Galena Mining Limited announced that the construction progress at its Abra Base Metals Mine (Abra or the Project) has reached 58% complete on 31 March 2022. Overall project progress continues to remain in line with project schedule for the production critical areas of mining and processing. The processing plant EPC has reached 61% complete by project spend.

The processing plant infrastructure work completed by work commitments is slightly ahead of the most recent planned work schedule by the end of March. In bulk earthworks the Tailings Storage Facility (TSF) work stopped whilst a technical review was completed on the proposed TSF, investigating the material suitability and availability for dam wall construction. That work along with the revised design work was completed in March.

Civil contractor pricing and availability is currently being evaluated prior to the recommencement of the TSF. The final works package associated with the remaining non- processing infrastructure which is not production critical has been finalised and that work has commenced. Underground mine development has reached the 1,395mRL which is 155m below the surface and 82m above the orebody.

The decline is currently heading in a southerly direction and is approaching the location of the first underground drilling platforms. These drilling platforms will enable commencement of grade control drilling in the first production levels of the mine. When this drilling commences, opportunity may arise to enable the company to carry out some further resource definition and exploration drilling. Raise drilling is scheduled to resume in late April and the primary exhaust fan is scheduled to be installed in early May.

Abra has been advised of three revised delivery times for the overseas equipment supply for the processing plant. The construction of the secondary and tertiary cone crushers has been completed and these have commenced shipping. The arrival date for these crushers have now been confirmed as the end of May.

The primary Jaw crusher has arrived on site. The thickener arrival date has improved from the previous month and will arrive in early May. The grinding mill shipments comprising of 4 separate shipments remains as previously indicated.

Shipment 1 has arrived on site (mill sole plates). Shipment 2 has commenced (lubrication system). Shipment 3 and 4 have not changed from the previous advice.

The regrind mill shipping date has been confirmed as arriving in early September. None of these delivery changes are expected to cause any overall construction schedule delays.
