Brent Cook does not like anything that is considered "low grade", including any poriphery style deposits. He never liked CUU since it was considered a "low grade" type deposit in the far north and hence has never really recommended buying CUU. This was before the discovery of higher grades in the Paramount zone but even so we remain off his radar. IMHO, he really doesn't understand the economics of poriphery style deposits enough to feel comfortable recomending them in his newsletter. His picks are mostly high grade smaller type deposits.
