求翻译：在黑石矿权区，矿层在多个探槽和露头出露。共有60多个钻孔穿透了这些矿层。 可以根据磁化率图来圈定钛铁矿物的最佳勘探靶区。是什么意思？

Tenements in Blackstone, the seam in the trenches and outcrop exposed. A total of over 60 drilling through the seam. According to the magnetic susceptibility Figure ilmenite material to the delineation of optimal exploration target.

Mineral rights in the Black Rock area, ferruginous rock plateaux in more than one probe and surface. There are more than 60 drill holes through the ferruginous rock plateaux. Can be based on susceptibility to define the best titanium iron mineral exploration targets.

In the black quarry power area, the ore bedseam searches the trough in many and appears appearing.Altogether had more than 60 drill holes to penetrate these ore bedseams. May select the ferrotitanium mineral according to the magnetic susceptibility chart the best exploration target area.

In the black stone tenements, seams in a number of the trench and outcrop outcrops. Total of more than 60 more drilling to penetrate these seams. According to magnetic susceptibility map outlining optimal exploration target area of ilmenite.
