true depth at a238

Guys I've been wondering about the potential depth of the resource at A238 given they hit an 80m intecept from surface, but it was using a 50 degree angle on the drill.

Clearly the true depth could be more or less than 80m depending on it's formation and I'm sure current drilling will work it out.

But if we have hit the bottom at a 50 degree angle, what true depth do you estimate from the 80m intercept? I'm thinking about 50m but my geometry is a bit rusty.
