The gold space is never short on excitement, and the second quarter of 2015 was full of interesting developments for the yellow metal. Besides big investments from companies like Zijin Mining (SSE: 601899,HKEX:2899) and Barrick Gold (TSX:ABX,NYSE:ABX), there was some major M&A activity. For example, Alamos Gold (TSX:AGI,NYSE:AGI) and AuRico Gold (TSX:AUQ,NYSE:AUQ) announced plans to merge in April, while more recently Oban Mining (TSX:OBM) revealed it's gunning for a five-way merger with Eagle Hill Exploration (TSXV:EAG), Temex Resources (TSXV:TME), Ryan Gold (TSXV:RYG) and Corona Gold (CSE:CRG). Here's a look at the Investing News Network's (INN) top gold stories from the past three months. Many include stock picks from thought leaders, although some cover key events that occurred during the period. 1. Brent Cook Talks Junior Mining Stocks Coming in at the top of the list is a recap of Brent Cook's presentation at the recent Canadian Investor Conference. Cook is an analyst who publishes a newsletter called Exploration Insights, so naturally attendees were eager to hear his thoughts on the gold space. He talked about the lack of new discoveries in the mining sector, the lack of funding in the gold sector and the growing gap between production levels and new mine development. Cook also offered insight about a variety of gold companies. 2. Survey: Will the Gold Price Hit $5,000? This article looks at recent price predictions made by Peter Schiff, president and CEO of investment firm Euro Pacific Capital. He sees the gold price climbing to $5,000 per ounce, and it appears many agree with him — INN turned the question of whether gold will indeed rise that high over to readers, and just over half of respondents said it's only a matter of time.
