在萨斯喀彻温北部森林中赤杨埘枝和树丛含金量有比其它植物多的趋向。赤杨树不含氰,因此当它被灰化时在易挥发的氰化物中就可将金富集起来而不损失其金属含量。采自矿化带的样品在长度为50cm的最富的树枝灰份中的金含量为50mg/t以上。本底值估计为10mg/t。在没有赤杨树时,可以利用其他植物, In the northern Saskatchewan forests, there is a tendency for more almond branches and trees in the forests than in other plants. Alder does not contain cyanide, so it can be enriched in volatile cyanide when it is ashed without losing its metal content. Samples taken from the mineralized zone had a gold content of 50 mg / t or more in the richest branch ash with a length of 50 cm. The background value is estimated at 10 mg / t. In the absence of alder, you can use other plants,
