From this it will be seen that the ores of this locality are siliceous and 
highly phosphoric manganiferous iron-ores. 
There is still another outcrop of very manganiferous limonite situated 
J mile or so S. .'55^ E. from Matkamliatu village and striking N. 155° E. 
It is on the west side of the road. 
4. Tekrasai (Tekrahatu). 
Half a mile almost due north of the village is the principal excavation 
made by Messrs. Hoare, Miller & Co. It is on low ground and has revealed 
a nearly horizontal bed of ore restmg on purple quartzites. The section 
seen in one place was as follows: — 
1'8" ore, including a 1 to 2 inch band of vein quartz. 
6" purplish jaspery quartzite veined with psilomelane. 
5* lavender slate replaced by ore in places. 
l'6"-f decomposed purplish sandstone. 
4'1" total. 
The ore band varies from I'S" tol'O" in thickness and is composed of 
layers of psilomelane J to 1 inch thick, sometimes very good, but usually 
showing included siliceous remains. Some of the ore is cavernous and 
botryoidal. This bed of ore could be tracer! only over a small area and 
must thin out in all directions. Perhaps 10-15 tons of ore had been col- 
lected, and from the heap that contained the best ore — the others required 
much cleaning — a sample was taken, which gave the following partial 
analysis (J. & H. H. Pattinson): — 
Sample No. A. 33. 
Mn02 no -31 
MnO 5-51 
FegOs 1-74 
BaO 4-47 
Si02 (combined) 3-50 
SiOo (free) 4-80 
P2O5 0-99 
Arsenic oxide (As O5) ........ 0-033
