Nah I understand that its not 43m unbroken, most holes have multiple intercepts in the one hole, its just they never list whats inbetween.
"Wallrock alteration has been recognized a valuable tool in exploration, because the alteration haloes around many deposits, are widespread and easier to locate than the orebodies themselves. At various distances from a vein, the conditions of temperature and chemistry are usually different. As a result of this different types of alteration are likely to be produced simultaneously at various distances from the vein or fissure. For example, in the outer fringes of the alteration zone, the ferromagnesians may have been slightly hydrated while the interior zone was being silicified or sericitized, and the intermediate zone argillized. The product of this is a zoning of different alteration products arranged symmetrically around the central vein. In some deposits this zoning is conspicuous and may be an excellent guide to ore"
So im just wondering if its a good thing or not, ill ask one of the geos at work tomorrow.
