The following is the Mining Manager's re- port for five weeks ending 11th June, 1896:-
Raub Hole. The main drive going in on the course of the lode at the 220 ft. level is now in 66 feet north from the crosscut. There is no change to report in the appearance of this drive. The lode formation still continues small, 3 to 4 in., and shows no gold. The country, is hard blasting black slate with a number of small leaders coming in from the east side, but they carry no gold.
The Intermediate Drive going in south from the winze is now in 109 feet. I regret to say there is no improvement in this drive, which should have cut the ore chut before this. I am afraid this chute of ore has pinched small. owing to the hard nature of the ground, or it is dying out In the stopes coming in over the back of this drive the lode is from 6 to 15 in. wide and carries fair gold. In the stopes going north the lode is from 6 to 15 in. wide and carries fair gold. These stopes rise as they go north and will soon run out into the level above. So far the section between the 120 and 22 ft. levels has been a disappointment.
CHINA OVERLAND TRADE REPORT.
Monday, the 7th inst., a rough clean up took place; 1,464 tons of ore yielded 1,500 oz. amalgam. Crushing was resumed again the same day."
It is
General. During the past five weeks the weather has been very hot and dry. There has been a change the last day or two; several showers have fallen, which liave cooled the air and ground. The camp is remarkably healthy, there being practically little or no sickness. Mr. L. J. Fraser, Tras, and this Company have supplied a good deal of medicine to coolies working on the Selangor Pahang main road. There are about 2,000 coolies employed on the Tras and Raub sections of this road. certainly not to the credit of theso Govern- ments that there is not a shred or a dresser to attend to the sick or injured. The nearest place where medical aid. can be got is Kuala Lipis or Kwala Kubu, 40 and 30 miles distant.
Mr. John Anderson, one of the Singapore directors of this Company, visited Raub last week and spent several days inspecting the un- derground working of the different mines. He also visited the falls on the Sempam river and the proposed site of the electric power. As the water in the river is now about as low as it is known to be, a good opportunity of ascertaining the minimum flow can be got. There is cer tainly three or four times more than we are likely to require for a long time.

made up as follows:-
*346 ft. 6 in. 1,000 tons.
.600 tons.
400 tons.
August Shaft New Leader Milling. This was carried on during 26 days, crushing 1,000 tons, yielding 442 ozs. 2 dwts. of melted gold.
Calcining. This was carried on during 28- days, treating 42 tons of concentrates yielding 75 oz. of melted gold.
Of course my weekly letters will have told you why both this plant and the mill did not work full time.
Cyanide Works. The clean-up from 610 tons. of clean tailings resulted in a yield of 237 ozs. 5 dwts, of bullion valued at £2 2s. 8d. per oz. These works are now running full time on similar material and the next clean-up will be commenced about the 16th proximo. This pro- cess may now be said to have really commenced on a large scale, and I look forward to some years of profitable work for it.
General. A very large amount of work which may properly come under this head has been carried on and, everything considered, good progress has been made. The 9 in. plunger pump for tailings has been fixed in a most substantial matter and will soon be ready for use. One of the small Robey engines and the Sinyum boiler have been erected to work
ready for use.
Bukit Koman.-This mine still continues to open up remarkably well. In the main drive going north at the No. 1 (149ft.) level the lode in the face is fully 15 feet wide and shows payable gold all through, the whole of which is being sent to the mill for crushing. The ground is good working ground and a large quantity of crushing stuff is being sent from here. This drive is now in over 300 feet from THE PUNJOM MINING CO., LIMITED. this pump, till such time as the water wheel is the crosscut and the lode for the whole distance will average from 14 to 16 ft. wide, every particle of which is payable.
The South Main Level still continues to look
remarkably well. In the face of the drive there is a well defined solid lode fully 6 feet wide be tween clean well defined walls, and shows good gold all through. This is one of the best formed lodes I have yet seen at Raub. Fair progress is being made in driving this level, which is now in 364 ft. south from crosscut.
In the Leading Stope coming in 140 ft. be- hind the face of the drive the lode is fully 15 feet wide, the whole of which is being sent to the mill. These stopes and the two drives are supplying almost all the crushing stuff sent from this mine. There is no change in the stopes above this level, and there is very little work doing in them, as we do not require the stuff.
No. 2, 250 feet level. The lode has been met with in this level at 19 feet in from the shaft; we are now about 6 feet in it with no signs of being through. The lode has a clean well de- fined hanging-wall and is very hard and solid. Fair gold can be seen in the stone as far as we have gone, but it is too early yet to say much about it. This, I believe, is the greatest depth at which gold has been got in the Malay Penin- sula and marks a very important epoch in the history of Raub and gold mining in Pahang, as it proves conclusively that the lodes and gold live in depth here the same as in other countries. It is my intention as soon as we cut through the lode to open levels both north and south on it and resume sinking the shaft another 100 feet.
The new 10-in. pump, which has now been working over a month, is giving every satisfac- tion and easily keeps the water out at ten strokes per minute,
Western Lode.--This mine still continues to look very well. The lode continues to make south into new ground and shows fair gold. The stopes continue to turn out their full com plement of crushing stuff, with every promise of continuing to do so for a considerable time. The water in this mine still causes a lot of trouble with the pumps owing to the acidity of the water. Last week we had to take the pump out of this shaft and replace it by another, as the iron work was completely eaten away by the water.
Bukit Malacca.-Preparations are now being made to put in another boiler and an additional 8-in. pump into this shaft. When this work is completed the sinking of the shaft will be resumed. It is to be hoped with two 8 in. pumps and the additional boiler power we shall be able to get down the required depth of 150 feet before opening out for the lode.
Battery. This has been kept at work full time fince the date of my last report. On
CYANIDE PROCESS
The Secretary of the Punjom Mining Co., Limited, advises us that he has received the following telegram from the Mine, being the result of the cyanide clean up (second run):-— yielding 293 oz. of bullion of an average assay Eight hundred and sixty tons tailings treated,
value of £1 18s. per oz."
MONTHLY REPORT.
The Secretary also advises us that he has re- ceived the following progress report on the work carried on during the month of May from the Manager of the mines:-
Mining-This has again had our best átten- tion and fair progress has been made.
August Shaft, 200 ft. level-A good deal of work has been done at this level, but I regret to say we have not yet met with the success I had hoped far. This applies more particularly to our western chute of ore on the course of east and west reef. We have put out drives in search of this ore body and although these have crossed its proper course, nothing of value has been found. We are now putting a cross. cut north-east to see if it has been thrown in that direction, and shall soon prove whether or not it is continuous in depth. That we shall find it directly there can be little doubt, as at the intermediate level it is fully. 15 feet wide in places and appears strong enough to go to any depth.

Ten new hand buddles for replacing the blanket tables in the mill have been made and are ready to lay in position. All the parts of the water wheel are now on the mine, as also all the heavy foundation logs, and the necessary fram- ing and planks for the wheelpit: Large quan- tities of concentrates and tailings have been shifted to make room for the main tail race from the Jalis River and a large section of the race completed:
Contracts for the remaining section have been I expect to see much of these completed by the let, as also one for excavating the wheel pit, and
end of the coming month.
The brick kiln and drying shed and about 5,000 bricks are ready for burning.

All the
Roads into the jungle for firewood and other timbers have been extended and a track cut to another timber reserve, where there is enormous quantity of good timber. flood gates for use in the race between the mill and the main dam are in position, and men are now preparing the necessary timber for raising the retaining wall of the dam itself.
Labour. This was deplorably short in the early part of the month, but I am pleased to say it is again coming in more freely..
Health. This is by no means good, but I am hoping for an improvement with the dry. weather we are now experiencing here.
Rainfall. The total rainfall for the month is 33 inches.
The north drive on Gillies' reef is still in good looking country; but up to this time it shows nothing of value. And this applies also to the south drive on the course of the north HONGKONG RIFLE. ASSOCIATION. and south reef at this level. The stopes in the back of the course of the north and south reef have improved, and are now producing fairly large quantities of ore for the mill.
Intermediate Level-This point continues to give a large quantity of fair grade ofe for the mill, and from appearances will do so for some time yet. The winze sinking below this level on the course of the chute of payable ore has passed through the quartz and is now in what appears to be footwall rock. This is altogether unexpected and shows that the reef has charged its dip and direction entirely. It is now dip- ping to the north-east at an angle of about twenty-five deg. from the horizontal and carry. ing a course of about W. 45 deg. N. instead of east and west as hitherto. I need not tell you this change has led to the driving of the crosscut referred to in an earlier part of this report.
"
110 ft. Level-Stoping is being carried on over the back of this level on the course of the the east and west reef and I am pleased to say ore mined is payable. We can now see a pretty large reserve of ore here, too.
