Although I would not be shocked if was well over 100 due to the very complex geology of the grenville province.

(On edit, OK "specimens", not "species". but, why?)
11th Aug 2017 01:26 UTCAlfredo Petrov Manager
Or is that perhaps the number of specimens in the holdings of the Bancroft museum?

But that would mean having to enter all the species again. However until a reasonabe definition for Bancroft area is established that would have to wait. In my opinion a 50 mile radius is not reasonable. I know Goderham (28mi) has some issues with being included in the Bancroft area and I am sure Marmora (40mi), Madoc(43mi), Minden (46mi) and Haliburton (33mi) would as well. I think this is a case of Bancroft trying to make itself bigger (and more important) than it is.

I didn't know that. Can this be done simply by specifying a radius? That would be a very useful function.

Click on pentagon to draw a boundary.
Save as a geojson file to your computer.
copy data (you will probably have to unzip file) to the geospatial field in Bancroft area locality edit
Also click non-hierarchial check box in same area.

There are no species-rich localities in the area. Most localities have less than 20 species, which are repeated over and over.
Andrew,
Please read your so called reference:
" It is especially favoured by rockhounds who have made Bancroft and its “Gemboree” world famous since over 1,600 different mineral specimens have been collected within a 50-mile radius of the village."
They are talking about 1600 specimens not species. Whatever that means.

I've put in a basic circle (ish) for the region. It may need editing, that can be done if you are willing to do it.

How can anybody come up with these numbers. Even as commercial BS this is extreme. I will write to the Bancroft Chamber of Commerce to change these numbers. There is no 50 km radius area in the world that has that many species.

I would have been generous to include Madoc, which would boost the numbers over 200 species.
The mythical Bancroft balloon has been deflated.

Laszlo, please take the time to read the thread completely. It is not my reference I was only pointing out what out in the media and did not believe the number. If you read my post with the link above you will see it states species. The other post where I put a link does say specimens as you stated. The intent was not to point these out as scientific references for mindat.

That helpfully lists '15' species, but out of those only 5 are actually valid mineral names as they are :)
