The picture is clear - there is steady growth at Sandstorm. Each year the company adds new streaming / royalty contracts and lifts up the amount of gold equivalents delivered.

However, let us look at the company's sales from a short - term perspective (two years). Here is the appropriate chart:

Well, now the picture is not that bright - since the first quarter of 2017 the sales have been going down (look at the red arrow). 

What is the takeaway for investors? Well, I would not bother too much about the short-term perspective. Precious metals mines do not deliver  the same or only higher amounts of gold and silver each quarter - sometimes production goes down for a while. It is the long-term perspective that counts so...relax. Sandstorm is on the right track.
