The Manaila Polymetallic Mine (“MPM”) has remained on care-and-maintenance during the period and the Company is actively engaged with new investors to support the restart.
The Company was granted the Manaila Carlibaba Exploitation License to 29 October 2025. Manaila-Carlibaba represents a highly attractive development opportunity for Vast – comprising a previously producing mine now on care and maintenance, together with a sizeable and highly prospective land package which has the potential to host an open pit and high-grade underground mine. |

Summary:
The local geology at MPM comprises lithologies of the lowermost units of the TG4 and the uppermost units of the TG3 formations of the Tulghes Group. They comprise the following:
•TG4 Formationo
- Basque Formation
•TG3 Formationo
- Fundu Moldovei Membero
- Morosan Member
The Morosan Member of the TG3 formation is a rhyolitic volcano sedimentary sequence comprising alternating sequences of quartz sericite schists -\+ chlorite -\+ graphite and metamorphosed rhyolites. The top of the sequence is marked by the development of a chlorite sericite schist with porphyroblasts of albite. The contact between the Morosan Member and the overlying Fundu Moldovei Member marks the development of the sulphide mineralisation at MPM.
The Fundu Moldovei Member of the TG3 Formation is represented by a predominantly metamorphosed rhyolites and quartz-sericite schists, which vary in thickness. The top of the TG3 Formation is marked by the development of the polymetallic mineralisation associated with the mineralisation located within the Putnei – Prasca valley (Lesul Ursului,Fundu Moldova). This mineralised zone occurs along the northern boundary of the current exploration perimeter.
The Basque Member of the TG4 Formation is present in the north western of the exploration perimeter and is comprised of a cyclic alternation of various blastodetrital quartzites and phyllitic lithologies. Thin beds of acid metatuffs occur in the u ........

Summary:
Ore mined and destined for processing is transported approximately 32 kilometres by road in 8m3 tipper trucks from the open pit to the metallurgical plant located in the village of Iacobeni. Waste material from the metallurgical plant is then transported 14 kilometres by road to a disused manganese open pit which has been permitted as a Tailings Storage Facility and islined with a HDPE liner. Run of Mine waste or overburden is dumped on a waste rock dump facility on site within 1.0 kilometres of the open pit.
The mine currently owns an electric face shovel with the bulk of the excavators, tipper trucks and articulated dump trucks (“ADT’s”) being operated by a haulage contractor. In addition to the open pit excavation, there are two levels of underground workings. The underground workings are exploration drives driven along the strike length of the orebody in a northwest – southeast direction. Access is via adits although two entrances have collapsed. The third adit has been removed by mining activities in the open pit.
