The L&M Group will be hosting an open mine day at its gold mine, off McPherson Rd, from 9am onwards.
L&M Group chief financial officer Shirley Herridge said people would be able to see the mine in full operation, with access to the edge of the pit face which could not normally be seen.
Loaders, trucks and the dredge, one of the largest in New Zealand, would also be operating during the open day and staff would be on site to talk to people about the mine.
Employing about 35 people and operating 24 hours a day, the mine had about 260ha of mineable land.
The mine, which had been operating since 2009 and was about halfway through its life span, did not have an open day last year due to issues with the dredge.
Since then, the mine had undergone ''a lot'' of modifications and would be different from what was observed on previous open days, Miss Herridge said.
Earnscleugh Community Society secretary Louise Joyce said the day would be an opportunity to see a dredge in action.
''It is an alluvial gold mine with a dredge, which is pretty unique. It's a chance for people to have a look at that plus enormous earthmoving machinery.''
The last dredge finished operating in Central Otago in about the 1960s, she said.
A total of about an ounce of gold from the mine would be available for purchase in small amounts at the Earnscleugh Hall, which would also have static displays of machinery and equipment at the mine, and serve morning and afternoon tea.
Proceeds from the day would go to the Earnscleugh Community Society.
''L&M have been extraordinarily generous: they pay for the Lions [who run a barbecue], they also pay for supplies at the hall. That's ... good of them,'' Ms Joyce said.
It's support was part of building relationships with the community.
Miss Herridge said the mine open day, which the group tried to hold once a year, was its way of doing something for the local community.
Ms Joyce said the open day today would be the third held by L&M at the mine.
About 1300 people visited the mine during the last open day.
