"I am pleased to report that the Vares Project remains on schedule and on budget with first concentrate production planned for Q3 2023. Today the Project passed a significant milestone with 50% of project construction now complete. In addition, with 76% of the total construction capital committed, we will continue to address any remaining inflationary and budget concerns.

"In addition to the successful Project development, we are also approaching completion of the year-long confirmation and definition drilling programme at Rupice with exploration drills continuing to step-out along the Rupice Northwest extension. Both programmes are anticipated to increase the life of mine, as all holes have intercepted mineable thicknesses of massive and semi-massive sulphides.

"Our aim is to build a company - and not just a project. We are focusing Adriatic's zero-harm philosophy, prioritising the health and safety of our employees, contractors and host communities. There has been an introduction of new standards, systems and processes, with a particular focus on contractor management.

"With both the increasing levels of employment and the implementation of our community development plan, we are delighted to see the positive economic impacts in the nearby town of Vares and the surrounding communities."

Adriatic Metals PLC (ASX:ADT, LSE:ADT1, OTCQX:ADMLF) ("Adriatic" or the "Company") is pleased to provide an update on the construction activities and drilling at its flagship Vares Project in Bosnia & Herzegovina ("Project" or "Vares Project").

Focus is now shifting to the logistics component of the offtake, with the Company interviewing shipping brokers, forwarding agents and conducting a technical review of the port of Ploce's facilities in December ahead of first exports in 2023.

3.       SCHEDULE

With the Vares Project's construction programme now at 50% completion, the Company remains on schedule for first concentrate production in Q3 2023. All orders for all long lead time items have been placed and deliveries currently tracking to project schedule. A third-party freight services provider has been appointed and overseas deliveries have begun arriving to site.

The Company retains a high level of certainty as to the build time and delivery schedule of its equipment requirements. The majority of equipment orders, including principal long-lead items, are expected within the delivery schedules anticipated in the 2021 DFS. The Company retains sufficient contingencies and will continue to proactively update the market as construction progresses.

4.       FINANCES

The final Project cost estimate remains at $173m, including contingency of $10m.

Of this, a total 76% of capital expenditure excluding contingency is awarded, pending award, or recently quoted, as shown below:

Figure 7: Breakdown of Committed Capital - 23 November 2022

Of the 24% of pricing that is not yet confirmed, approximately half relates to purchases and works to be performed by local contractors in Bosnia, including haul road construction.

The Company's estimated cash balance on 25 November 2022 was $44.4m.

During November the Company successfully completed substantially all of the conditions precedent required to draw down on the Orion financing package, with remaining items to be completed immediately prior to closing. As the Company has a strong balance sheet, Adriatic will defer the drawdown of the stream and senior secured debt to reduce the cost of capital.

5.       HEALTH & SAFETY

Over the past few months Adriatic's focus has been on managing critical risks across an increasing amount of construction activity. There has been an introduction of new standards, systems and processes, with a particular focus on contractor management, throughout the lifecycle of operations.

The Company is developing its emergency and crisis management policies and responses. Adriatic has engaged Technical Rescue International (TRI), a London based company specialising in emergency and crisis management. During the month of October, the following was completed:

•           interviews with all key personnel, contractors and relevant authorities;

•           detailed gap analysis of systems, equipment, capability, and capacity;

•           developed a strategic risk register and emergency risk register;

•           developed a short-term crisis management procedure; and

•           identified key decisions and next steps.

The safety culture programme 'Creating Safe Work' has been finalised and was launched on 14 November with the aim of training the leadership, exploration and mining teams by the end of 2022.

In September Adriatic signed an agreement with Safety Culture to use their iAuditor software. The platform was launched in November and progressive take up will take place over the next 3-5 months, as forms are built within the platform.

6.       HUMAN RESOURCES

As Adriatic continues through construction, headcount has increased to 183 employees and 222 contractors as at 25 November 2022. In Q3 2022 the Company has also exceeded its target of 25% female employees with now accounts for over 28%. Adriatic is committed to creating a sustainable mining company and this is demonstrated through a performance development plan where each employee has their own tailored Individual Development Plan to improve their knowledge and skillset.

In November Human Resources launched an Employee Engagement survey. This will allow Adriatic to gauge morale and establish how satisfied employees are with their roles and workloads. It will also help identify areas where work can be more fulfilling for employees, leading to greater productivity.

The Company continues to provide English language training, with 93 employees currently in the programme. Driving licence training also continues with four employees having successfully completed the training, and one employee is currently attending practical classes. In November culture competence training commenced with the training being delivered in English, Bosnian and Turkish.

7.       GEOLOGICAL DRILLING

The Company continues to progress infill drilling of the Rupice Mineral Resource Estimate ("Resource"), in parallel with continued expansion and infill of the Rupice Northwest discovery. A drilling gap of only 90m currently separates Rupice Northwest from Rupice mineralisation with strong indicators both will connect as drilling advances into the gap zone.

2022 has seen significant success across each programme, resulting in the clear potential to extend mine life and optimise the mine plan, ahead of first production in 2023.

At Rupice, over 7,700m of resource infill and step-out drilling has been completed this year. Rupice results continue to confirm grade thickness and continuity within the existing Rupice Resource. The drilling also highlights that Rupice mineralisation is still to be closed-off up-dip, down-dip and up-plunge (to the southeast). There will also be an update to the Rupice Mineral Resource Estimate early next year.

Rupice Northwest exploration drilling intersected mineralisation with similar tenor, thickness and continuity as seen in the Rupice Resource. Over 7,900m of diamond coring from 26 exploration holes has been completed across Rupice Northwest this year. Significant assays continue to be returned and are pending validatory checks. Results correlate well with logged visual sulphide zones in core. Tight fan drilling is defining a continuous body now more than 250m in strike length, and greater than 160m in width, from 6m to 30m in thickness, moderately dipping to the northeast and plunging moderately to the northwest. The mineralised system remains open along strike, up- and down-dip and no obvious major faulting displaces mineralisation.

Rupice Northwest drilling results to end of November will form the basis of a Maiden Rupice Northwest Mineral Resource Estimate that will be completed in 2023.

Looking ahead, the Company expects to drill through winter, with a continued focus on Rupice Northwest and extension opportunities around the existing Rupice Resource. Closure of the 90m drilling gap separating Rupice Northwest from Rupice is a priority.  

Near-mine exploration will be supplemented by grade control drilling and geotechnical drilling to be completed from underground, providing the basis for optimal mine sequencing and plant feed. 

Underground grade control drilling will commence in early Q1 2023. In addition to providing final grade control information, geotechnical drilling will be completed to inform ground conditions in planned development.

On regional exploration, the ground gravity survey has generated promising results at the Semizova Ponikva (SP1 and SP2) targets as well as at Droskovac, and first pass drilling is planned for next year at these potential Rupice analogies.

8.       SUSTAINABILITY

Adriatic remains wholly committed to its shared prosperity and zero harm philosophy. The Company continue to progress its Environmental & Social Management System (ESMS) with regular environmental monitoring taking place. An update of the environmental and management plan is in process (which also includes stakeholder engagement) and is expecting to be finalised by the end of December 2022.

The ESMS includes an Environmental & Social Incident Frequency Rate mechanism, which amongst other metrics, tracks grievances raised by the community. So far, in 2022, nine grievances have been lodged, mostly related to subcontractor works, and these have all been successfully resolved.

In October increased water monitoring was implemented for Bukovica river in conjunction with the municipal water company, further demonstrating Adriatic's commitment to preserving the quality and flow of water courses in the neighbouring areas.

Figure 8: Water monitoring (November 2022)

Figure 9: Water monitoring (November 2022)

Activities with Alfa Energy have continued, including work on sustainability strategy and calculation expectations of Greenhouse Gases (GHG) during construction works and predictions for the operational phase. Streamlined Energy and Carbon Reporting data collection for 2022 is also in progress. Alfa Energy has also commenced preparing the Life Cycle Assessment (LCA) for the operational phase and this is expected to be completed in July 2023.  As Adriatic moves towards developing a Net Zero strategy, the team is working together with Alfa Energy to determine the location of sites suitable for renewable energy projects. Adriatic recently signed an MoU with Norwegian renewable energy supplier, Emergy, for cooperation on the development of a 30 MW solar facility for direct supply to the Vares Processing Plant.

Adriatic has commenced work on its first Sustainability Report which is planned for release in Q2 2023, and data preparation for the report is in progress. Alfa Energy will provide inputs including GHG, LCA, and positive steps to reach net zero, and data collection is in progress.

Over the past few months, the Community Development Plan has been finalised and activities are underway alongside regular communication with community representatives. In October 2022, the two-year term for members of the Public Liaison Committee (PLC) came to an end. New members have been selected, with representatives from government and non-governmental institutions from Vares, and neighbouring municipalities, Breza and Kakanj. The first meeting of the newly appointed PLC was held on 9 November 2022.

The Adriatic Foundation has supported local projects related to the environment, such as support for the local fishermen association to improve fish stocks and for the local hikers' association to install solar power panels on a mountain lodge that was previously without electricity. In November 2022, the Adriatic Foundation also invited submissions of additional projects related to environmental protection.
