hey im new to this site but sorry that is absurd there isnt any mother lodes in new york but new york has gold glaciers brought down gold and spread it as far as the pa border in some places so around the finger lakes is a good place to look east in the Catskills you might be able to find ancient alluvial conglomerates that contain gold north in the Adirondacks some rocks may host gold and it also can have glacial gold along the Hudson you can find placer from vermont and Adirondacks. and in long island there might be some placer and the metamorphic rock that makes up long island could host some gold. like i said above there is some gold in new york not a lot but with the right geological geographical and watershed knowledge you can find some. im not as knowledgeable in far western new york im assuming you might be able to find a tiny amount of gold that made it into the Allegany area and as far as the great lakes go there is some i highly doubt dredging would be profitable but you can find some if you do enough geographical research and learn to read glacier movements
