JUNE 2022 QUARTERLY ACTIVITIES REPORT
Alicanto set for more growth at Sala zinc- silver-lead project after posting outstanding maiden Resource and strong drilling results
Mineralisation is open in all directions and drilling is ongoing
HIGHLIGHTS
- Independent Inferred Mineral Resource Estimate (MRE) of 9.7Mt @ 4.5% Zn (Eq) at the 2.5% Zn (Eq) reporting cut-off1 at Sala Project in Sweden
- Importantly, this includes a high-grade core from surface of 4.5Mt @ 6.0% Zn (Eq) at the 4.0% Zn (Eq) reporting cut-off1
- The outstanding result was achieved in just over a year since Alicanto acquired Sala
- The Resource is considered to be of a Stage One nature, with substantial growth expected given the mineralisation is open in all directions and drilling is ongoing

Sala Zinc-Silver-Lead Project (Sweden 100%) | |
Sala, which is located 100km from Alicanto's Greater Falun copper-gold project and 50km from Boliden's | |
only | operating Garpenberg Mine, was once Europe's largest silver producer. |
When mining finished at Sala in 1908 it had produced more than 200Moz of silver at an estimated average grade | |
of 1,244 g/t and grades reported as high as 7,000 g/t. Sala also produced over 35,000t of lead at 1 to 2% as well | |
as mined zinc at an average grade of 12%3. | |
The host rocks have been folded and faulted with the underlying metamorphosed felsic volcanics and | |
pyroclastics. The series of shafts along the Sala mineralisation trend in a north-south direction, apparently | |
controlled by fold structures gently plunging to the north. Longitudinal sections indicate that the mineralised | |
zone at Sala (as indicated by mined-out workings) also plunges gently to the north. | |
use | Sala was re-opened in 1951 for a short time and upon closure it was believed that the mineralisation ceased at |
the 320m level. However, a small drill program undertaken in 2012 demonstrated that the Sala mineralisation | |
continues to plunge to the north from the historic mine area and remains open and untested to the north and | |
down-dip. | |
In July 2022, the Company announced a maiden JORC 2012-compliant Inferred Resource at Sala. The Resource | |
estimate, which was independently estimated by leading Perth-based Cube Consulting, was based on the | |
previously reported data by Alicanto which has included over 20,771m of diamond drilling completed since the | |
personal | acquisition of the project in February 2021. |
The Company delivered the maiden Resource in a little over a year since acquisition, with the mineralisation | |
system remaining open for further growth both at depth below the Prince and Sala Lodes and from surface along | |
the prospective lithological horizon. | |
The reported Maiden Resource comprises a total of 9.7Mt @ 4.5% zinc (Eq) containing over 311,000 tonnes of | |
zinc, 15Moz of silver and 44,000 tonnes of lead reported at the 2.5% Zn (Eq) cut-off.1 | |
Included in the Maiden Resource is a coherent near surface high-grade breccia zone dominated by semi massive | |
sphalerite which contains the majority of 4.5Mt @ 6.0% Zn (Eq) containing 8.5Moz of Silver and 201,000 tonnes | |
of Zinc reported at the 4% Zn (Eq) cut-off. The Company is continuing to target near surface and down plunge | |
extensions of this area with ongoing diamond drilling with further results expected to be released to the Market | |
as they become available.1 | |
The maiden Resource estimate covers the Prince Lode, located immediately to the South of the historic Sala | |
Mine. The Price Lode trends towards the north-northeast and has been defined over 950m of strike and 700m | |
down dip. | |
For | During the quarter the Company drilled 4,570m of diamond core drilling concentrating on the Prince Lode, Sala |
extensions and a new antiform structure parallel to Sala. | |
The Prince Lode, which is a zinc-dominated mineralised zone located immediately to the south of the historic | |
Sala Mine, was the main area of drill testing by Alicanto during the quarter investigating the southern extensions | |
of the Prince Lode. Drilling returned the following exceptional results (Refer 3 May 2022 and 28 June 2022 2): | |
• 1.7m @ 132 g/t Ag, 1.4% Zn, 1.9% Pb, from 260.25m and | |
• 2.8m @ 22 g/t Ag, 12.7% Zn from 516.9m and | |
• 2.5m @ 173 g/t Ag, 1.6% Zn, 2.8% Pb from 553.9m and | |
• 4.1m @ 14 g/t Ag, 4.5% Zn from 587.2m in SAL-228 | |
• 2.9m @ 46 g/t Ag, 1.3% Pb from 512.63m (including 0.5m @ 177 g/t Ag, 5.9% Pb from 512.6m) | |
• 2.5m @ 54 g/t Ag, 0.4% Zn, 0.3% Pb from 598.1m | |
• 3.3m @ 31 g/t Ag, 0.6% Pb from 625m |

Drilling also concentrated on the continuation of historic Sala mine, which sits immediately to the north of the Prince Lode. The Sala Lode, which is a Silver dominated, zone trends in toward the north-northwest and has been defined over 350m of strike and 485m down dip. Previously reported drill results from the Sala Lode include (3 May 2022 and 28 June 20222):
- 3.8m @ 2.6% Pb, 653 g/t Ag,
- 1.9m @ 0.6% Zn, 164 g/t Ag, 2.3% Pb
- 1.3m @ 110 g/t Ag and 1.5% Pb
- 3.3m @ 3.6% Zn, 142 g/t Ag, 2.6% Pb
- 3.9m @ 53 g/t Ag, 0.7% Pb
- 0.4m @ 242 g/t Ag, 2% Pb
Drilling during the quarter also intersected a highly mineralised north west trending antiform structure, 200m to the south-west of the Sala Mine. The structure is interpreted to be a parallel mineralised structure to the Sala Mine. The Sala Mine orebody itself is hosted in a north west trending synform and associated fault structure with high grade mineralisation concentrated around the hinge of the fold and fault intersection.
The new antiform structure include drillhole SAL22-26, which intersected a shallow (120m from surface) massive sulphide zone of sphalerite and galena with native silver:
- 4.7m @ 24.4% Zn, 875 g/t Ag and 3.7% Pb from 249.4m (3 May 20222)
Figure 2: Massive sulphides intersected in Drillhole SAL2226
This is the first time this fold and associated fault control on high grade mineralisation has been identified in Alicanto's drilling around the Prince lode although it is known to be associated with the mineralisation at the Sala Mine. This structural control on the dominantly stratabound Prince mineralisation is an exciting development for the project as it not only provides a vector for targeting these zones of structural enrichment around Prince but also plays an important role in the regional targeting around the Sala Project with the likelihood of repeated fault and fold structures to the southwest.

The main portion of this material is related to the high-grade breccia zone consisting of massive to semi massive sphalerite, galena and native silver. The high-grade zone forms a coherent near surface zone which remains open. (ASX 23 March, 3 May and 28 June 2022)2
