Hi Rios,
I've gone back and actually read your report now. Should have done that properly first
The recommendations your geo lays out look pretty good. I'd just follow those for now.
From your trench assay results it looks like you've got anomalous gold (0.2 g/t +) across the zone of your highest grade result. That's to be expected adjacent to a reef but wouldn't extend too far into the country rock.
I take it the material you trenched is pretty much 'in situ', or does it look transported? (ie. moved down the slope a bit) If its in situ then that high grade location would be the extended position of your reef. Does that match up about right? You could drill a hole or two into the down-dip position to confirm or you could just move about 5-10m to the footwall and sink your shaft there down into solid bedrock then drive NW to intercept the reef. If you're intending on developing quite a show, always put your infrastructure in the footwall to preserve it best.
What's the dip on the reef from the mines to the NE and is the dip fairly consistent between them?
Does the reef pinch and swell?
The answers to these questions should guide the placement of the shaft and the consistency of grade you can expect once you hit your reef.
If the dip is mid to low angle, you could just get away with an underlay shaft straight down along the reef, which would take care of access and haulage.
Good luck and keep us updated on how you go!
