The article below from Mineweb makes clear that Golden Minerals is not the only junior focusing on higher grades to look more attractive. The last paragraph of the article resumes nicely what the pro's and con's of this approach are:

"In going after grade the hope for juniors, in some of these cases, is that banks and markets will be more liable to bite on a smaller - if potentially tastier - morsel. As well, in a junior gold market where a million or two ounces gold in resources seems increasingly common, grade looks to be an important way to differentiate oneself from the competition. One risk in sacrificing size for grade, however, is that a junior may diminish its chances for takeover by making a project seem less sensible for intermediates or majors. Big producers may be hungry for growth, but they are also picky eaters. It has proven a difficult palate for juniors to please."
