The Page Authority will be 1 as it'll be a brand new page. You don't create a page with an instantly high PA, it has to be earned. Take the BBC, for example; if they create a news story today the page will have a PA of 1 but a DA of 100, but most SEOs would love a link from the BBC!
News websites are constantly adding new pages as new stories break. It's unlikely these types of pages will get huge PAs as, let's face it, yesterday's news won't continue to attract many backlinks after day one or two of the story breaking.
Keep up the good work! You should certainly see some positive results if you keep building links like that!
