Ann: MEDIA RELEASE H1 2022 NPAT USD60 Million UP 231%, page-185

Its possible that the recent seller has run out of shares. Most of the downward action now is by the shorter who now accounts for up to 50% of sales ie 17th Oct. As the share price recovers the shorter will become more active, either trying to push down the share price or panicking trying to buy back the 250,000 shares. Time will tell.

Silicon metal will be a game changer for OM Sarawak, the two furnaces that have been idle for two years will be selling high grade silicon metal in a few months time. The current price for 2202 silicon metal in China is 32,000 yuan = US$4,420/tonne.
The amount of power required is 14,000 - 16,000 kWh /tonne.

"Metallurgical (MG) silicon is produced at the rate of millions of tons/year at a low economic cost of few $/kg and an energy cost of 14–16 kWh/kg."

Any change in power prices has a big influence on the price of silicon metal and since the Chinese produced 6 million tonnes in 2021 and 95% of world production.
There aren't many places in the world where the power prices are lower than Sarawak and with the 20 year power contract the gap/margin will only increase.

Articles that I've read state that about 6 tonnes of raw materials. ie 2 tonnes of quartz (SiO2 + 2C = Si =CO ) so about 4 tonnes of charcoal or coke are required to produce one tonne of silicon metal.

"Typically, step two takes up to six metric tons of raw materials to make one metric ton (t) of silicon. A typical furnace consumes about 15 megawatt-hours of electricity per metric ton (MWh/t)⁸ of silicon produced, plus four MWh/t for ventilation and dust collection."

Using the power requirement and the fact that China produces most of the worlds silicon metal then the price has a lower floor set by China's power cost.
The difference in power cost for China vs Sarawak is about US$900/tonne.
This is why OMH in presentations has mentioned that this will be the most profitable alloy/furnace.
