Metres 1 ' 1 was wol "k e d to some depth on both legs; the 

 vertical cleavage is strongly developed even 

 in the quartzite, and indicates the exact direc- 

 tion of the anticline; the intersection of the 

 cleavage and bedding planes is at right angles 

 indicating the centre of the dome. Large 

 barren veins of coarse white quartz cross the 

 anticline at right angles, and are probably 

 the result of the arching of the fold producing 

 the east and west pitch. At the foot of the 

 hill, 125 feet (38 m.) north of the anticline, 

 the footwall of a small lead adjacent to the 

 Harrison lead dips north 65 and is also inter- 

 sected by the same large cross veins; the lead 

 is largely made up and enriched by very small 

 angulars entering from the footwall side, but 

 is not affected by the large cross veins. The 

 strata and interbedded veins on both limbs 

 strike parallel with the axis of the anticline.

1,247 m. the footwall of the Morell lead curves slightly 

 and dips north 57 ; corrugations on the foot- 

 wall caused by the intersection of cleavage 

 and bedding planes pitch easterly at a low 

 angle indicating the pitch of the dome. On 

 the footwall is a fault having a horizontal 

 displacement of 15 inches. 



4,345 ft. Close by on the left isW. A. Brennan's stamp- 



1,313 m. mill with 2 batteries and amalgamating tables, 

 one Wilfley concentrating table, water-power. 

 Footwall of a vein dips north 52 , corrugations 

 pitch east.

1,383 m. Hardman's old stamp mill on the right, with 

 2 batteries and amalgamating tables, water- 

 power and Pelton wheel, has produced probably 

 more than half the gold extracted from the 

 Oldham deposits. On the east side of Black 

 brook, opposite the mill, a good section of the 

 anticlinal fold is exposed where superimposed 

 beds of quartzite and slate curve broadly on 

 the apex; between a bed of slate and quartzite 

 is intercalated a small vein, deeply corrugated, 

 showing gold at the point of intersection of an
