WordPress Blog, only use archive for current page?

I am building a WP site, which will have a News and Blog.

They will be in separate pages, One for news and one for Blog, which will be separated by categories.

So for example, I have this code on ‘News’, which stops the loop getting posts:

<?php 
    $uncat = get_cat_ID('uncategorised');
    $uncat2 = get_cat_ID('blog');

    $args = array(
      'posts_per_page' => 3,
      'category__not_in' => array($uncat, $uncat2)

      );
    $loop = new WP_Query( $args );
    while ($loop->have_posts() ) : $loop->the_post();
    ?>
    <div class="col-md-12 col-sm-12 col-xs-12" style="padding-left:0; padding-right:0;">
      <a style="color:#333; text-decoration:none;" href="<?php echo get_permalink(); ?>">
        <div class="postsize">
          <div class="leftfloat" style="float: left; padding-right:20px;">
            <?php echo get_the_post_thumbnail( $page->ID, 'categoryimage', array('class' => 'faqposts')); ?>

          </div>
          <div class="contentfaq">
            <h4><?php the_title(); ?></h3>
              <span class="entry-date-blue"><strong><?php echo get_the_date('d/m/y'); ?></strong></span>

              <?php $trimexcerpt = get_the_excerpt();

              $shortexcerpt = wp_trim_words( $trimexcerpt, $num_words = 10, $more = '… <br/> <a href="">Read More ...</a>' ); 

              echo '<a style="color:#333; text-decoration:none;" href="' . get_permalink() . '"><p>' . $shortexcerpt . '</p></a>'; 

              ?>
            </div>
          </div>
        </div>
      </a>


    <?php endwhile; ?>
    <?php wp_reset_query(); ?> 
  </div>

This works fine, but I also have ‘Archives’ on the right hand side, which filters by date posted. The issue is, this will get posts from News AND blog, which defeats the idea of splitting them up.

Is there a way to split these up, so if the user clicks ‘March 2015’ on the archive, it will only get the posts from this month from NEWS?

Here is my current code for Archive.php

     <?php if (have_posts()) : ?>
  <!-- First, the loop checks whether any posts were discovered with the have_posts() function. -->



  <!-- If there were any posts, a PHP while loop is started. A while loop will continue to execute as long as the condition in the parenthesis is logically true. So, as long as the function have_posts() returns a true value, the while loop will keep looping (repeating). -->
  <?php while (have_posts()) : the_post(); ?>
  <div class="col-md-12 col-sm-12 col-xs-12">
    <a href="<?php echo get_permalink(); ?>">
    <div class="postsize">
      <div style="float: left; padding-right:20px;">
        <?php echo get_the_post_thumbnail( $page->ID, 'categoryimage', array('class' => 'faqposts')); ?>

      </div>
      <h5 class="captext"><?php the_title(); ?></h5>
      <span class="entry-date-orange"><?php echo get_the_date(); ?></span>
      <?php
      foreach((get_the_category()) as $category) { 
        echo ' | ' . $category->cat_name; 
      } 
      ?>

      <p style="margin-top:10px";><?php the_excerpt(); ?></p>
    </div>
  </a>
  </div>
  <?php endwhile; else: ?>
    <p><?php _e('Sorry, no posts matched your criteria.'); ?></p>
  <?php endif; ?>
