This shows the June Qtr profit for OM Sarawak. of RM 12,897,750 for 25% OMH share is AUD$38.7 million.
What is surprising is the increase over the March Qtr which was RM 11,974,000 for 25%  OMH share was AUD$35.9 million, the volume of sales was down by a total of 26,847 tonnes of alloys in the second quarter due to the 2 local festivals, but the income was nearly $3 million more.  Therefore getting a higher margin per tonne, but it seems excessive.
Possibly OMH gets extra SSS from the partnership as the overall profit from smelting on the OMH Financial Report is $87.5 million this is $12.9 million  more than the sum of $38.9 + $35.9 million. Obviously OMQ China  is added into the smelting contribution of $87.5 million but it would only account for about $3 million max.
Any suggestions, where the extra $10 million comes from?
