WEL does not need to buy back anything... They get a SKP paid ride untill $4 million is spent... with additional funding WEL will have to contribute its share of have further dilution.. No buying back required just their fair share of ongoing contibutions over the $4 million... and so far SKP has provided no update as per the latest financial!

From original NR:

Marum, a Calgary-based mineral exploration company, will incur exploration expenditures of $5 million on the Property during the five year term of the agreement. Marum will also pay consideration consisting of cash or, at Wildcat's option, cash plus shares of Marum. The cash payments to Wildcat over the term of the agreement will be not less than $325,000, to a maximum of $575,000, depending on Wildcat's annual election to replace up to $50,000 per year in cash payments with Marum shares having a market value of twice the amount of foregone cash payment.

After Marum has spent at least $4 million on exploration, Wildcat can elect to retain up to 35% participating interest on a go-forward basis. As an alternative to participation, Wildcat will hold a 2% net smelter royalty in the Property.
