Timberline Resources (TBR.V) recently put out the first (partial) assays from the first twinned diamond core hole into the Water Well Zone.
The results were way above my expectations.
But first things first. Lets look at what a Twinned Hole is and what the context is in this case…
Well Timberline Resources suspected that RC drilling might have UNDER-estimated the actual grades in the Water Well Zone due to the fine gold being partially lost during recovery of the rock chips. In other words it was believed that when using RC drilling some of the gold got washed away by the water used to get the rock back up the hole. In order to test this thesis the company drilled a Diamond Core hole (the twinned hole) right next to an RC hole in order to compare the results. If the Diamond Core, which pulls up much more intact rock samples, proves to be higher grade then one can surmise that gold has indeed been lost (and grades been under-stated) in the RC holes. Well it turns out that this suspicion looks to be more than correct given that the Twinned Diamond Core so far has produced grades 5.8 TIMES higher than the nearby RC hole...
The RC hole produced a gram-meter intercept of 39 while the nearby Diamond Core hole producer a whopping 140 gram-meter intercept. Also note that there are still more assays to come from this hole which means that it is likely to end up being even better given that the last assayed part came in at 7.56 g/t Au.
This might be a game changer for Timberline and the Eureka project.
Why? Because most of the drilling so far on the project, and especially the Water Well Zone, has been done with RC drilling. In other words I think there is a good chance that the existing resource as well as all the RC drilling done at the Water Well Zone is actually higher grade than anyone thought up until now.
