Removing Price from WooCommerce Product Category Page

Hello, on our site (password is Lilli*999), if you go to:

We want to remove the prices that are displayed on all of the products, but we want the price to REMAIN whenever someone clicks and goes to the single product page. We want to do this site-wide, so that all of the product category pages have the prices removed. Could you help me do this?

Thanks very much,
