The Geological Survey of Victoria has been mapping old mines across the state.

In short, the project used special technology to find old mines.

The project found about 230,000 old mining spots on public land.

Before, people only knew about 30,000 of these spots.

What happens next?

The final report will come out soon.

There are many old gold mines hidden under the ground in Victoria.

In 1851, Victoria became a separate state and people found gold, leading to many immigrants coming to seek their fortune.

This led to many changes and a lot of gold hunting, which has left many marks on the land.

A four-year project used a special method to look at the Earth's surface and found many more old mines than expected.

Sometimes, holes open up after heavy rain, and these are often from old mines.

The project looked at areas around Golden Plains, Melbourne, and other places.

A small plane with special equipment flew over these areas to find old mines and tunnels.

The equipment sends out laser beams that bounce back, helping to make a map of the area.

The laser beams work like a kind of echo location but with light.

The data from the laser beams is used to make a 3D map of the area.

This map can show things like trees and buildings, which are then removed to reveal the ground below.

Sometimes, sinks or holes in the ground can indicate where old mines are.

The first part of the report found that the automated program was very good at finding old mines.

But it was not as good at telling the difference between different types of mines.

The data will be useful for firefighters, emergency services, and people who manage the land.

The project leader said the data gives a better idea of what needs to be taken care of.

She also said the real number of old mines could be even higher.

The final report will be out soon.

Many people have looked for treasure over the years.

A full-time prospector was not surprised to hear about the many old mines found.

He said some of the data was already being used by people looking for gold.

He loves finding old mines and thinks they are very interesting.

All prospectors dream of finding a lot of gold, and they follow in the footsteps of those who came before.

The prospector has explored many old mines in Victoria and New South Wales.

He said the old mines are an inspiration to modern prospectors.

The old miners were very clever and built many kilometers of water pipes and tunnels.

The prospector said that getting lost is a bigger danger than the old mines, but it's still important to be careful.

A woman and her dog were rescued after falling into an old mine shaft.

Here are more news stories from regional Victoria.

There are many hazards from old mines.

Many people and animals have been rescued from old mines.
