Extinct volcanoes will never erupt again... I am not sure what stage but this is the best info I can give you.
Volcanic stages, from least likely to most likely to erupt, are typically ranked as follows: extinct (no chance of eruption), dormant (unlikely but possible), restless (showing signs of activity), and active (currently erupting or likely to erupt). The ranking is based on the volcano's historical behavior, monitoring data, and signs of increasing activity.
Volcanoes typically go through four main stages: the active stage, where eruptions occur regularly; the dormant stage, where a volcano has not erupted for a significant period but may still erupt in the future; the extinct stage, where a volcano is unlikely to erupt again due to a lack of magma supply; and the formative stage, where volcanic activity is just beginning and the structure is still developing. These stages can vary in duration and may not always follow a linear progression.
Active Stage: Volcano erupts, releasing lava, ash, and gases. Dormant Stage: Volcano is not erupting but can become active again. Extinct Stage: Volcano is unlikely to erupt again in the future.
There is the active stage (which explodes from time to time), the dormant stage (which is expected to erupt but might not), and the extinct stage (which means no more explosions).
Active, dormant, and extinct.
active- or live volcano is one that is erupting or has shown signs that it may erupt in the near future dormant- volcano to awaken in the future and become active extinct- or dead volcano is unlikely to erupt again

it is the stage wen the volcanoe is sleeping but can still erupt in the future
A volcano that is not currently erupting is typically considered to be in the "dormant" or "inactive" stage. This means it has not erupted for a significant period, but it could potentially erupt again in the future. In contrast, a volcano that has not erupted in recorded history is often classified as "extinct."
An extinct volcano is one that scientists believe will not erupt again. That is because the volcano no longer has a magma supply. There are many volcanoes that are considered extinct on the Hawaiian islands. Exactly when a volcano has become extinct can be difficult, if not impossible, for scientists to determine.
At their early stage mostly during the youthful age.
Mount Pirongia is classified as an extinct volcano, meaning that it has not erupted in the past and is not expected to erupt again in the future. Its last activity occurred over 1.6 million years ago.
at that stage it is unlikely you can preserve it.
