Lo Duong Khanh, chairman of the Tam Thai Commune People's Committee, said the discovery highlighted the area's largely unexplored natural resources.
The commune will work with the Tuong Duong Protection Forest Management Board and relevant authorities to conduct a detailed survey of the cave, examining its geological features, landscape and natural value, Khanh said.
Based on the findings, local authorities will develop appropriate protection measures to minimise impacts on the cave and preserve its current condition.
If conditions permit, the area could also be studied for potential ecotourism development linked to forest conservation, officials said.
