Conditions Precedent met for Agreement to Acquire Sa Pedra High Grade Gold and Silver Project With Historical Resource
HIGHLIGHTS:
-
The Conditions Precedent included in the Option Agreements entered into on 28 May[1] over the advanced high-grade gold and silver Project in Sardinia, Italy, named the Sa Pedra Bianca Project, have been satisfied or waived.
-
Marquee now enters into the Option Period, during which it will conduct exploration activities aimed at confirming the historical mineral resource of 1.65Mt @ 7.06 g/t Au and 29.7 g/t Ag for a total of 376,140oz gold and 1.58Moz silver[1] , testing numerous other historical exploration targets as well as several others that have been newly identified during the due diligence process.
-
Meetings held last week between Marquee and local and regional Sardinian government representatives have positively affirmed that Sardinia is in step with the Italian national government’s new directive to promote and facilitate mining activities in Italy.
-
Based on its due diligence, Marquee considers the Project to have exceptional upside with real potential to become a 1Moz+ gold Project.
Marquee Resources Limited ( “Marquee” or “the Company” ) ( ASX:MQR ) is pleased to announce that the Conditions Precedent to the two interlinked Option agreements entered into with two parties to acquire the advanced high grade gold and silver Project in Sardinia, Italy, named the Sa Pedra Bianca Project, have been met or waived and the Option Period of 12 months has now commenced.
MQR believes that its decision to enter into the jurisdiction of Sardinia is extremely well timed for the Company and its shareholders. A ministerial decree to adapt the Italian legislation of the mining sector to conform with EU regulations was approved in the Italian Council of Ministers on 20 June 2024. It includes new simplified procedures for approving exploration and mining activities. Whilst the focus of a new mining decree are the 34 critical minerals designated by the EU, it is likely that the new laws will have flow-on benefits for exploration and mining activities focussed on other minerals, such as gold and silver.
Marquee Executive Chairman, Mr Charles Thomas, commented:
“After the Company's Chief Technical Officer (CTO) Dr James Warren and myself visited the Sa Pedra Project last week to complete the final due diligence checklist items, I am extremely pleased to announce that the Sa Pedra Bianca Gold and Silver Project has passed our rigorous due diligence process and we have now entered into the Option Period with the vendors Dr Manca and Mr Spencer. We are extremely

excited to now begin properly evaluating the historical resource and the enormous exploration upside potential that exists at the Project.”
“I am furthered enthused that this trip has highlighted multiple new areas at the Project that require field testing, with our belief that the Sa Pedra Project has the real prospect of being a 1Moz+ gold Project for the Company.”

Figure 1 – Map showing the regional geology of the greater Osilo area.
The Project is held under an investigation permit that allows low impact exploration activities. It encapsulates the Bunnari, Pedra Bianca, Sa Pala (de Sa Fae), Fieldies (partially) and Pala Edra gold bearing quartz veins. An exploration permit will soon be applied for to allow full exploration activities including drilling. It is expected to take 4-6 months for the application process to be completed.
During this period, Marquee will focus on various exploration activities, including:
-
Retrieval and analysis of as much historical data and information as possible from various sources including archives held by various Sardinian government bodies and geologists who have previously worked on the Project. Previous exploration work included comprehensive soil and trench sampling, drilling, geophysics, mapping, mine planning and various associated studies to assist in applying for a mining concession, including hydrology and environmental studies.
-
Undertaking various low impact exploration work (e.g. soil geochemistry, mapping, geophysics, structural interpretation), as permitted by the existing investigation permit.

- Planning an engagement strategy to govern interaction with Sardinian regulatory authorities, local communities and other stakeholders. The key tenet of the strategy will be to advance and develop the Project by applying best practice ESG principles and in a manner consistent with European and Italian principles for extracting sustainable raw materials.

Figure 2 – An historical geochemical map showing the anomalous gold signature from soil sampling and the locations of the main gold and silver bearing vein systems within the greater Osilo area.
During the due diligence process, the map shown above in Figure 2 was obtained. It provides compelling evidence of the many anomalies located within greater Osilo area that have yet to be drill tested, with the previous explorer only drill testing 5 of 22 veins that had been mapped on surface. It is very likely that there are also multiple targets that do not outcrop, as was evidenced by the Bunnari prospect, where drilling of the outcropping vein also intersected a second, deeper sub-surface high-grade vein.
Following the grant of the research permit and before a decision to exercise the Options needs to be made, a Reverse Circulation (RC) and/or Diamond drill (DD) campaign will be undertaken with the objectives of providing confidence in the results achieved from historical drilling and to test down dip and extensions of previously drilled veins as well test new veins for mineralisation.
