Kempfield is one of those revival silver projects that spivs who mine shareholders dust off and trot out when the price of silver takes off and people get excited. The managements of these illusions get rich and are a f'g disgrace because they prey on the most naive investors and are assisted by brokers and newsletter writers. They financially destroy investors who believe their words and smiley faces. All these primary silver projects go bust eventually. Houses of cards. They run out of chumps after hyper-dilution - Golden Cross Resources, Macmin Mining, Malachite Resources, Cobar Consolidated .. others I cant remember from previous silver crazes. Same will happen with SVL anf f'g Bowdens which Kingsgate couldn't make a go of. Another El Crapola Ag project.
About Kempfield in particular, those grades aren't good for a primary silver project. Compare for instance to MMA (do not hold, do hold RDM) MMA from memory is claiming 100g/t silver, plus 5% lead, plus gold and copper in their high grade starter pit specs. Primary silver alone needs a big high grade shallow resource it seems to justify start-up capital. Processing cost, esp in Australia, is expensive relative to value of product. A primary silver producer has to compete with lower cost producers of silver as a by-product - like Cannington.
