Abstract
The worn out bits, used in the core-drilling operations carried out in the
Hekimhan Formation, mostly around Karakuz (in 1960), have been returned to their manufacturers.
In this way it has become possible to know the amount of diamond loss and to realise the economic importance of the percentage of core recovery, the size of the diamonds, and the physical
characteristics of bits, in the evaluation of their efficiency. The results have been presented in the
following tables, graphs and discussions.
Best results have been obtained by the relatively cheap, average quality coring bits carrying West African bortz diamonds. More expensive and good quality coring bits with oriented
diamonds did more work; but, because of the small number available, no conclusive results could
be obtained.

Abstract
1960 yılında Hekimhan (ekseriyetle Karakuz mevkii) formasyonu içinde yapılan
karotlu sondajlarda kullanılan elmas kuronların hurda haline gelenlerinin firmalara iadesi ile, bunların elmas kaybı öğrenilmiş ve randıman malûmatının değerlendirilmesinde, karot yüzdesinin,
elmas tanelerinin büyüklüğünün ve kuronların fiziksel özelliklerinin ekonomik önemi olduğu görülmüştür. Bunlar cetvel, grafik ve irdelemelerle değerlendirilmişlerdir.
Nispeten ucuz, orta kaliteli Batı Afrika bort elmaslarını havi kuronlar en iyi sonucu vermiştir. Daha pahalı, iyi kaliteli ve yönlendirilmiş elmasları havi kuronlar da fazla iş yapmış olmalarına rağmen, adetlerinin az oluşu kesin bir sonuç hükmüne mâni olmuştur.
