I think Goldmines Movies will be a new channel maybe for airing newer bollywood movies or maybe airing retro bollywood movies. Let us wait for more details. Could also be that Dhinchak 2 is being rebranded as Goldmines Movies and will air mix of bollywood movies + dubbed movies.
Goldmines Bollywood may continue to be available with slight changes in content strategy
