This could be the start of something.
Saw the press release and this seems very interesting as it's very rare to find diamonds in the sand like this. But after research on their site it seems they have been searching for years and may now be finally getting close.
They'll likely need an expert in climate to be a able to judge how and where these diamonds washed up on the beach.
But it seems this team is going about things step by step and with all big diamond discoveries, it will just take constant effort and a stream of constant ideas.
What's interesting here is that the diamond bearing kimberlites (source) has yet to be discovered, so as a player you are getting in before the discovery. It's also appealing that their latest releases are showing exploration activity with some results.
Good Luck to All (of it)
