPhillamys Gold Deposit.

Research and Development and NSW New Frontiers Cooperative Drilling Grants

The Company has an active research and development (“R&D”) program to better map and understand the Permian volcanics and basement Palaeozoic (Ordovician and Silurian) rocks of the Company’s exploration licenses. The R&D programs are on-going and have, over the past three years, involved collaboration between Silver Mines’ researchers and researchers from the University of Technology Sydney, the University of New South Wales and Macquarie University. Several industry consultants and data collection contractors have also assisted in analysing and providing base datasets for the R&D program.

The R&D project involves developing innovative new technology and processes, which have been applied to geological studies on the Bowdens Silver Deposit and particularly the basement rocks and the search for a porphyry source or feeder structure. In addition, research has been applied to the Barabolar Project area and elsewhere in the Company’s portfolio including Tuena. The Company has developed and continues to develop new technologies for multivariate geochemical analysis; automated mapping of geology from geochemistry data; and predictive geochemistry modelling using machine learning techniques. These R&D programs have developed further hypotheses for mineralisation in areas such as basement rocks beneath the main volcanic host at the Bowdens Silver Deposit; Bowdens northern and north-westerly extensions; and several targets in the Barabolar Corridor including the Cringle prospect area. Much of the Company’s exploration drilling is considered as a test of hypotheses and targets developed under these R&D programs.

During the March 2021 quarter, the development and testing of the machine learning predictive geochemistry technology and integration with recently acquired gravity data continued. This work has produced an integrated geology, geochemical and geophysical model of the Bowdens Project. This model is being used for detailed targeting of potential feeder zones and/or magmatic sources to the Bowdens Silver epithermal mineralisation. The current drill programs at Bowdens are on targets generated from this work and based on the integration of technologies and data. The Company is now establishing programs to test its machine learning technologies on targeting outside of the Bowdens-Barabolar district to establish if such technologies have transferable applications to other geological domains. In particular, the Tuena Gold Project, with a multi-element association of gold mineralisation at surface along with complex structure, is being used as a further test site with drill targets associated with multi-element anomalism being generated, in part, by these technologies.

		•Mineralisation is overall shallowly dipping (~15 degrees to the north)
		with high-grade zones preferentially following a volcanic dome. There
		are several vein orientations within the broader mineralised zones
		including some areas of stock-work veins.
		•The mineralisation reported in this release is hosted in the main
		Rylstone Volcanics which unconformably overlie the Ordovician
		Coomber Formation (sediments). The mineralization reported in this
		report is related to Bowdens and represents a higher-temperature
		zone.
		RC Drilling – Tuena:
		•The Tuena Project consists of Devonian and Silurian age volcanics
		and sedimentary rocks which have been regionally and locally
		deformed during the Tabberabberan orogeny. This has resulted in
		regional folding and multiple generations of faulting associated with
		the major Copperhannia Thrust on the western side of the tenement.
		•Mineralisation is defined by the existence of historic shafts and audits,
		and can be observed at surface as structurally controlled shear or
		vein systems hosted within deformed sediments and volcanics.

Data	• In reporting Exploration Results, weighting averaging techniques,	Diamond Drilling – Bowdens:
aggregation methods	maximum and/or minimum grade truncations (e.g. 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.	•Intersection calculation are weighted to sample length. The average sample represents 1 metre of drill core. •Reported intersections are based on a cut off of 90g/t silver with no internal dilution factors •No top cutting of data or grades was undertaken in the reporting of these results.
	• The assumptions used for any reporting of metal equivalent values	RC Drilling – Tuena:
	should be clearly stated.	•Intersection calculation are weighted to sample length. All samples
		represent 1 metre lengths.
		•Reported intersections are based on a cut off of 0.1g/t gold with no
		internal dilution factors
		•No top cutting of data or grades was undertaken in the reporting of
		these results.
Relationship	• These relationships are particularly important in the reporting of	Diamond Drilling – Bowdens:
between mineralisatio n widths and intercept lengths	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 (e.g. ‘down hole length, true width not known’).	•Mineralisation is both stratabound and vein hosted. The stratigraphy dips moderately to the north within the volcanics and moderately to the west in the basement units, while the majority of mineralised veins dip west. Some individual veins intersected were sub-parallel (~10 to 20 degrees to core axes). However, given the stratigraphic controls on the zone, the drilling width is estimated to be 100 to 140% of true-
		width for stratabound mineralized zone.
