Ecuador and general reseach., page-31

Re the AI bots, I think you are right about the "scary" part. In some situations, the "good" part I am not so sure about.

What is the source of that information re BHP? It is completely at odds with everything I have read in the past.
There is no STM ASX announcement from March 2019 regarding any agreement with BHP.

On the contrary according to the Sunstone Metals website:
https://www.sunstonemetals.com.au/site/projects/bramaderos-gold-copper-project/overview
"The Bramaderos Project is held by La Plata Minerales (‘PLAMIN’) of which Sunstone metals has a 87.5% ownership and Cornerstone a 12.5% ownership. Sunstone is fully funding all activities at Bramaderos and Cornerstone is loan carried to production. Sunstone is also managing all exploration activities at Bramaderos through its Ecuadorian team."

Specifically regarding the Bramaderos project JV terms:
https://www.sunstonemetals.com.au/site/projects/bramaderos-gold-copper-project/joint-venture-terms
"Sunstone holds an 87.5% interest in the Bramaderos project earned through an earn-in joint venture which commenced in 2017. The project is held within the Ecuadorian company La Plata Minerales S.A. or ‘PLAMIN’.Sunstone is fully funding and managing all exploration activities at Bramaderos.Joint venture partner Cornerstone's 12.5% interest is loan carried by Sunstone through to the start of commercial production and repayable at Libor plus 2% out of 90% of Cornerstone's share of earnings or dividends from the Bramaderos project.Approximately 2/3 of the Bramaderos concession surface area is subject to an underlying 2% net smelter returns royalty (NSR) in favour of a third party (the 2% NSR). A $50,000 annual advance royalty is payable on and after the first anniversary of the delivery of a Positive Feasibility Study. One-half of the 2% NSR may be purchased for $3 million."

Admittedly the STM website may need to be updated given what has transpired with Cornerstone and Solgold, but I would tend to think the STM website is likely to be a lot more accurate as to the Bramaderos JV terms over an AI generated word salad.

If there is an agreement between BHP and Sunstone I will be happy to read about it. Where's the ASX announcement?
