It doesn't produce an EPUB as you'd expect from a regular MOBI/AZW3->EPUB Conversion, just something universal that the calibre viewer can handle - sometimes called a 'mini conversion'. Because EPUBs aren't mini-converted, it's convenient to think of mini-conversion as conversion to EPUB.

Open a MOBI in the Viewer that you've not viewed before, and then search the content of calibre's cache folder for the book title. It'll be found in a folder named something like <cache>\ev2\f\tmprjokif which will contain something like this:

<cache>\ev2\f\tmprjokif\images (folder)
<cache>\ev2\f\tmprjokif\calibre-book-manifest.json
<cache>\ev2\f\tmprjokif\calibre-book-metadata.json
<cache>\ev2\f\tmprjokif\index.html
<cache>\ev2\f\tmprjokif\styles.css
<cache>\ev2\f\tmprjokif\titlepage.html

Now do the same with an EPUB, in the cache you'll find the unpacked EPUB.
