GOLDFIELD ANNOUNCES STRONG SECOND QUARTER EARNINGS

MELBOURNE, Florida, August 13, 2012 - The Goldfield Corporation (NYSE MKT: GV) today announced strong earnings for the three and six months ended June 30, 2012. The Goldfield Corporation is a leading provider of electrical construction services headquartered in Florida with operations primarily in the southeastern, mid-Atlantic, and western regions of the United States. Goldfield is also engaged, to a much lesser extent, in real estate development activities on the east coast of Florida.

Six Months Ended June 30, 2012

Revenue for the six months ended June 30, 2012 more than doubled, increasing to $36.2 million from $16.4 million in the comparable prior year period. This increase was attributable to higher electrical construction revenue. Because of improved results in the electrical construction segment, the Company’s operating income for the six months ended June 30, 2012 dramatically increased to $6.7 million from $79,000 in the same period in 2011.

Income from continuing operations before tax for the six months ended June 30, 2012, significantly increased to $6.7 million from $50,000 for the same period in 2011 as a result of our improvement in the electrical construction segment.

Net income for the six months ended June 30, 2012 increased to $5.1 million, or $0.20 per share, from $21,000, or $0.00 per share, in the comparable prior year period. These earnings included the reduction of our previously recognized deferred tax valuation allowance, which resulted in the recognition of a provision for federal income taxes during the current period.

For the six months ended June 30, 2012, the electrical construction segment’s operating results showed substantial improvement, with revenue increasing from $15.6 million to $35.6 million, and operating income increasing from $1.1 million to $8.1 million. Growth in this segment reflects a broad-based improvement across all areas of our electrical construction business, with particularly dramatic growth in Texas.

With no significant real estate projects under construction, results for the real estate segment remain relatively constant. For the six months ended June 30, 2012, the real estate segment had revenue of $639,000 and operating income of $48,000, compared to revenue of $776,000 and operating income of $156,000, respectively, for the like period in 2011.

Three Months Ended June 30, 2012

Revenue for the three months ended June 30, 2012, more than doubled to $18.5 million from $7.5 million in the comparable prior year period. The Company’s operating income for the three months ended June 30, 2012 jumped to $4.0 million, compared to $80,000 for the same period in 2011.

Income from continuing operations before tax for the three months ended June 30, 2012, increased to $4.0 million from $51,000 in the same three month period in 2011, also as a result of the improvement in our electrical construction segment.

Net income for the three months ended June 30, 2012 was $2.4 million, or $0.10 per share, compared to $32,000, or $0.00 per share, in the comparable prior year period. These earnings included the reduction of our previously recognized deferred tax valuation allowance, which resulted in the recognition of a provision for federal income taxes for the period.

For the three months ended June 30, 2012, the electrical construction segment’s operating results improved significantly with revenue increasing to $18.5 million from $7.5 million and operating income

increasing to $4.8 million, from $797,000. The increase in revenue was also largely attributable to an increase in demand for our electrical construction services, particularly our transmission work, for the current three month period, when compared to the same period in 2011.

For the three month periods ended June 30, 2012 and 2011, the results of the real estate segment were not significant.

John H. Sottile, Goldfield’s President and Chief Executive Officer stated, “We are pleased with the continued broad-based growth of our electrical construction business. With our electrical construction backlog at June 30^th reaching $60.3 million (compared to $3.4 million at this time last year), the prospects for this business remain brighter today than at any time in recent history.”
