| 1. | 0 | 1 | Topsoil |
| 2. | 11 | 13 | Some green clay + phlogopites - kimbelite breccia? |
| 3. | 13 | 20 | Polymict breccia - felsic gneiss, quartzite, Schist. |
| 4. | 20 | 26 | Decomposed light grey clay abundant - non - kimberlitic. |
| 5. | 26 | 31 | The remainder of the hole (except 94-95m) consists of entirely fariable, quartz, biotite Schist are pink feldspar gneiss in varying proportions. The Schist is generally most abundant. |
| 6. | 31 | 39 | (pfg - pink feldspar gneiss qz - biot = quartz biotite Schist.) |
| 7. | 39 | 47 | 90% qz - biot - Schist, 10% pf gneiss. |
| 8. | 47 | 49 | Small percentage laminated clay - decomposed Schist. |
| 9. | 49 | 59 | 100% pfg |
| 10. | 59 | 62 | 60% Schist + 40% pfg. |
| 11. | 62 | 69 | 80% pfg, 20% Schist. |
| 12. | 69 | 79 | >90% qz biot - sch. |
| 13. | 79 | 81 | Schist is sulphide bearing. |
| 14. | 81 | 93 | 100% Schist. |
| 15. | 93 | 99 | 90% Schist but approximately 10% of featureless, light brown, non - foliated, phlog bearing kimberlite. Definitely not Schistose sample submitted for petrography under consignment no mak/92/043. |
| 16. | 99 | 110 | From 95m - EOH at 110m is dominantly qz - fsp biot - Schist with the occosional pfg inclusions. |
