From this first mine you should make iron rods. They will find more mines, since when prospecting with Woo-Woo you will only find mines with all nodes in range 25 +- 5 on each alchemical component. Iron rods let you find nodes with each alchemical component by up to 10 lower or higher than rod's component. Woo-Woo wands are always 0 purity with all components equal 25, so they will only show mines with component between 20 and 30. Iron rod with all components of 25 will let you find nodes with each component between 15 and 35.
Anyway, once you got your first iron rod use it to find some node. Once you find it, use woo-woo wand to check if you can see this node with it. If not then it means that at least one component is either below 20 or above 30, which brings you closer to higher purity. Then just build another mine, make another rod and so on...
The more rods you have the more accurate your results may be.
