Uses For Magnesium Hydroxide

SIRIUS MINERALS ORD 0.25P : Preliminary Results for the Year Ended 31 March 2011

Chairman?s Statement

Dear Shareholder,

When I wrote to you last year in my first Chairman?s Statement, I set out the case for the Company?s decision to focus on developing into a New Potash Powerhouse based upon multiple projects in OECD countries. A year on, with increasing global potash consumption and accelerating food price inflation becoming an international issue, I am convinced we have set the correct strategic direction and I am pleased to report that we are now making good progress down that path.

Increased pressure continues to be placed on a diminishing arable land bank as a result of population growth, rapid urbanisation in the developing nations and the transition to higher protein and higher value diets around the globe. These, amongst other factors, are contributing to the increasing long-term demand for potassium enriched fertilisers to improve the productivity of farmland in both developing and developed nations alike.

Of late the investment community has deepened its understanding of the fertiliser sector and potash in particular, not least as a result of the unsuccessful BHP Billiton bid for Potash Corporation of Saskatchewan in August 2010 and the subsequent acquisition of PotashOne by K+S AG. This improved understanding is leading investors to better appreciate the range of potassium based fertilisers that are required in the market. A new lexicon of terms has become common place such as polyhalite, muriate of potash (MOP) and sulphate of potash (SOP). The debates are now no longer based simply on the scale and risks associated with any potential project, but on the likely make-up and related value of the contained potash.

How has all this impacted our Company in the year under review?

Quite simply, it led the Board to better rank and prioritise the Company?s portfolio of assets. It also helped us recognise the value of securing projects focused on premium potash products such as SOP given that they can trade at up to a 50% premium to the more common MOP products.

We were delighted to finalise negotiations to acquire York Potash Ltd in January 2011. The York Potash Project in the UK undoubtedly has the potential to rapidly become a ?tier one? company making asset. It provides Sirius with a world-class project that has every chance of becoming a major potash production centre and a significant contributor to both the North Yorkshire and United Kingdom economies. The product suite from the sylvite and polyhalite is extensive and potentially includes SOP, MOP, magnesium hydroxide, magnesium oxide and gypsum.

Medicinal Uses of Magnesium Peroxide | Magnesium Hydroxide

Magnesium when taken helps the body in a number of ways including in the proper functioning of the nerves and muscles. Magnesium peroxide in liquid form looks like milk and when in solid form, it is commonly known as brucite. Many laxatives and antacids contain components of magnesium peroxide. As a compound, magnesium peroxide can be prepared by precipitating magnesium salts with potassium, ammonium hydroxide or sodium. Here we look at some of the medicinal uses of this compound.

Magnesium suspensions can be used to relive stomach disorders by neutralizing the acid in the stomach. The compound can also be used as a laxative to reduce constipation and enhance bowel movement. In many cases, taking magnesium peroxide will lead to diarrhea which carries away supplies of potassium. Therefore, it is important to increase the intake of potassium if you have diarrhea induced by consumption of Magnesium Hydroxide . In case, you fail to take potassium, you are likely to suffer muscle cramps.

Sometimes, magnesium peroxide is used as an antiperspirant. When used for this function, it is usually in the form of armpit deodorant. The suspension of magnesium peroxide can also be used to fight aphathous ulcer or canker sores.

Although, magnesium is typically meant to be an antacid to relive constipation, it can also be effective in relieving heartburn and indigestion cases.

Magnesium peroxide in the liquid form can also be used to relive a number of scalp conditions like dandruff and seborrhoea. When used for this purpose, the mineral is applied then massaged onto the skin after washing and drying it. Although the effects have not been scientifically proved, it is believed that the application can lead to relieve or such scalp conditions. Magnesium peroxide can also be used as a folk remedy to relieve skin conditions like acne. When used for this purpose, the suspension is applied a clean skin, then let it dry on the skin before washing it off. Although, magnesium is taken orally to facilitate proper functioning of the body nerves and muscles, very little is absorbed by the body in normal conditions.
