Thank you very much for introduction. Good afternoon ladies and gentlemen. In fact, there going to be some over lips in the presentation, but as Keith already pointed out its going to be much more operational, less strategic than Gavin's presentation. So, let me just present our company on the next one or two pages.

Hawar Power Minerals is basically sourcing industrial minerals from overseas mainly steel and power pumps. We supply these products to clients mainly readymades and pre [xx] companies in the Gulf region. We build complete supply chains, meaning we're building supply chains from the source, we are not buying from traders typically. But we would just take these materials from the source and take it to the end customer, while investing into our own facilities like transport facilities, storage and other.

We would also look after quality, we have agreement with our customers and our source and how to manage the quality of this product, and if necessary, we also would supply technical applications support. The company is still a relatively young company. We were founded back in 2013 in summer as Qatari/ German joint venture.

Quick look at our shareholders, there's a local shareholder of course in Qatar which is the Hawar Group, it's a family owned Qatari Holding company. They have interests in various industries, mainly energy, engineering, contracting as well as logistics. Our German shareholder on the right side is the company Steag.

Steag power mills. They are actually a power generating company that are operating qualified power plant in Europe, mainly Germany about 10, 000 Megawatts installed. They have a long time experience in this field for 40 years, they have been active round about 15 countries. And apart from generating power they're also into Associated services like, engineering, recycling and managing byproducts which makes the market leader for byproducts in Germany and possibly in Europe.

They're roughly handling about 4 million tonnes, mainly fly ash and gypsum. You might just seen this one before it was just quite tempting because it illustrates very well the use of cemententatious materials in history, and this example it is fly ash, on the left side you see the Pantheon which was built with lime and volcanic ash 1900 years ago.

It was finished After Christ 115, and on the right side, quit the opposite, a modern record breaking structure, the Burgh Khalifa, which was finished as we all know in 2009, also build with the help of fly ash and other cementatious materials. So what kind of materials do we find in the region of course, there's fly ash as we mentioned before, imported mainly from India.

It's from [xx] power stations as captured in the electrostatic filters and can be added either to concrete or cement. We have the natural pozzolans, this is volcanic ash, it's excavated in volcanic or ex-volcanic areas. There is also a little bit around in the region back in Saudi and the South of Saudi Arabia, we find some natural pozzolans.

There are Silica fumes coming in from China and European sources. These are products from electric arc furnaces. They are also kept from the fum gas that mostly intensified because they are quit challenging to transport. And last but not least of course, there is GBFS and GGBFS. It's from iron blast furnaces.

It's quenched with water and then granulated, and then it held either into cement as GBFS and co-ground or added to concrete as GGBFS material. There has been in the past, I noticed there has been some confusion about denomination, so that's why I brought this slide just what we understand slag GGBFS and GBFS.

On the left side we see a photo of liquid slack coming out of the blast furnace which is then quenched with water getting it product, reusing the product in the middle of the picture which is granulated slack after quenching on the [xx]. This material is ground, you get GGBFS ground granulated blast furnace slack. Having a look at the statistics of this materials, on the left side you see the different materials, OPC, GGBFS, Fly ash and Silica Fumes. They mainly differ in particle size and as well
