Filer: Sprott Physical Gold Trust

Pursuant to Rule 425 under the Securities Act of 1933

Subject Company: Central GoldTrust

Commission File No. 001-32934

Date: August 19, 2015

Dear Unitholder,

THE SPICER’S HAVE STACKED THE DECK AGAINST YOU AT CENTRAL GOLDTRUST

It was recently revealed in the Ontario courts that Ian McAvity, Central GoldTrust (GTU)’s former Lead “Independent” Trustee has a personal financial arrangement with the Spicers that seemingly directly conflicts with your interests.  McAvity receives 6% of the gross revenue of the Spicer-owned administrator for Central Fund of Canada Limited. The key details of these payments, including their significant amount and lifetime term, have never been publicly disclosed to GTU unitholders.  In the past three years, McAvity received CDN$1.4 million from this arrangement. From 2005 through 2014, he received CDN$3.3 million.

GTU Trustees replaced McAvity as Lead Trustee with Glenn Fox - another existing Trustee who has served on the board for this underperforming vehicle since 2012 - but only after Sprott unveiled the previously undisclosed McAvity arrangement.

Shockingly, McAvity still remains a GTU trustee, and GTU still claims he is “independent”.   GTU is simply reshuffling the same conflicted trustees who are seemingly beholden to the Spicers, lack any industry experience (according to McAvity himself!) and are seemingly not concerned with acting in your best interest.

SHUFFLING THE DECK DOES NOTHING TO HELP UNITHOLDERS — DON’T TURN A BLIND EYE TO YOUR MISMANAGED INVESTMENT

SPROTT’S OFFER WILL PROVIDE IMMEDIATE VALUE AND SECURITY

Sprott is offering GTU unitholders an immediate exchange premium and the opportunity to own an investment that will not only better reflect the value of your physical gold holdings on an immediate basis — but will also ensure that your investment is managed by a regulated entity with transparent, experienced and professional managers that can deliver value on an ongoing basis.

Only by tendering your GTU units will you become an owner of a best in class physical bullion vehicle and get the peace of mind that comes with owning an investment that offers:

·VALUE: Sprott’s Physical Gold Trust reflects the value of physical gold

·TRANSPARENCY: Sprott Physical Gold Trust is managed by transparent, professional managers with a superior investment platform

·SECURITY: Sprott Physical Gold Trust’s bullion is held in government-backed gold storage at the Royal Mint in Canada

·LIQUIDITY: Sprott Physical Gold Trust offers physical redemption capabilities including the delivery of gold bars virtually anywhere subject to redemption of certain minimum amounts.

THE SPROTT ADVANTAGE IS CLEAR — BUT YOU MUST TAKE ACTION

It is important you act now.  The Sprott offer for GTU is open for acceptance until 5:00pm on September 18, 2015, unless extended or withdrawn.
